STM32H743 ADC calibration timeout

Question asked by handzic.dirk on May 17, 2018

My ADC clock is 25 MHz and

HAL_ADCEx_Calibration_Start(&hadc1, ADC_CALIB_OFFSET_LINEARITY, ADC_SINGLE_ENDED) will return an error due to ADC_CALIBRATION_TIMEOUT being exceed I changed the value from 64000 to 640000 and now it works fine. It seems to take about 65683 cycles at my system.

 

Regards

Dirk
