Hi all,
I have created a custom board file for my pcb that uses the nRF52832 (rigado module). I have 10 buttons attached to the board and am successfully reading a button press on all (using BSP). It also nicely handles the BLE advertising and sleep features and the debouncing of course.
How can I detect the button release in the bsp_event_handler below? My goal is to set a bit in m_custom_value[2] which corresponds to a button. If the button is held down, the value won't change, however, when the button is released (upon detecting the release event) the value will be reset.
Kind Regards,
Zoran
m_custom_value[2] is initialized to 0xFF
