Pins supporting OneWire
-
I am designing a custom board for the LoPy4 and I was wondering which pins can support OneWire. Is there any limitation apart from the pins already assigned (e.g. LoRa module, UART, etc). Any requirement?
Thank you in advance! -
@berni You can use any digital bidirectional (i.e. non analogue input only) pin which is not allocated to another functionality. This means you should avoid:
- P13-P18 since they are input-only pins,
- P12 which is used for antenna selection,
- P5-P7 which are used for LoRa radio, and
- P0-P1 used for UART.
