Does anybody have an software examples that allow to set up and send data for STM32L496 Serial Audio Interface (I2S)?

What problems exactly?

What is PACK?

I use the PACK 2.3.0. for the micro STM32L496 on the Nucleo-L496ZG board.

After SAI1_A initialisation using HAL_SAI_Init(&hsai_BlockA1), I tried to send data using

HAL_SAI_Transmit(&hsai_BlockA1, (u8*)&test_sai, countof(test_sai), HAL_MAX_DELAY).

Everything is supposed to be OK: PLLSAI1, clock selection, settings for SAI1, frame and slot settings, etc.

There is nothing on SAI1_A pins.

Thanks,

Alex

Hello,

I can set up SAI's pll, frame, slot parameters successfully. Unfortunately, there is some problem with sending data. When I use the function HAL_SAI_Transmit, I can see that FIFO is fully loaded with data, SAI is enabled using __HAL_SAI_ENABLE(hsai), but there is no data on the SD pin. I can see FS and SCK signals.

Does anybody have any ideas what could cause the problem?

Thanks,

Alex
