DDL_ADC12_DMA_GetRegAddr()

__STATIC_INLINE uint32_t DDL_ADC12_DMA_GetRegAddr	(	ADC12_TypeDef *	ADCx,
		uint32_t	Register )

Function to help to configure DMA transfer from ADC: retrieve the ADC register address from ADC instance and a list of ADC registers intended to be used (most commonly) with DMA transfer.

Note

These ADC registers are data registers: when ADC conversion data is available in ADC data registers, ADC generates a DMA transfer request.

This macro is intended to be used with DDL DMA driver, refer to function "DDL_DMA_ConfigAddresses()". Example: DDL_DMA_ConfigAddresses(DMA1, DDL_DMA_CHANNEL_1, DDL_ADC12_DMA_GetRegAddr(ADC2, DDL_ADC12_DMA_REG_REGULAR_DATA), (uint32_t)&< array or variable >, DDL_DMA_DIRECTION_PERIPH_TO_MEMORY);

For devices with several ADC: in multimode, some devices use a different data register outside of ADC instance scope (common data register). This macro manages this register difference, only ADC instance has to be set as parameter.

Parameters

ADCx	ADC instance
Register	This parameter can be one of the following values: DDL_ADC12_DMA_REG_REGULAR_DATA DDL_ADC12_DMA_REG_REGULAR_DATA_MULTI (1) (1) Available on devices with several ADC instances.

Return values

ADC	register address
