Are there instructions someplace on how to create an image that can be burned into an M5 Core2?

I'd like to make an image with Micropython, LVGL, etc. so I have more capability than the base image, but I also want to be able to preserve support for Audio and other Core2 specific functionality.

Thanks

Yes, I want to be able to build a firmware file with MicroPython & LGVL.

How do you cross compile for the ESP32? How do you then make the firmware image?

Where would I find the details needed to build an image to run on the Core2?

Thanks

Thanks. Any kind of sound would be great.

My machine module doesn't have the I2S used in this example.

I'm developing on the Core2 with Micropython LVGL.

Is there someway to use the 3 capacitive buttons?

@purpledread

Never mind. As simple Python code.

Thanks!

@staberas

This code was very helpful. Thanks!

I tried adding temperature as well:

tmp = i2c.readfrom_mem(MPU6886_ADDRESS, MPU6886_TEMP_OUT_H, 2)
temp = (tmp[0]<<8|tmp[1])
temp = (float(temp) / 326.8) + 25.0;

I'm getting temps of 40.5C (105F). Am I doing something wrong or is this temperature the CPU temp?

Thanks,

Sorry for the newbe questions. You've been a big help.

When you say you load files to ram from the boot.py file, how do you access that ram from the main.py file?

@macsbug

I really appreciate the response, but I'm running with an image that just has lvgl and micropython and not the M5 classes.

Looking for how to play a sound with the standard esp32 hardware support on the device.

Should have mentioned I'm running on a M5Core2.
