#define __HAL_RCC_ADC_CONFIG

(

__ADCCLKSOURCE__

)

MODIFY_REG(RCC->CFGR, RCC_CFGR_ADCPRE, (uint32_t)(__ADCCLKSOURCE__))

Macro to configure the ADCx clock (x=1 to 3 depending on devices).

Parameters:

__ADCCLKSOURCE__

specifies the ADC clock source. This parameter can be one of the following values: RCC_ADCPCLK2_DIV2 PCLK2 clock divided by 2 selected as ADC clock RCC_ADCPCLK2_DIV4 PCLK2 clock divided by 4 selected as ADC clock RCC_ADCPCLK2_DIV6 PCLK2 clock divided by 6 selected as ADC clock RCC_ADCPCLK2_DIV8 PCLK2 clock divided by 8 selected as ADC clock

Macro to get the USB clock (USBCLK).

Return values:

The	clock source can be one of the following values: RCC_USBCLKSOURCE_PLL PLL clock divided by 1 selected as USB clock RCC_USBCLKSOURCE_PLL_DIV1_5 PLL clock divided by 1.5 selected as USB clock
