We wish to measure battery voltage with ADC.
We are using RAK3172 module + RUI3
Here we try to set internal reference voltage of ADC to the 1.8V or 2.4V by using functions
When we read ADC mode back with function “udrv_adc_get_mode()” it gives UDRV_ADC_MODE_3_3 (ie. Mode value - 1)
It seems that internal voltage is not getting set to the desired voltage level.
Please guide us to resolve this issue.
