Question about i2s_read parameters
Posted: Mon Jan 31, 2022 9:47 pm
Hello!
I am building an audio recording system with an ESP32 and external adc (PCM1865)
To start the data reading, I use:
i2s_read(I2S_NUM, user_given_buffer[cnt], user_given_buffer_size, &i2s_bytes_read, 100);
My question is, what is "&i2s_bytes_read" ? And how to use it?
Thank you
