I used it as reference. I2S registers described in ESP31_RTOS don't match up with registers described in esp-idf sdk. For example, using ESP31_RTOS, I2S_CONFIG register setups modes of operation and clock, but esp-idf defines two new registers to setup clocks(sample rate) and another for delays. It'...

Hi, I building audio application with ESP32 too. I was able to enable I2S clock, rout I2S signals to GPIO trough GPIO_matrix, setup periferal clock and sample rate. I still need to switch serial data output/input, don't know how :( I manage to do it based on this file "esp-idf/components/esp32/inclu...
