Hello all,
Sorry if this is foolish question, but I'm having a lot more trouble doing this than I expected
Basically, I have a Raspberry Pi Zero running OpenWRT 19.07.3 and I want to add an on-off switch with the GPIO pins. Following this I managed to see the state of the switch and all that; however, I do not know the next step to using it in OpenWRT.
Looking at the relating documents about adding buttons, they seem to all expect your button to be named in the system, whereas doing cat /sys/kernel/debug/gpio
would show my added switch simply as "sysfs
".
At this point I think that I have to change the .dtb
file; however, I cannot find where to modify this in the source.
Thanks for any help!
