void ADC_SetInjectedOffset	(	ADC_TypeDef *	ADCx,
		uint8_t	ADC_InjectedChannel,
		uint16_t	Offset
	)

Set the injected channels conversion value offset.

Parameters

ADCx	where x can be 1, 2 or 3 to select the ADC peripheral.
ADC_InjectedChannel	the ADC injected channel to set its offset. This parameter can be one of the following values: ADC_InjectedChannel_1: Injected Channel1 selected ADC_InjectedChannel_2: Injected Channel2 selected ADC_InjectedChannel_3: Injected Channel3 selected ADC_InjectedChannel_4: Injected Channel4 selected
Offset	the offset value for the selected ADC injected channel This parameter must be a 12bit value.

Return values

None

void ADC_SoftwareStartConv

(

ADC_TypeDef *

ADCx

)

Enables the selected ADC software start conversion of the regular channels.

Parameters

ADCx	where x can be 1, 2 or 3 to select the ADC peripheral.

Return values

None

Examples:

dma.c.

Here is the caller graph for this function:

void ADC_SoftwareStartInjectedConv

(

ADC_TypeDef *

ADCx

)

Enables the selected ADC software start conversion of the injected channels.

Parameters

ADCx	where x can be 1, 2 or 3 to select the ADC peripheral.

Return values

None

void ADC_StructInit

(

ADC_InitTypeDef *

ADC_InitStruct

)

Fills each ADC_InitStruct member with its default value.

Note

This function is used to initialize the global features of the ADC ( Resolution and Data Alignment), however, the rest of the configuration parameters are specific to the regular channels group (scan mode activation, continuous mode activation, External trigger source and edge, number of conversion in the regular channels group sequencer).

Parameters

ADC_InitStruct

pointer to an ADC_InitTypeDef structure which will be initialized.

Return values

None

Here is the caller graph for this function:

void ADC_TempSensorVrefintCmd

(

FunctionalState

NewState

)

Enables or disables the temperature sensor and Vrefint channels.

Parameters

NewState

new state of the temperature sensor and Vrefint channels. This parameter can be: ENABLE or DISABLE.

Return values

None

Definition at line 589 of file stm32f4xx_adc.c.

void ADC_VBATCmd

(

FunctionalState

NewState

)

Enables or disables the VBAT (Voltage Battery) channel.

Note

the Battery voltage measured is equal to VBAT/2 on STM32F40xx and STM32F41xx devices and equal to VBAT/4 on STM32F42xx and STM32F43xx devices

Parameters
