Description

Help write a MicroPython library of ES8311 sensor.
I hope it is a library that uses Python completely, and can play sound and read sound by microphone, because the speaker and microphone chip of ESP32P4 is ES8311. thank you

Code Size

As big as it can be, don't have too much flash space.

Implementation

I hope the MicroPython maintainers or community will implement this feature, I intend to implement this feature and would submit a Pull Request if desirable

Code of Conduct

Yes, I agree

ES8311 is an audio codec (ADC+DAC) and uses I2S for audio data. You should be able to use machine.I2S to communicate with it. There are many examples how to work with I2S in MicroPython at https://github.com/miketeachman/micropython-i2s-examples
You can also find some I2S example code in https://github.com/emlearn/emlearn-micropython/tree/master/examples/soundlevel_iir

Note that the ES8311 codec may need some setup before it provides audio on the I2S bus of the format you want. This is done using I2C commands.

I just got stuck in the I2C command and asked for a library.

[jonnor]

Aha. I have not seen any I2C driver for this chip for MicroPython. I recommend looking at the code from a driver in another language, and porting the initialization sequence over. Here is one example, https://github.com/espressif/esp-bsp/tree/4dabefca0599b2249d356cb6a08268dd5e56bbaf/components/es8311
