LL_DAC_DMA_GetRegAddr() function

Function to help to configure DMA transfer to DAC: retrieve the DAC register address from DAC instance and a list of DAC registers intended to be used (most commonly) with DMA transfer. (1) On this STM32 series, parameter not available on all devices. Refer to device datasheet for channels availability.

Summary

Declaration

from stm32f4xx_ll_dac.h:938

__STATIC_INLINE uint32_t LL_DAC_DMA_GetRegAddr(const DAC_TypeDef *DACx, uint32_t DAC_Channel, uint32_t Register);

Arguments

Argument

Description

DACx

DAC instance

DAC_Channel

This parameter can be one of the following values: @arg LL_DAC_CHANNEL_1 @arg LL_DAC_CHANNEL_2 (1)

This parameter can be one of the following values: @arg LL_DAC_DMA_REG_DATA_12BITS_RIGHT_ALIGNED @arg LL_DAC_DMA_REG_DATA_12BITS_LEFT_ALIGNED @arg LL_DAC_DMA_REG_DATA_8BITS_RIGHT_ALIGNED

Return value

DAC register address

Notes

These DAC registers are data holding registers: when DAC conversion is requested, DAC generates a DMA transfer request to have data available in DAC data holding registers. This macro is intended to be used with LL DMA driver, refer to function "LL_DMA_ConfigAddresses()". Example: LL_DMA_ConfigAddresses(DMA1, LL_DMA_CHANNEL_1, (uint32_t)&, LL_DAC_DMA_GetRegAddr(DAC1, LL_DAC_CHANNEL_1, LL_DAC_DMA_REG_DATA_12BITS_RIGHT_ALIGNED), LL_DMA_DIRECTION_MEMORY_TO_PERIPH); DHR12L1 DACC1DHR LL_DAC_DMA_GetRegAddr\n DHR8R1 DACC1DHR LL_DAC_DMA_GetRegAddr\n DHR12R2 DACC2DHR LL_DAC_DMA_GetRegAddr\n DHR12L2 DACC2DHR LL_DAC_DMA_GetRegAddr\n DHR8R2 DACC2DHR LL_DAC_DMA_GetRegAddr
