Hi all,
I used the STM32F051's ADC function. If I Enable the Auto-off mode (AUTOFF), in the power-off state, the calibration value that produced from HAL_ADCEx_Calibration_Start() will be deleted ?

Hi

,Based on RM0091:
As ADC power is not removed by ADEN bit nor the auto-off mode, once calibration was done, auto-off mode does not require re-calibration.
But during the time (auto-off enabled), if the STM32F051 MCU enters the standby mode, supply voltage will be removed from VDD/VDDA connected to ADC. So calibration will be required.
