ADC_Init#

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

Initialize ADC.

Parameters
[in]adc

A pointer to the ADC peripheral register block.

[in]init

A pointer to the ADC initialization structure.

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.

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
