Wire1 not working in revG

[DanKoloff]

Refer to this: https://www.olimex.com/Products/IoT/ESP32/ESP32-GATEWAY/resources/ESP32-GATEWAY-GPIOs-Rev.F-up.pdf and also refer to the schematic.

I would avoid pins 16 and 17 since they are used for the Ethernet chip. No matter if you have cable attached the pins are in use.

Notice that GPI35 and GPI36 and GPI39 are only inputs for the board (hence why are they named GPI instead of GPIO).

Use GPIO4, GPIO12, GPIO13, GPIO32, GPI35, GPI36, GPI39.

Hi,

Thanks for your help, I didn't see these pins was just inputs :o

I'll check that in a moment,

@DanKoloff Hey,

I just tested the pins (4 , 12), (12, 13) and (32, 33), and it didn't work :/

Not at the same time right? Since GPIO12 is mentioned two times once as SDA once as SCL and also GPIO33 is not free.
