Hi All,
Attachment is SAI in DMA mode source code generate from CubeMX, but the code doesn't works. DMA interrupt in this code can't be trigger so no data receive from SAI.
- I can run demo code SAI_AudioPlay on STM32L476 Nucleo board, it works.
- I can receive data in SAI blocking mode ( HAL_SAI_Receive() ), but get nothing in DMA mode ( HAL_SAI_Receive_DMA() )
SAI is i2s Master mode and audio signal come form Audio Precision PISA-2722. Where needs to be fixed?
Thanks!
