stm32f446re SAI with DMA transfer

cobblestone · ‎2026-02-20

I'm trying to make audio equipment using stm32f446re board and pcm5102 module. When I used the audio equipment, when I sent music using i2s communication, the output came out well, but when I finished DMA setting after selecting i2s protocol in sai, the output didn't come out smoothly. (DMA checked operation using callback)
Also, I checked pcm5102 can be operated no external sck.
What's the problem?
