HAL SAI transfer I2S on STM32F469I-Disco
Hi, how do i send data to the CS43L22 codec on the board? In the audio example, it sends 16bit uint values with the eval_audio_play, but on the HAL_SAI_transmit functions i can only send 8bit values. I cannot find a solution, i configured the DAC and...
STM32F4xx/F7xx: USB to I2C interfacing for audio play/record
Hallo, I cannot find any guideline on how to use the I2S and USB peripheral in order to interface PCs and Mac to I2C D/A and A/D converters. Talking about USB asynchronous with speeds up to 384LB/s. These boards are nowadays designed with specialise...
I2S slave lost syncronization
Posted on September 03, 2017 at 08:50 Hello, I use I2S interface on STM32F446 to read audio stream in slave mode. The master transmits MCLK, BCLK, DATA and WS signals. At the beginning everything works fine. At random point in time the strea...
