Hello @rin9147

no, you can but you don't need to remove the pullup resistor. If you read GPIO32 like this it will report HIGH and when you connect GPIO32 to GND with a wire is should read LOW. Use below code to set GPIO32 as input and do something when it is read LOW.

pinMode(32, INPUT); if(digitalRead(32) == LOW) ...

Thanks

I set it up based on what you said and it works.

I noticed later that m5-docs had the same thing.
I'm glad you explained it in detail. Thanks.
