◆ ADC_Init()

void ADC_Init	(	ADC_TypeDef *	`adc,`
		const ADC_Init_TypeDef *	`init`
	)

Initialize ADC.

Initializes common parts for both single conversion and scan sequence. In addition, single and/or scan control configuration must be done. See ADC_InitSingle() and ADC_InitScan() respectively. For ADC architectures with the ADCn->SCANINPUTSEL register, use ADC_ScanSingleEndedInputAdd() to configure single-ended scan inputs or ADC_ScanDifferentialInputAdd() to configure differential scan inputs. ADC_ScanInputClear() is also provided for applications that need to update the input configuration.

Note: This function will stop any ongoing conversion.

Parameters

[in]	`adc`	A pointer to the ADC peripheral register block.
[in]	`init`	A pointer to the ADC initialization structure.

◆ ADC_Reset()

void ADC_Reset ( ADC_TypeDef * adc )

Reset ADC to a state that it was in after a hardware reset.

Note: The ROUTE register is NOT reset by this function to allow a centralized setup of this feature.

Parameters

[in] adc A pointer to ADC peripheral register block.

◆ ADC_InitScan()

void ADC_InitScan	(	ADC_TypeDef *	`adc,`
		const ADC_InitScan_TypeDef *	`init`

See ADC_Start() for starting a scan sequence.

When selecting an external reference, the gain and offset calibration must be set explicitly (CAL register). For other references, the calibration is updated with values defined during manufacturing. For ADC architectures with the ADCn->SCANINPUTSEL register, use ADC_ScanSingleEndedInputAdd() to configure single-ended scan inputs or ADC_ScanDifferentialInputAdd() to configure differential scan inputs. ADC_ScanInputClear() is also provided for applications that need to update the input configuration.

Note: This function will stop any ongoing scan sequence.
