SAADC_TASK_CALIBRATEOFFSET

[OKA_T.T]

Environment: nRF5_SDK_15.3.0_59ac345 s112_nrf52810_5.1.0_softdevice.hex

Supply voltage: 3.3V

 When executing nrf_drv_saadc_init() after executing nrf_saadc_task_trigger(NRF_SAADC_TASK_CALIBRATEOFFSET), the callback function is not set and NRF_DRV_SAADC_EVT _CALIBRATEDONE cannot be obtained.

①：How can I get the ADC offset correction completion?

②：How can I get the status of ADC offset correction not yet executed and ADC offset correction in progress?

③：What are the conditions under which the offset correction value is cleared?

Hi 

You should run nrf_drv_saadc_init() before you attempt to calibrate the ADC. 

Can you confirm whether or not you do this?

For tips on using the SAADC feel free to have a look at the following examples:
