The photon/P1 supports many different pin functions on the same pin. Like the TX,RX pin, how can we change the pin functions to switch between digital GPIO, ADC input or PWM? Also the P1 has reserved pins. Is there any plan in the firmware to define/use these pins like any of the other pins? Thank…

@peekay123 , LOL yeah, git clone https://github.com/spark/firmware.git

@wesner0019 , that will clone the main branch, not develop! You need to specify the branch with: git clone -b develop https://github.com/spark/firmware.git :smile:

We should coordinate with Satish so the functionality on those pins aligns with that of the extra Electron pins. If we make 'em C0-C5 then those pin capabilities should line up. Remember that B0-B5 will also be available, and those pin capabilities may line up better- no idea at this point.

@peekay123 , Got it make but get an error at the end. Used: make PLATFORM=photon, actually i should have used: make PLATFORM=P1 [image]

Looks like you’re missing the stat command. You can install that with MinGW.

@mdma is right and you also need to make and flash the system firmware first from the “modules” directory. :smile:

@Dick @satishgn Hmm, that would be awexome if they could line up perfectly… but since we are sweeping up the “extra” pins of both systems… it’s highly unlikely that the same port pins (and therefor same functionality) would overlap. Because of this, perhaps a separate naming scheme would be best. …

@mdma , i just installed the MinGW, show do I install a stat command? Noob at this whole process. @peekay123 , I am trying to follow the https://github.com/spark/firmware/tree/develop directions but there seems to be some gaps that need to be also like you just pointed out. so I would change directo…

P10-P15 might be a bit confusing, read P ten and P fifteen. P00-P05 might be read P zero and P five. P20-P25 might be read P twenty and P twenty five. Perhaps P1S0-P1S5 may work better, P0S0-P0S5, P2S0-P2S5, read P1, S0-S5, P0 S0-S5, P2 S0-S5, etc. S could stand for spare :stuck_out_tongue: or “…

I originally thought S0-S5 as well, but then different platforms with different spare pin functionality would be confusing to have S0 on both platforms. It might come down to what seems to be the shortest, unique and future proof way to define spare pins for the system. Those 3 don’t really make t…

Sorry @wesner0019 I got absolutely slammed and didn’t get to this yet. That said I have it prioritized on this sprint which starts tomorrow
