HAL DAC io operation functions migration ¶

This section provides information about the HAL DAC io operation functions migration.

HAL DAC conversion in polling mode ¶

HAL1	HAL2
HAL_DAC_Start HAL_DAC_Stop	HAL_DAC_StartChannel HAL_DAC_StopChannel

Related use cases: Use case: DAC using software trigger mode

HAL DAC in DMA mode ¶

HAL1	HAL2
HAL_DAC_Start_DMA HAL_DAC_Stop_DMA	HAL_DAC_StartChannel_DMA HAL_DAC_StopChannel_DMA

Related use cases: Use case: Single channel DAC transfer using DMA

HAL DAC set value ¶

In HAL2, the HAL_DAC_SetValue is split into two separate functions.

HAL1	HAL2
HAL_DAC_SetValue(DAC_HandleTypeDef *hdac, uint32_t Channel, uint32_t Alignment, uint32_t Data);	/* During the Initialization and configuration sequence, user provides the alignment to be used by the driver / HAL_DAC_SetChannelAlignment(hal_dac_handle_t hdac, hal_dac_channel_t channel, hal_dac_data_alignment_t alignment); /* each time, user wants to set the DAC data, call the appropriate function without providing again the alignment / HAL_DAC_SetChannelData(hal_dac_handle_t hdac, hal_dac_channel_t channel, uint32_t data); /* If needed, user can change the alignment after the init and configuration sequence using the same function HAL_DAC_SetChannelAlignment */

HAL1

HAL2

                HAL_DAC_SetValue(DAC_HandleTypeDef *hdac,
                 uint32_t Channel, uint32_t Alignment,
                 uint32_t Data);

               

                /* During the Initialization and configuration sequence, user provides the alignment to be used by the driver  */
HAL_DAC_SetChannelAlignment(hal_dac_handle_t *hdac,
                            hal_dac_channel_t channel,
                            hal_dac_data_alignment_t alignment);
/* each time, user wants to set the DAC data, call the appropriate function without providing again the alignment */
HAL_DAC_SetChannelData(hal_dac_handle_t *hdac,
                                hal_dac_channel_t channel,
                                uint32_t data);
/* If needed, user can change the alignment after the init and configuration sequence using the same function HAL_DAC_SetChannelAlignment */

               

Related use cases: Use case: DAC using timer trigger or external trigger
