He he, I think the collision is only in my head. Well, Sebastien wanted to remap the SPI2 pins on pins used by the RTC clock.and Boot LED...
I considered these: - RP17, RP18 are occupied by RX1, TX1 - RP4 is RTC out - RP7, RP8 is I2C1 - RP9, RP10 are part of ICSP connector - RP11, RP12 are RTC clock - RP13 is Boot LED (RC2) <-- other boards compatibility. I also was conditioned by the some rules from my board (and Arduino pinout "rules"): - it is nice to have contiguous pins on extension connector for at least half of a Port. (not shared with I2C, SPI, Serial) - good to use it on LCD's by example, - on old 19Fs you have to have some kind of order on ADC pins, because are dependent of each other (well, not applicable here where ADC pins are independent) Also I had/have some unclear things: - you said RTC Out pulse pin is optional. That mean I can disable it without loosing RTC feature? - when you remap pins for SPI2, it needs to be in order (RP1, RP2, RP3, etc.), or can be selected random? What ever is selected here on 28pin device, it propagates on the 44pin one. Vasi P.S. Well, pinout compatibility was until now only FreeJALduino and Pinguino boards care. But it will be nice also for Jaluino family.
