Bus Pirate Development / Re: Bus Pirate V4 LCD HD44780
I did have a look at the code in HD44780.c but I'm quite new to coding and the majority of it went over my head so I thought it best to ask if it was on anybody's to do list. I noticed some people mentioning that the BP v3 LCD Adapter works with the BPv4, but also that there were passive adapter designs for the v4. It just seems to make more sense to me to be able to use the Bus Pirate with minimal external accessories.

Bus Pirate Development / Bus Pirate V4 LCD HD44780
Hi, Is anybody working on getting LCD mode working on the Bus Pirate V4? As the V4 no longer requires the shift register due to the extra I/O's available.

Bus Pirate Development / Re: Compiling from source
You can leave it in if its helpful for you, I know what to look for now and others having the same issue will find this thread to tell them what it is.

Thanks again for all the help

Bus Pirate Development / Re: Compiling from source
I have tried building with MPLAB & MPLAB X with all projects in there (the MPLAB x project, the BusPirate project and the BPv4 project. The hex flashes fine, but the bus pirate isnt enumerated when plugging back in :-(

Bus Pirate Development / Compiling from source
Hi,
I wonder if somebody could provide a little assistance.

I am trying to compile the BPv4 firmware from source.

I cloned the SVN and opened up the project in MPLAB 8, I then modified the base.h and commented out the v3 (tried with and without comment) and then tried to make.

The build reports to go successfully and I get a hex in the output dir which is 339kb or if I export using the default end I get a file of 962kb but flashing either of these via pirate-loader does not work. The pirate-loader reports success but the bus pirate does not boot.

This is probably something silly that I am overlooking but from my reading around the forums and trying to find a solution myself I am getting nowhere.

Any suggestions

Thanks in advance

Bus Pirate Support / Re: BP v4c IC3 I2C EEPROM problem
And now its working... Nothing changed other than I enabled/disabled pullup & powered VPU & enabled Power Supplies. Then it works, but as well now it works without all of that being toggled. Ah well at least I know my other EEPROM is likely good and can be used on build no 2

Bus Pirate Support / BP v4c IC3 I2C EEPROM problem
Hi,

I now have my Bus Pirate V4c built and programmed, not tested it out properly yet other than running the Self Test which is below.

When trying to use the onboard I2C EEPROM to try and have a play around with it I get

Code: [Select]
Searching I2C address space. Found devices at: 
Warning: *Short or no pull-up

And I notice in the Self Test, although there are no reported errors it does not say OK at the side of EEPROM. I have inspected my soldering and all seems well with no shorts. The 2x Resistors (R9-R8) test fine at 2k and the Capacitor C6 appears ok. The EEPROM is an 24AA64 from Microchip http://ww1.microchip.com/downloads/en/d ... 21189r.pdf.

Does anyone have any suggestions or is it just likely to be a DOA part?

Bus Pirate Support / Re: Chicken & Egg - BP v4c Programming?
All programmed using the MSP430 Launchpad. The wave of joy that came over me when self test reported everything ok was unbelievable. Due to one thing or another this build had been delayed and has taken around a month to complete (3 weeks waiting for a lost package from Microchip)

Bus Pirate Support / Re: Chicken & Egg - BP v4c Programming?
Thanks for your reply. I will see what today's post brings.
Although I do plan to do future work with PIC, it isn't enough to justify a pickit as hopefully I will manage with the BusPirate.

Thanks again

Bus Pirate Support / Chicken & Egg - BP v4c Programming?
Hi all,

Just completed a BusPirate v4c build and am now met with the issue of programming it. I own no pic programmer :-( I could build something, but I did take the easier option and chose to replicate the ApProg430 (the developer escapes me) and have ordered the MSP430 Launchpad for this purpose. As expected knowing the UK postal service it didn't arrive today as it was supposed to and I'm impatient.

I would like to try out my new (and first) BP, but worst case scenario I can wait for the Launchpad to arrive.

I read in the forum mentions of using an FT232R to bitbang the programming using PiratePICProg but couldn't find any details or even if this is possible. (I have FT232R available)

I have tried to use the GoodFET with their PIC application, (doesn't fully support 24F, designed for 24H) and this will read the Chip ID and act like it is flashing the bootloader to the BP but this goes on forever and doesn't actually write anything. It does allow me to write / read memory addresses though.

At my disposal I have the GoodFET, a TI MSP430 FET, a Stellaris Launchpad, an Arduino, FT232RL (will be salvaged from the GoodFET, well probably I will cut traces to the MSP430 and keep it on the board by soldering to relevant pins if needed)

I have quite good soldering skills, but a low selection of components at my disposal. I also only have basic experience at programming for the Arduino / Stellaris so porting existing solutions is out of the question.

Any suggestions or do I just wait for delivery?

Thanks in advance

Bus Pirate Support / Re: BusPirate 4v2 - Sick of Beige
Did you manage to post out my order schazamp? Sorry if I missed any PM's from you, I only created an account last week to message you and order, but didnt realise that if I failed to post within 24 hours then my account would be removed by the spam filters. So I have had to re-create my account.

Thanks
