[quote author="jayb1239"]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)[/quote]
Glad to hear you got it up and running, smooth sailing from here on, I hope..
[quote author="acooks"]I'm wondering if anyone has tried to implement the EHCI debug device class using a BP? Most modern PCs don't have "serial ports" anymore, but usually provide a USB debug port that can be used for debugging both Linux and Windows kernels.
I'll post relevant links when the spam protection allows it.[/quote]
Welcome to the forum. Not that I am aware, no one has tried this yet. It is interesting, pleas do post..
Hi Nataly, welcome to the forum. unfortunately no. the current firmware starts reading the frequency as soon as you type in the f command. It was designed to read continuous sources.. But we might add a feature enabling this in the future, but this might be some time in the future... something like adding an external trigger to start/end the read... but like I said it might be some time in the future..
Whaaa, where are you reading 1v? with the PES51, I was getting a short between the thermocouple and heater, but I thought it was a blown heater, IT could be a design thing, i guess. Sorry for being a guinea pig. I still can't get my SiD to work, as programing the 2550 seems to be impossible for my pickit3... I'll get a replacement chip next week and try it out..
[quote author="dtmf"]Who know what is the best PID settings for soldering iron with thermocouple?
Hakko 907 work Ok, but other with thermocouple like weller pes 51; some China ZD irons; Ya Xun , works with +- 10 C instability.[/quote]
are you speaking of PID instability or is the temp sensor reading the wrong temp? In any case it doesn't realy matter. I was similarly opsesed with tip temperature stability, but then I found out that the tip temperature drops like 50C during soldering, and even the best soldering iron's in the world take a long time to recover.. IMO +-10c is just fine even for professional soldering environments...
P.S. regarding the PID tuning, there are algoritams on line on how to tune PIDs for heated bodies.. it involves suting two parameters down, tuning the one, then once you got that one the way you want it, you start tuning the second one, and finaly the third.. I believe the order is P then D then I....
Hi, I'm very sorry about this, but the only thing I came up with was that the power might not be sufficient, but if the voltage doesn't drop below 3V your fine...
This is probably and issue with the flashrom software, or the ROM itself. I would advise you to contact them and point them to this thread, or send them the info you've colected. From what I can tell the Bus Pirate functions fine.. I'm sorry you wasted so much time on this. http://flashrom.org/Flashrom
mobo is the motherboard (sorry for the shortening)..
yes the Vcc pin is the power pin..
read the voltage there, while you are programing the chip as you have been from the start.
Report back and we'll take it from there.
Can you take a pic of your setup.. how you've been programing till now, this should help us to avoid any miss understanigs, and would be easy for me to draw on it to guide you, If I figure it out that is..
[quote author="seyk"]are you able to tell me which part is probably broken?[/quote]
from the self test, either a soldering issue with the board, or the MISO pin of the microcontroller is fired... Can you check the soldering, around the MISO pin, pin 16 of the PIC24FJ If not, you can contact Seeed about a replacement, point out this thread to them as reference..
To check the voltage of the chip , you need to attach the black leed to the center tap (COM) on your voltmeter, and the RED to the right (mAVO)..
next turn the knob to the right to 20V.. connect the black lead to your mobos power supplies GND black wire. use the red lead to touch the FLASH ROM ICs power pin, check datasheet which pin is for power...
this should be 3.3v..
P.S> I notice that you keep running the tests and connections with the power supplies off. If you are trying to connect to a device that is being powered by the BUS pirate you need to turn the power supplies on, otherwise the data pins will start powering the device through the pin protections, and you could fry the BP pins, and or the ROM..
needed connections for Bus pirate powered flashing.. 3.3V IO to the FLASH power pin, GND to computer power suppliy GND (black wire) .. and the normal SPI connnections.. (this mode requires that the Power supplies be turned on 'W' command
IF you want to use the mobo to power the flash, you just disconnect the 3.3V IO... hhere there is no need for the 'W' command..
