I am trying to get interrupts for buttons using Arduino for the BLE Nano2 nRF52832. There doesn’t see to be any example that works. Are interrupts possible for the nano2 using Arduino?
The nRF52 can also trigger on input pin H/L transitions, but it can miss transitions when the chip is handling BLE functions.
My code base suggests using pin comparator with a ½ Vdd reference instead.
