Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

If it's been posted, I didn't note it. I'm looking for a chart or spreadsheet listing the GPIO pin names and/or numbers for the 20x2 40-pin GPIO connector. Something which supplements these:



I'm trying to replicate something like what I'm using for a GPIO PCB for the F4:



I have a vague recollection that something like this has been posted, but I can't find it.

I posted this during the discussion on joysticks. I can upload it as a doc or spreadsheet if it is of any use?

Thanks, Bill and Peter. I'm pretty sure I had something like Bill's posting in spreadsheet format, and that was what I used to produce the provisional F4 layout, but I can't find it. I2C, SPI, COM1 and COM2 are in the same place, but there were fewer ADC available on the F4, and I don't think I was able to get all the PWMs.

I'll use that as a template with Peter's master and will post the spreadsheet doc.

It will be candidate for CMM2.fun entry...

Here's a shot of the spreadsheet with the pin names. Since I've been working with the F4, I had forgotten that the CMM2 pin numbers are the same as the 20x2 connector pin numbers.



Here's a video of LEDs being lit off of BigMic's 20x2 slim breadboard PCB:

CMM2 LEDs

Here's the program:

' t_leds.bas
dim integer i,j,k,p(15)=(0,3,5,7,11,13,15,19,21,23,27,29,31,33,35,37) ' CMM2 odd row
dim p2(13)=(0,8,10,12,16,18,22,24,26,28,32,36,38,40) ' CMM2 even row
for i=1 to 15: setpin p(i),dout: next: for i=1 to 13: setpin p2(i),dout: next
do
 for i=1 to 15: pin(p(i))=1: ?p(i);" ";: pause 1000: next
 for i=1 to 13: pin(p2(i))=1: ?p2(i);" ";: pause 1000: next:
 for i=1 to 15: pin(p(i))=0: next:for i=1 to 13: pin(p2(i))=0: next
loop

Pins 37 and 18 are omitted because I ran out of LEDs. 22 LEDs are lit.

I haven't yet tried the SPI, I2C, PWM, COM, count, etc. functions.

Jiri--I've got a ways to go before I get there, including a re-do of a PCB, but will be happy to post to your site when I have a finished product.
