Could some one assist and clarify how to use the callback function HAL_DAC_ConvCpltCallbackCh1(DAC_HandleTypeDef* hdac) with STM32U575CGU6. I try to integrate mp3 player with STM32U575CGU6. I checked flags and the status of DAC. All works but call-back functions HAL_DAC_ConvCpltCallbackCh1(DAC_HandleTypeDef* hdac) and HAL_DAC_ConvHalfCpltCallbackCh1(DAC_HandleTypeDef* hdac) do not work. Please assist. Thanks! Please see part of the code below. ////////////////////////////////////////////////////// ////this is a place of handling for the callback function////////
void HAL_DAC_ConvCpltCallbackCh1(DAC_HandleTypeDef* hdac)
{
if (AudioPlayerState == PLAYER_PLAYING )
{
MP3_callback();

}

Please give me advice on how to work with call back function correctly.
