how can I send data through I2S to cs43l22 chip in stm32f4 discovery to play a .wav audio file stored in sdcard ?

[Sherif Armanyous]

I am using :

• STM32CubeMX
• Keil mdk V5

what is configured and working correctly :

• SDCard Fatfs using spi protocol
• I2c to control cs43l22.
• PD4 RESET of audio coded cs43l22.

what is needed :

• the right configuration of I2s and DMA and how to send PCM data from SDCard to cs43l22
