ARDUINO_DUE_PAPA section, pin missing

[ik1whn]

File IODue.cpp, section:
#if defined(ARDUINO_DUE_PAPA)

these lines are missing:
#define PIN_DSTAR 9
#define PIN_DMR 8
#define PIN_YSF 7
#define PIN_P25 6

[phl0]

Pins 7 and 8 will collide with what is already defined:

#define PIN_COS                7
#define PIN_PTT                8

[ik1whn]

Ok but without defining the pin arduino ide exit with error
exit status 1
'PIN_DSTAR' was not declared in this scope

[phl0]

Yes sure. But the question is which pins to use for these. I don't have the Papa board pinout to see which ones would be free to use. Is there a schematic or pic from the papa board?

[ik1whn]

You can use pin 4 and 5 instead of 7 and 8
pin 3, 4, 5, 6 and 9 are free

[phl0]

I made a change based on the pin numbers you mentioned. Could you please give the code from my dev branch a try: https://github.com/phl0/MMDVM/tree/fixPAPA?files=1 If that works correctly I will make a pull request to the official code.

Btw: Could you make a photo of the PAPA board? Did a Google search yesterday but could not find anything ... Would be interested in the hardware.

Thanks Florian,
I try it probably tomorrow, today I'm gone.
The Papa board is the firts board for mmdvm, It is a prototype derived from
a gmsk d-star board realized by Jim ki6zum.
Here someone still uses it but rarely update the system.
I send you a photo and schematic of the modification of original gmsk board.

Die you actually test the mode pins? Or did you just compile it?

[ik1whn]

Arduino programmed and operationally tested, tx-rx dmr mode is ok. I can
not test mode pins now because the system is remotely.

Okay. I guess they are rarely used anyway. So I think we can close this issue then.
