Looking at P1 datasheet http://docs.particle.io/photon/p1-datasheet/
Section: 3.3 PIN OUT DIAGRAMS
Pin A0 listed as pin 54 of P1
Later in section: 3.4 COMPLETE P1 MODULE PIN LISTING
we see:
50 MICRO_GPIO_14 PC5 A0
…
54 MICRO_JTAG_TMS PA13 D7
Going back to 3.3 PIN OUT DIAGRAMS
There is no info on pin #50
If pin 54 can’t play as ADC then I just received a batch of pretty PCB souvenirs…
@sparkly, pretty sure its just a documentation error. I’m running my touch screen using A0 as one of the ADC’s and the screen is working as it should.
Yes that is an error, sorry about that! A0 is pin 50. I have that and other errors documented here (errata if you will): https://github.com/spark/docs/issues/19
Hi, all. Terribly sorry about all of that. These datasheets have been removed from the docs site. They will return, rising like a phoenix from the ashes, when we deem them error-free.
@sparkly, I’m sending you a PM to see what we can do to help out with that PCB problem.
Bumping this topic rather than starting a new one,
Is there a Pin Map for the GPIO for the P1 ?
My eagle symbol doesn’t seem to match the calls I need to make.
( Using the 0.4.3 build environment. )
Can you explain more what you are trying to do?
Toggle some pins, just using the pinMode() and digitalWrite() for now.
Pin map index number I have to call doesn’t match the names in stm32f2xx/pinmap_hal.c
For example I’m trying to toggle P1 pin 45 (named GPIO_7 on the eagle symbol), after some experimentation I found using pinMode(2, x ) & digitalWrite(2, y ) worked even though 2 is listed as GPIO_5 in the pinmap_hal.c file. The same is true for other pins listed as GPIO.
Since the P1 datasheet is down at the moment, I thought I’d ask here if anyone knows where I could find the info.
Hi @jakeypoo! We expect the P1 datasheet to come back online on Monday. In the meantime…
Pin 45 is D2. Therefore
pinMode(D2, OUTPUT); digitalWrite(D2, !digitalRead(D2));
should toggle it.
