Could someone assist and clarify how to configure GPDMA for DAC for use the callback function HAL_DAC_ConvCpltCallbackCh1(DAC_HandleTypeDef* hdac) with STM32U575CGU6.
I caught:
/* Data Transfer Error Interrupt management */
if ((__HAL_DMA_GET_FLAG(hdma, DMA_FLAG_DTE) != 0U))
/* Update the DMA channel error code */
hdma->ErrorCode |= HAL_DMA_ERROR_DTE;
My goal is to catch the callback functions:
HAL_DAC_ConvCpltCallbackCh1(DAC_HandleTypeDef* hdac) and HAL_DAC_ConvHalfCpltCallbackCh1(DAC_HandleTypeDef* hdac)
and integrate mp3 player with STM32U575CGU6.
Before STM32U575CGU6 I worked with STM32F413 and my the code worked.
Please assist.
Thanks!
Please see some parts of the code for explaining.
