Hi, I was having trouble driving pin P0.30 as an output on the nRF9160 Feather and I discovered a mismatch between the schematic and device tree. So on the schematic, INT1 is connected to P0.30 through a normally closed jumper, and INT2 is “connected” to P0.29 through a normally open jumper. However, in the device tree definition, P0.29 is defined as the interrupt source for the lis2dh:
irq-gpios = <&gpio0 29 GPIO_ACTIVE_HIGH>;
This was confusing for me as I was trying to drive P0.30 as a GPIO output as it shows up as unallocated in the Nordic device tree visulaizer thing, However I could only drive it to 70mV since as I later found out, it is by default physically connected to the INT1 pin of the lis2dh.
