Detailed Description

Macros to configure clock source of different peripherals.

Macro Definition Documentation

__HAL_RCC_ADC_CONFIG

#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

<strong>ADCCLKSOURCE</strong>

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

__HAL_RCC_GET_ADC_SOURCE

#define __HAL_RCC_GET_ADC_SOURCE

(

)

((uint32_t)(READ_BIT(RCC->CFGR, RCC_CFGR_ADCPRE)))

Macro to get the ADC clock (ADCxCLK, x=1 to 3 depending on devices).

Return values

The

clock source 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
