BTNPIN compile time option sets unused buttons to GPIO 0

Question

robertvb83 opened this issue a month ago · comments

Setting 4 buttons works as expected (buttons GPIO are only set but still disabled) -D BTNPIN=0,4,34,35

However if you set less than 4 buttons, the remaining buttons are set to GPIO 0 automatically. Leading to double entries for 0
-D BTNPIN=0,4

See above

Set other buttons to "unused"

Just define BTNPIN=0,4,-1,-1
You can also set BTNTYPE if you wish.

thank you, that is, what i was looking for.

how is BTNTYPE set? i use 2 push buttons and 1 analog potentiometer, 4th button should be GPIO35 but disabled by default

BTNPIN=0,4,34,35
BTNTYPE = PUSH, PUSH, ANALOG, -1

Check const.h for button types.

Check const.h for button types.

Thanks for pointing me in that direction. It works exactly as it should
