Data format 24 bit, MSB first, sample rate 48kHz. Test message - 0x0300bb55.
Size of I2S-master buffer = size of I2S-slave buffer = 128.

I transmit debugging information in terminal via USB-TTL module. A part of buffer on a picture.

Anybody knows why data is multiplied by 2 and how do I solve this problem? Maybe I have problem in inicialization of ESP8266 I2S ?

I'd like to transmit data from STM32 to ESP8266 continuously through I2S interface, but non-OS SDK does not support cyclical mode. Maybe OS SDK has instruments for my problem.
