Title: What breakout do you need/want?
Post by: Sjaak on December 16, 2010, 10:42:49 pm
We recently added a breakout board to our portofolio and we have some more to come:

- MMA7455L 3-axis accelerometer (released)
- MCP2200 USB-to-serial with GPIO (soon to come)
- FT2232H hispeed usb-to-serial with GPIO (soon to come)

In the MMA7455L thread several users suggested other chips to breakout:

- I2C/SPI sensors, ADC/DAC, memory (IPenguin)
- accelerometer/gyro combo (serial interfaced) (Arhi)

So I guess you want DangerousPrototypes to develop some more breakoutboards. We like to hear which chip(s) you like to see on a handy PCB. These are on my wish list:

- display + buttons (every project needs an userI/O)
- CPLD/FPGA (to quickly come up with logic you don't have in your scrapbox)
- camera

What do you want to breakout?

CPLD! ... with McBSP serial interface over 16-pin Hirose (*)
Well, I wouldn't mind if it also has SPI or I2C.  ;-)

(*) The 16-pin Hirose would interface to a TMS320VC5506 board that I designed.  It's a custom pinout that also feeds power to an 8-channel AD.  If you do design a CPLD/FPGA breakout, drop me a line and I'll try to squeeze my connector on there somewhere - hopefully it won't make the desired size impossible.

You got any cpld particular in mind?

I have somewhere an untested design for a 74xx logic emulator based on the xc9572xl. it has a .3" DIP20 footprint for breadboarding. I designed it to replace 74xx and 4xxx digital chips and not as generic cpld board. I was inspired by this topic: http://dangerousprototypes.com/forum/in ... 61#msg7661 (http://dangerousprototypes.com/forum/index.php?topic=611.msg7661#msg7661)

Edit: how about the XC2C32A (the one used in the busblaster v2 update)?
Title: Re: What breakout do you need/want?
Post by: ian on December 17, 2010, 03:50:53 pm
XC2C32A is only 3v3, but a very cheap and plentiful chip. probably a xc2c256 would be better, so you have enough marcocells to actually do something.
Title: Re: What breakout do you need/want?
Post by: Sjaak on December 17, 2010, 04:12:38 pm
Is 3v3 a problem nowadays?

I don't have a clue what you can do with one macrocell :) It looks like fun to start with cpld though.
Title: Re: What breakout do you need/want?
Post by: ian on December 17, 2010, 06:33:45 pm
I don't think so, but a lot of people still see 5v as a requirement. Bus blaster v1 is 3v3 on,y, as is v2, but that doesn't bother me. I think for the universal logic chip maybe a lot of people want to use it kith arduino and prefer 5volts though. Doesn't matter yo me either way, ibhave both chips already ;)

This post includes free iPadisms :)
Title: Re: What breakout do you need/want?
Post by: Sjaak on December 17, 2010, 09:27:22 pm
Luckilly it has some buffer chips to cope with that ;)

It uses the TXB0108PW buffer chip. That is a bi-directional bufferchip that will convert a low voltage (a-side) to a higher voltage (b-side). the cpld is connected to the a-side (running at 3v3) the remaining at the b-side (3v3 - 5v).

Careful with those, if you happen to have pullup and want to pull it down with the buffer chip, you might not reach the logic 0 voltage limit. I had this problem on one of my board. I was using the MAXxxxx equivalent to this buffer.

[quote author="Sjaak"]You got any cpld particular in mind?[/quote]I'm thinking of a project from the OpenCores site that needs "only" 39 macrocells with register width of 5.  This seems to rule out the XC2C32A, though.

Frankly, I could probably just use the OLS as a platform for doing this with FPGA, but the idea of a breakout board that might plug directly into my DSP board is tempting.

In any case, it should probably be a CPLD/FPGA that is already being purchased in bulk for another Dangerous Prototype.

Q: Does FPGA simply imply hundreds to thousands more cells than CPLD?

[quote author="ian"]
... a lot of people still see 5v as a requirement. ... I think for the universal logic chip maybe a lot of people want to use it kith arduino and prefer 5volts though.[/quote]3.3V is fine with me, too, especially for optical I/O (where the voltage isn't even the point anyway).  I think perhaps 5V is more useful when you want to be able to interface with random other circuits.  If you're doing a single, dedicated design, then it seems like you can just use 3.3V chips for everything and keep it simpler.  In any case, designs which only use 3.3V are far easier to implement on the USB platform.

If you actually need 5V, but you don't have a boost regulator, then the >= 4.01V USB supply will not always meet the 4.75V minimum anyway.  Adding the boost regulator isn't that hard, since some designs only require three capacitors and a single chip, but that does add to the minimum cost.

Well the goal is to make interesting breakout boards :) we don't have a large pile of components nor do we produce our stuff with 1000s a time, so any cheap *) CPLD/FPGA would do the trick..

I guess the ft2232 + cpld is already a kind of 'breakout board' for the xc2c32a, and the logic sniffer is also a 'breakout board'. But personally I like a 'small' footprint for a breakout board. (with fpga there is no such thing as small ;))

*) cheap = a price attractive to hobyists, which is I guess is max 5-10$ for the chips and a little more for sensors.

Definitely! One reason that I only use Sparkfun for their tutorials is because their breakout boards are pricey.
Title: Re: What breakout do you need/want?
Post by: Sjaak on December 18, 2010, 07:11:25 pm
That price is without the actual board, components, headers, manufacturing etc. That will add up to the price.
Title: Re: What breakout do you need/want?
Post by: tayken on December 18, 2010, 07:34:53 pm
Of course it will add. But look at this: The breakout for FT232RL is $14.95 while the IC itself is only $3.95! This is why I say pricey.
Title: Re: What breakout do you need/want?
Post by: ian on December 19, 2010, 10:17:14 am
The ic is four bucks in onside too, they gotta get them between one and two bucks.

imho, if they want to charge their boards a mil they can, they have their own idea on what and why they are doing ... so we might concentrate on "what's missing" rather then "why is spark..."

the 2 major reason ppl get breakboards
 - chips that are hard to solder
 - chips that require a lot of external components

the first one is pretty obvious, and the harder the chip to solder (those legless chips, or micron pitch ones) the more likely is that anyone will decide to go for a breakboard... the second one is also important aspect, it is super cool to have max232+all the caps in smd on a 1x1cm board that you can use to get serial comm to any of your projects in a second ... or a 2A bipolar stepper driver with all the stuff on the board (for e.g. this board, I purchased already more then 20!! and all my friends from reprap project, I think they bought hundreds of those .. even more .. (http://http://www.pololu.com/catalog/product/1201)) or some of the mikroe's boards ... I know why they are expensive (they make them locally and when you phd's soldering your boards they tend to be expensive + export taxes, shipping etc - very expensive in this god forsaken country) but check some of the ones I really like
http://www.mikroe.com/eng/products/view ... eth-board/ (http://www.mikroe.com/eng/products/view/530/mikroeth-board/)
http://www.mikroe.com/eng/products/view ... oto-board/ (http://www.mikroe.com/eng/products/view/475/wifi-proto-board/)
http://www.mikroe.com/eng/products/view ... 32-boards/ (http://www.mikroe.com/eng/products/view/166/max232-boards/)
http://www.mikroe.com/eng/products/view ... t-2-board/ (http://www.mikroe.com/eng/products/view/536/usb-uart-2-board/)
http://www.mikroe.com/eng/products/view ... oto-board/ (http://www.mikroe.com/eng/products/view/198/rtc2-proto-board/)

all of these can be "better" (max232 can be smaller if smd is used and most of others too) and should be made a lot cheaper ..

Post by: sqkybeaver on December 19, 2010, 05:39:52 pm
i have an old radio shack usb to serial cable, it was sitting in a box for the last few years because the drivers did not work in vista/windows7 64 bit, i ended cutting the board out of the cable and started looking up parts. after looking up the prolific chip i realized i could remove the eeprom and use the prolific drivers in win7. it kinda upset me cause all the parts on the board are really cheap.
anyway I'd love to see a sub $10 usb > rs232 adapter. ill prototype it if enough people are interested.
Title: Re: What breakout do you need/want?
Post by: Sjaak on December 19, 2010, 06:18:52 pm
There is a MCP2200 breakout on its way. The MCP2200 is a low cost usb to serial made by Microchip. As a plus it has also some extra GPIO (can be used to drive a couple of status leds).

Here is the link to the datasheet : http://www.microchip.com/wwwproducts/De ... e=en546923 (http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en546923)

how about adding a rs232 converter chip to the bottom of the board?
populating it could be an option for the end user.

I think rs232 is (almost) dead, since every new device has USB and no rs232. Even if a device has serial (like many routers for example) the port is 3V3 or 5V TTL.
Title: Re: What breakout do you need/want?
Post by: ian on December 19, 2010, 08:11:35 pm
We can make a USB to full rs232 for a few bucks if you like, no big deal. That's a super easyroject.

I was planning to design and build myself an OLED breakout board, something good for breadboarding. I have some reference designs but ddn't had time to do any work on them. I can pass on the results to here for prototyping/manufacturing?
Title: Re: What breakout do you need/want?
Post by: ian on December 19, 2010, 08:17:02 pm
It depends on the demand. If it's common parts, and lots of people are interested ( 20) then we can produce it no sweat.

excellent point Sjaak. i guess ill have to keep and old pc around just to use my old kantronics tnc. i guess the only thing keeping it alive are proprietary systems that hide the phy specs. ive seen rs485 used in non standard ways lots of times.

well, it is not "that simple" :D

the reprap machine requires
 - g-code processor
 - 4+1 stepper drivers
 - 1+1+1 heater controllers
 - X aux ports

The first boards were around some small pic and those are not used any more, then there is a whole set of boards that have "each board separately" so you had
 - arduino (initially the smallest one, then sanguino (ATMEGA644P) and now arduino mega) for the "brain"
 - one stepper drive on separate board, initially this was L297+L298, then those pololu alegro boards
 - separate board for extruder (1stepper+1heater) with arduino
all boards linked using RS485 to the "brain" and "brain" linked to PC via rs232->ftdi->usb

There are also few versions of "all on same board" that ppl sell.

There's bunch of places one could by these and prices are more/less ok .. the only 2 boards ppl mostly buy today are the
 - stepper driver lot of ppl go for pololu from link I provided but if for similar price one could pack "better board" (one that would for e.g. allow for both decay control as well as current control, and with proper cooling as these chips heat fast and mounting cooler on the 5x5mm chip ain't simple)
 - extension board for the arduino mega that would take 4 stepper drivers + thermistors + relays or fet's to control heating elements

- there are also few closed source solutions that are irrelevant

What is currently in the "process of being developed" are completely open source stand alone electronics. There are 2 being developed in parallel, on guy (I think south america) is making a ARM CortexM3 version of the original set of boards and he has the pcb making process already agreed somewhere and he is working on the software attm - he will have everything on the single pcb, and there's another set being attm worked on by me and some German guy's that is attm based on "break boards" :D that could/should eventually have a "single board" solution too. Attm it works like this
"UBW32 board is the brain of whole operation (original firmware thrown away of course) is connected to the motherboard (attm this is a solder-less breadboard). Motherboard has only SD card directly on board, and it has sockets for
 - 6 stepper drivers (attm pololu)
 - thermal controller (I have not done this but I believe this will be a small pic with 5 ADC for reading thermistors and 5 digital outputs to control relay/fat's with some pid with a i2c+1 line for communicating with pic32mx - attm I control temperatures directly from pic32 with bang/bang method - no pid)
 - Input module (attm I use 7 buttons, but want to replace 4 of them with a jog, and want to be able to have them on "external board+cable" so I can position them for easy access)
 - Outpit module (attm I use OLED on spi controlled directly from pic32 but the idea is to be able to use different modules so 16x2 or 20x4 char display for e.g.)
 - communication module (ethernet, wifi, bt, xbee .. whatever - some standardized port towards comm module - this is not close to be done)

So the idea is for it to be modular .. but I don't believe the design will be done before and of january ... here you could for e.g. make motherboard + some of the modules, and later a single board solution could be made (with one set of parts just placed on single board) ... but, this all need to be design first... the good thing about the board is that the software is not for reprap only, it executes standard g-code and works as a stand alone printer/milling machine so you can use sd card to place files directly on your computer and do not have any comm between printer and computer, or you can send file via usb (again to sd card) and initiate printing (you can of course move stuff from pc too, control heat etc..).. so the same board can be used for any engraving, milling, cutting machine .. I already tested if it can replace electronics of a "very bad laser cutter" and we successfully cut A3 sheet of acrylic that original board cannot cut (the pattern is too complex and must be split into 2-3 passes with the original pcb) ...

It wasn't my intention to let you stick with old hardware.. Serial ports aren't that common anymore. In my job I see lots of devices that used to be programmed by serial (rs232) move to ethernet or USB. Back in the days when it was still common it was nearly impossible to get a laptop with native (well PCI based :)) serial port and USB convertors were buggy (about 5 years ago). They also gave problems because they occupy high comport numbers (COM5 and up) and that propriatary software couldn't cope with that either.

Luckily those systems move more and more into the future :) (slowly) :)

Post by: sqkybeaver on December 20, 2010, 06:11:07 pm
ideally in 1985 the should have known that usb is the future, but they instead went with a DB25 rs232. it is just a problem for me cause i still use AX.25/packet radio. after 25 years it can still handle current standards. and that is why i still use it!

I already made bunch of them .. I know they are not "complex" to make .. but single channel driver is better as then ppl can use as much as they want (for e.g. mine machines use 5 channels) .. for e.g. A3979 is a nice chip to work with .. not too high pitch but the "Exposed sink pad" is the problem, you must solder the chip to the bottom properly and use vias to move the temp down + you want to add some heat sink on top of the chip ... you want to add small pot for both current and for pfd control...

second very interesting chip is A3985 that require external h-bridge, combining this chip with strong full bridge all properly cooled would be great solution - maybe there are some transistors that are same height as A3985 so a single big heat sink can press them all to make a compact board ...

those are just ideas ... reprap community already have a bunch of boards available... here are some:
- v1.0 (http://http://reprap.org/wiki/Stepper_Motor_Driver_1.0) v1.1 (http://http://reprap.org/wiki/Stepper_Motor_Driver_1.1) v1.2 (http://http://reprap.org/wiki/Stepper_Motor_Driver_1.2) L297+L298
- v2.0 (http://http://reprap.org/wiki/Stepper_Motor_Driver_2.0) v2.1 (http://http://reprap.org/wiki/Stepper_Motor_Driver_2.1) A3977 based, no proper cooling
- v2.2 (http://http://reprap.org/wiki/Stepper_Motor_Driver_2.2) v2.3 [url=http] v2.3 sold by makerbot (http://http://reprap.org/wiki/Stepper_Motor_Driver_2.3) A3982 based, no proper cooling

there's also integrated board that puts everything on the same pcb, stepper drivers are around hitachi chip iirc (http://http://reprap.org/wiki/Generation_6_Electronics) ...

but I can't talk for the "community" ... many things I believed I knew about reprap community came to be false when put to test ... it is very diverse bunch, some try to find solutions that are "ultra cheap" and reliability and quality is second to that, while others require quality above all ...

My 2c :o)

Maybe a full human interface board :oP , well at least few switches, capacity switch (touch switch), few leds, few potentiometers ...

Maybe a cute CPLD board...
I used few time some xilinx xc9572 with pleasure.
My prototypes problems were packaging and number of io pins packaging ...
It should be better than this :oP

Hmm, I think the OLS is better than the DLP Design.  The OLS has just as many I/O pins if you solder headers in every position on the PCB.  Also, I prefer having a PIC for USB on the OLS, because it is more programmable than the FT2232H on the DLP Design.  Even if you want to learn FPGA programming, there still might be tasks that you want to accomplish on a more general purpose CPU, and the PIC makes this easy to manage.  Fortunately, the OLS can make the PIC act in a transparent manner like the FT2232H, or you can write your own firmware for custom applications.

The OLS is not marketed as an FPGA learning tool, but I think that it happens to be a great platform for that - especially given the price.  Now, if I only had time to learn more about FPGA...!

Post by: arhi on January 05, 2011, 03:58:18 pm
yes actually ols is great fpga learning tool ... I kinda like spartan 3A as it don't require eprom but that's not a big deal as you get eprom with ols anyhow :)

I also like to do something with CPLD/FPGA. I don't have experience with both, but I guess a CPLD is better suited for starters. My understanding is they can do the same things only the underlying technology and number of gates differ.

A CPLD has less pins, self contained (no eeprom needed) and some are 5v tolerant (is this still necessary??).

Feel free to correct :)

There is the spartan 3N series which does not need an external prom.  They are more expensive and probably hard to justify the extra cost.   I suspect they are more for secure designs so you cannot intercept the boot stream.

1.A bidirectional logic level converter (for 3.3v <-> 5V logic translation).
2.AD9288 breakout board for use with Open Bench Logic sniffer.
3.Breakout for ARM cortex-M3 chips like LPC1114 and LPC1343.
4.CC2500 like -  RF transceiver breakout board

3.Breakout for ARM cortex-M3 chips like LPC1114 and LPC1343.

We've got a LPC1343 DIP breakout, but it seemed like there were a lot of these already. What did you have in mind? Maybe we can make something unique that stands out.

Yes, I understand there are many LPC1343 breakout boards available. Most of them are over priced. I wanted to make DIP breakout of these inexpensive ARM Cortex M3/M0 .

My design goals were :
1.Free Software drivers -  API compatible with either arduino / mbed.
2.Use Qt Creator as cross-platform IDE with GCC.
3.Provide some 5v Compatible I/Os using cheap N-Mosfets.

I did build a prototype to test if LPC1343 can be flashed with GNU/Linux and Windows(as LPC1343 enumerates as Mass Storage Device). It can be programmed with GNU/Linux  as well with mcopy - I have written a documentation at http://dangerousprototypes.com/docs/LPC ... ootloaders (http://dangerousprototypes.com/docs/LPC_ARM_quick_start#Bootloaders).

NXP provided drivers are not compatible with any free-opensource license. Hence we would have to write everything from scratch. But ATMEL provides BSD/MIT style licensed drivers for their ARM Cortex-M3. Hence I thought it would be better to wait for Atmel SAM3N.

I have a picture of my prototype available at http://garden.seeedstudio.com/index.php ... dBoard.JPG (http://garden.seeedstudio.com/index.php?title=File:UartSBee_as_uCPowerSupplyAndProgPort_BreadBoard.JPG)

with so many arm headers and dev boards (olimex, etteam, mbed, maple ...) I'm not so sure "just header / breakout board" would be very profitable ... and doing a whole kit with examples and tools pre-set ain't a small job .. you get maple from seeed (http://http://www.seeedstudio.com/depot/leaf-maple-cortex-m3-p-670.html?cPath=132_137&zenid=202a0104f898114e0dc527098ca8fac2) for 47$ (with arduino like ide) and imho the best arm dev board (http://http://www.futurlec.com/STM32_Development_Board.shtml) for 40$ from futurlec (made by etteam) .. some "header" solutions from olimex: LPC2103 (http://http://olimex.com/dev/lpc-h2103.html), LPC2106 - DIP (http://http://olimex.com/dev/lpc-h40.html).. also some interesting dev kits from them LPC2919 with 8x1 lcd and sd socket (http://http://olimex.com/dev/lpc-p2919.html), LPC2378 Ethernet, USB, 2x CAN, 2xRS232, ETHERNET, SD/MMC, AUDIO IN-OUT, gfx lcd... (http://http://olimex.com/dev/lpc-2378stk.html), and super cool STM32F103ZE AND 3.2" COLOR LCD WITH TOUCHSCREEN (http://http://olimex.com/dev/stm32-lcd.html) :)

for e.g. something like this last one from olimex (http://http://olimex.com/dev/stm32-lcd.html) but cheaper would be super cool (olimex price is 84EUR) but again, I can't say how profitable will it be, and it would require bunch of examples for different compilers .. (gcc minimum) ..

Registered just to comment on ARM breakout boards.

I would love to see a simple STM32FXXX series breakout board. You can get a STM32VLDiscovery board for around 8 dollars that can act as a cheap SWD programmer, but I've found absolutely zero simple, cheap bare bones breakout boards for the STM32 line of chips that I would feel comfortable buying and putting in a finished project.

olimex boards are ok, but still over priced, 20-30 euros for a simple STM32 breakout board. Plus, the big JTAG header could be replaced by the smaller, SWD.

Would also be nice to buy a bare PCB without the chip on it.

I like that idea! In the meantime though, If you're comfortable with soldering the IC's yourself, you could get one of DP's xQFP breakout boards, solder the ic, and you'd already be halfway there!

I too would be interested in a basic (maybe DIP) ARM breakout board. I figure that when you're ready to move on from the basic AVRs or arduino style, you probably have enough of a project in mind that it makes sense to go for one of the higher end processors - if you don't intend to go in for mass production, it's easier to have the extra resources rather than saving pennies.

Interesting links from Viswesr - the LPC ARMS look easy to program and get started with, and that ultra basic breakout looked good, except not breadboard compatible (full square set of pins).

Perhaps something with a 3v3 regulator and crystal built in (and usb brought out to a connector), and pins spaced DIP style. Should be a decent step up in horsepower and RAM from atmega328/644 (and presumably the hobbyist style PICS?), but also easy to get started with because of the preprogrammed bootloader, and fairly cheap.  Any thoughts?

I'd also second the idea of a logic level translator breakouts - I'll build myself a couple of MAX3000 breakouts when the parts arrive to translate 5V-3v3 for SD card and GPS (currently using 4050s instead), and another for 5V to 1.8v for the more recent accelerometer/compass breakouts (I2C needs bidirectional shifters). Don't know if such design might be a bit too easily duplicated by a hobbyist themselves though to be worth DP's effort.

I think I can post links now, so here's a sort of AVR32 equivalent of the ARM DIP breakout I had in mind and mentioned in the previous post:
http://core.st/projects/AVR32_Starter_Kit/index.html (http://core.st/projects/AVR32_Starter_Kit/index.html)

Micrathene,

It was a general purpose LQFP breakout board similar to http://dangerousprototypes.com/docs/Dan ... _breakouts (http://dangerousprototypes.com/docs/Dangerous_Proto_boards#xQFP_breakouts) , which I got from local store. Unfortunately, I could not get a breadboard compatible xQFP proto board.

There is a N-MOSFET based bidirectional level converter design by Herman Schutte of NXP
(http://ics.nxp.com/support/documents/in ... n97055.pdf (http://ics.nxp.com/support/documents/interface/pdf/an97055.pdf)) . This is a cheap and best solution. It is good for serial buses like I2C. But, can not be used for pulled-up / pulled-down ports pins.

Ian,

We could also have xQFP proto-boards compatible with breadboard(DIP).

I'm not really sure of everything you're saying here, so no offense if I read it wrong.  On the one hand, there seems to be an implication that ARM is higher end than AVR.  But you also seem to imply that PIC is 'hobbyist' compared to ATmega.  On the other hand, you could be lumping only some of the PIC options in with some of the AVR options.

In any case, I just wanted to jump in and point out that AVR and PIC both have "high end" processors that would compete well with ARM.  You won't find these 32-bit processors on an Arduino (yet?), but it doesn't mean Atmel and Microchip don't have evaluation boards that would be just as useful.

A custom USB Device would be a decent mid-level project for some folks, but the Arduino is fairly crippled for this.  They're only just now getting around to using the better AVR chips with built-in USB, but they still haven't put out a single-chip USB AVR board.  There are PIC platforms which are thus a step up from Arduino in this respect because they at least have USB that can do something besides emulate a serial port.  I also agree that the preprogrammed bootloader available in some AVR chips makes them potentially much easier to get started, and so I'd say it would be great to have an affordable Dangerous Prototypes board based on an AVR with built-in USB, including the Atmel USB bootloader.

L6470 (http://http://www.st.com/internet/analog/product/248592.jsp) - 8$ 1/128 spi stepper driver

I'd reeeeeally like to see a simple breakout board with it, possibly with a way to easy attach a heat sink to the chip (or with a big heat sink already mounted). With r.m.s. current 3A and Rds of 0R5 (worst case) the dissipation is 4.5W per mosfet, and as this baby does 1/128 microstepping you need to calculate all 4 being used in the same time so 18W of heat needs to be "removed" from this baby. So either some good "glue on" heat sink or screw holes on board to allow one to be attached easily.

Hirose connectors (10-pin DF23C specifically, for Nokia LCDs). I found a European company that sold breakouts for these at one point, but it looks like they did a run or two of them, and then gave up. :( (I'd link to it, but I suspect the anti-spam filter would prevent me on my first post.)

Thanks for the suggestion logic,

I'm sorry about the aggressive spam filter, you should be out of its grasp already (or very shortly).

This shouldn't be a problem, and is something we could make quite quickly. How would you envision the board? Just a LCD-sized PCB with pin breakouts? Or more a complete thing like SparkFun has with a power supply for the back light too?

We actually have a Nokia LCD backpack coming out very soon, but it has a PIC to provide USB control and isn't a breakout:

now wrt that backpack project - why is not anything from the pic exposed to the world? at least 2 digital pins for software serial communication...

We are getting much better about the breakout on new projects, but this is actually quite old and has been sitting waiting for a compatiable LCD supply for a long time (found one a few weeks ago). Any V2 will have all the pins on a breakout.

You can use PPS on this PIC to assign a serial UART to the ICSP header pins, so all is not totally lost :)

In my very limited experience the HC-49U is usually 3x cheaper than the cheapest "bar" type SMD crystals ($1.10-$1.40 : $0.30-$0.50). It's pretty frustrating, and we try to use the cheaper one when possible. Would of course prefer a cheaper, smaller version :)

I'd honestly be ecstatic with something as simple as this, perhaps with a PCB sized to carry the screen (or not, I just don't want to solder those connectors *grin*):

(That's what I was going to link to originally.) The Sparkfun board (http://http://www.sparkfun.com/products/8600) is quite a bit more than what I was looking for; I don't need buttons or status LEDs, and the footprint is much larger than the space I'd like to fit it in.

(What I'd really love is a color OLED display (http://http://www.sparkfun.com/products/9678) in roughly the same footprint, but Sparkfun seems to think people want to build a mobile phone out of it, given the size of their carrier board (http://http://www.sparkfun.com/products/9676)...).

I wouldn't complain about a backlight driver, 3v3 regulation, and hey, why not even 5V logic shifting on-board, as long as it all tucks behind the screen. But, that's all a luxury for me. :)

The great problem is getting working software to make that chips worth their value.
I have the source code for the XMega eval board of the MPU3000 and I cant understand, it was sourced by an insider at Invensense and I was hopping that I could port it to Arduino/atmega328p as those are a common micro-controller in the simpler tri and quad copters, the problem is that the code is super complex, and the compiled output as an whopping 64Kbytes!!!
The initialization and configuration of the MPU3000 alone and the special data that is sent to it so it can talk to external accelerometers is in a source file with more than 10K of code with very little comments.

If some one could get open-source drivers it would be a great chip as they are pretty cheap but its almost impossible do to anything with them.

Oooh, I like this. I've been thinking about screen-ifying some random objects around my desk, kinda like Sparkfun's old Sinister7 project (http://http://www.sparkfun.com/tutorials/39), this would make it quick and easy.

One request though: Could you please route the USB pinouts to an unused header footprint in addition to the built-in connector? That would make it easier to solder on a USB cable pigtail to route it out the back of said random object. (Plugging a normal cable in would be too tight, it would stick out too far.)

Cool design! The chip is great but if you use pullups it has some issue detecting the direction of the signals.

BTW does someone know how to design a board like this on eagle? or is it just  a regular pin cut in half with the board dimension? and how do you cope with  tolerances during the fab fase?
Title: Re: What breakout do you need/want?
Post by: tayken on May 29, 2011, 09:14:06 pm
Yeah, pull-ups create problems so I2C is not possible IMO. But the problem is related to auto-direction sensing, there should be some other ICs out there with manual direction control, which can be used with pull-up resistors and I2C.

One other reason was to show the design of the board for future breakout board designs. What I would do to create them would be to run the edge of the board through the middle of the header.This pdf (http://http://akizukidenshi.com/download/ae-llcnv8-plot.pdf) is the board layout for manufacturing.

This is an old thread but i think it would be useful to suggest that breakouts for 2-3 common FPC/FCC connectors would be great. As far as i have seen, 10 pin is common and would be great to have since most LCDs and this: www.mouser.com/ProductDetail/Sharp-Micr ... kDyw%3D%3D (http://www.mouser.com/ProductDetail/Sharp-Microelectronics/LS013B4DN02/?qs=3olo1ghYtVS1juvmMEkDyw%3D%3D) . Other than a 10 pin connector, i can't think of other common pinouts but different sizes of 10 may be more useful.

If I had a USB to Serial breakout, I would want it with either screwterminal strips, binding posts, or header pins (or all of the above, wired in paralell). These connectors would already be attached  and (unlike most other breakout boards of this type) would therefore require NO SOLDERING on the part of the end user.

Furthermore, there should be a total of 10 such connectors:
Shield ground
Signal ground
Carrier detect
Transmit
Receive
DTR
DSR
RTS
CTS
Ring indicator

(most manufacturers break out only the 4 or 5 most commonly used of these pins, and the rest are inaccessable to the end user)

Also, ALL settings commonly found in hyperterminal software should be available:
1, 1.5, or 2 stopbits
5, 7, or 8 databits
no, odd, even, mark, or space parity
no, hardware, or software handshaking
Baudrate selectable between: 110, 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400, 460800, 921600

(most manufacturers use chips that support a few of these features being settable, in software like hyper terminal, but I want your design to have ALL of these parameters to be user-settable).

iirc FOCA v2.1 from IteadStudio (http://http://iteadstudio.com/store/index.php?main_page=product_info&cPath=18&products_id=94) breaks out all pins from ftdi chip. As for the settings in hyperterminal, it has little to do with chip. baudrates below 600bps are unsuported since 286 pc's with dual serial port driver in one chip (can't remember the marking), all other bps you can select on ftdi chip if your driver supports it, I can select 600-921600 on any ftdi chip on linux system, same with databit and parity and handshake ..

anyhow, ftdi RL chip is a standard soic, you take any soic to pdip adapter and you have breakboard for ftdi, just add on usb connector :)

I mean you don't need to depend on an existing ftdi chip, why not just make your own custom "all features that ever were available on any serial port in the history of the 9-pin serial port on computers, are now available on this USB to serial converter" type of USB to serial converter chip. You have a silicon chip factory on the premeces of your company right? You can program the silicon shaping robots at the factory to build any type of chip you need right?

Cause you see I need to be able to access the FULL possible range of speeds that have ever existed on a serial port, down to and including 110baud. And I need all of the other features too. You see I can't have one USB converter that has one sub set of the serial featrures, and anothe USB converter that has another subset of the serial features. I need one USB to serial converter that is full-spec, that is that it supports EVERYTHING that a 9-pin serial port has ever been capable of handling in any comptuter. Newer serial ports dont' do low speed, older ports don't support the higher speeds. But I need a USB to Serial converter that supports the FULL range of speeds that have ever been supported on any serial port, and I need it to be a single device, so I don't have to switch between converters when switching between speeds. And it also must support ALL 9 PINS, not just 1 RX line, 1 TX line, and not even 1TX line 1 RX line 1 other output 1 other input. I need one that supports ALL 9 pins.

'cause it would be expensive and one could sell 100pcs max ... so not really something interesting for mass production.
furthermore ther's http://www.ftdichip.com/Products/Modules/USBRSxxx.htm (http://www.ftdichip.com/Products/Modules/USBRSxxx.htm) that breaks out full db9 connector...

Now, even with FULL support of ALL pins you still can't use this serial port as a legacy serial port (and hack it to be programmer etc etc) cause all those apps did not use it as serial port but were talking directly to the usart chip. Since there's no usart chip here (especially not on port & interrupt those apps know how to use) it will not work

even if someone work in silicon chip factory what would one do with hundreds of thousands of usb2serial chips that are too expensive?!

That is operating system/drivers problem. You can't do it on windows for e.g.
What you need is a separate device running serial ports, talking to your "whatever you talk with" and then sending data to PC via usb.

I'd like a Xilinx Zynq FPGA with 1gb of ram Breakout for $20 :D

Xilinx FPGA's are too mainstream, we can churn our own FPGAs in our facilities. Better, faster and dirt cheap!

You r right, forgot about that, I'll hold the silicon wafer while you burn it with a laser pointer :)
P.S. forgot about the curveture of the earth, no way you can hit it from Japan to Serbia, guess we'll just have to bounce it of one of our satellites

But would it be possible with an Zynq breakout? (not for $20 of course)

Only fpga breakout I have found so far is this, but spartan 3:
sparkfun product: 8458 (Why can't I enter any url?)
The Papilio is a bit easier to start with instead of that, but an breakout with all io avilable would be interresting, but I guess, an BGA would be monstrous?

Hey neslekkim, the url problem is an anti-spam thingy. You'll be able to enter links in about 24 hrs.

BGA is really hard for companies like DP. They need multilayer boards (at least 4 layers) to be able to route the signals, cannot solder prototypes by hand, and testing needs special equipment.

If Spartan 6 is enough to satisfy your hunger, I suggest Avnet LX9 Microboard.

Then I probably would wait for an papilio with spartan 6, atleast an papilio have io pins, the avnet board doesn seem to have lot of io.
The sparfun breakout that I tried to link to, have more io than anything, every pin is broken out, so even that would be good..

So, I guess my quest have to end there, Papilio Plus, or Sparkfun breakout. oh, well.

this might be a cool one in the category of sensors. 15cm proximity sensor, designed for cell phones, but might have other cool applications for jack-in-the box like toys, small robots, security alarms.....  It is really cheap, i2c interface, but in a PIA package.

What about a 16f/18f  pic break out board?
