https://devzone.nordicsemi.com/f/nordic-q-a/17906/reading-battery-voltage-using-nrf51822Hi, I am working on reading battery voltage of nRF51822 Microcontroller. I have used the openbecon(internet) code for ADC configuration and reading. I am getting 28 or 27 as ADC output. is there any mistake in the code..??
