The mapping I found looks quite different (PCB v2.0 and PCB v2.1):seaton wrote:Pins found so Far with board marked Felix 2.0: (will update this post as I identify them) [...]
OPT1-1 = µc42 = fw42 = PL7: Available for I/O.
OPT1-2 = µc51 = PG0: Used for SD card.
OPT1-3 = µc41 = fw43 = PL6: Available for I/O.
OPT1-4 = µc39 = fw45 = PL4: Available for I/O.
OPT1-5 = µc37 = fw47 = PL2: Available for I/O.
OPT1-6 = µc30 = RESET: Not useful as I/O.
OPT2-1 = VCC
OPT2-2 = VCC
OPT2-3 = µc39 = fw45 = PL4: Available for I/O (same as OPT1-4)
OPT2-4 = µc51 = PG0: Used for SD card (same as OPT1-2).
OPT2-5 = GND
OPT2-6 = GND
Naming convention used above:
* OPT?-?: Header pins as indicated on the PCB.
* µc??: Pin numbers of the µ-controler chip.
* fw??: Pin numbers used in the Repetier firmware (see fastio.h for the mapping between µc?? and fw??).
* P??: ATMEL identifier for the port/bit within the µ-controler.
So the fw?? pin numbers are the ones you would use in the firmware's config file. Note that µc42=fw42 - so you can never go wrong with 42, which we knew already beforehand
