How to read the battery ? dose it required any separate circuit or just ADC pin is enough?
Actually for the battery voltage which is connected to VDD you just have to tell the function that you want ADC of VDD.
nrf_saadc_channel_config_t config = NRF_DRV_SAADC_DEFAULT_CHANNEL_CONFIG_SE(NRF_SAADC_INPUT_VDD);
Rest just checkout the example in peripheral/saadc
Ty so much
