AMG I am using pin 0 and 1 for SDA and clk
The pins in the .overlay refer to the processor pin designations. I believe I already assigned them in the default board definition. You can search for
circuitdojo_feather_nrf9160_common.dts and that should have everything. (Look specifically at I2C1)
The I2C pins (D0 and D1) should be defined as:
sda-pin = <26>;
scl-pin = <27>;
If you use other pins on the board, you’ll need to remove/disable I2C1. You’ll also need external pull-ups.
AMG Also I couldn’t find the pin layout for the feather board v1 only found for v2. Can the analog (A) pins be used as digital ?
Pin layout is the same. Yes, analog pins can be used as digital. Not all digital pins are analog though. 😉
