One-off, low accuracy measurement of battery voltage using ADChttps://devzone.nordicsemi.com/f/nordic-q-a/1746/one-off-low-accuracy-measurement-of-battery-voltage-using-adcI&#39;ve seen various threads here with sample code attached that show how to set up a timer to measure a battery voltage periodically. They also seem to use an external crystal for greater accuracy. What if I need neither of them?

I&#39;d been setting up the ADC stuff <em>before</em> the softdevice was enabled in my code. With it after, this works as expected.

I do hit the breakpoint at ADC_IRQHandler. Did you check if sd_nvic_SetPriority and sd_nvic_EnableIRQ are returning any error codes others than NRF_SUCCESS (0x00)?</p> <p>Also if you have the SoftDevice disabled, please use the CMSIS APIs NVIC_SetPriority and NVIC_EnableIRQ instead of the SoftDevice APis.</p> <p>Cheers, Balaji</p><div style="clear:both;"></div>
