On my custom board I have a button BUTTON_1 in between supply voltage (Vbatt = 3V) and input on nRF52832 - therefore input will receive 3 Volts directly.
I have configured...
Hi,
I am developing a code in which, among other things, when a button is pressed, a led turns on. In the same button handler, a timer is started to turn the led off a bit...
