struct ADC_InitTypeDef

#include <bf0_hal_adc.h>

Structure definition of ADC initialization and regular group.

备注

The setting of these parameters with function HAL_ADC_Init() is conditioned to ADC state. ADC state can be either:

For all parameters: ADC disabled (this is the only possible ADC state to modify parameter ‘ClockPrescaler’)
For all parameters except ‘ClockPrescaler’ and ‘resolution’: ADC enabled without conversion on going on regular group. If ADC is not in the appropriate state to modify some parameters, these parameters setting is bypassed without error reporting (as it can be the expected behaviour in case of intended action to update another parameter (which fulfills the ADC state condition) on the fly).
