This is the best documentation for getting started: https://micropython-usermod.readthedocs.io/en/latest/usermods_05.html That whole site is made by the creator of ulab and details in a good detail how to setup the plumbing in C for creating the module and types and functions within it. Just start s...

You may want to wait because the ESP32S3 is sampling and supposed to go to mass production soon. It will support 8MB usable PSRAM and larger amounts of flash 16 MB or some will have 32MB. I think you can have larger values for both psram and flash but those are just what is included on die. Checkout...

I found out that you can have the board hold on a hard fault. This will show you the stack trace where the problem occurred:

I have a micropython firmware that integrates the tensorflow micro c++ api. It works for ESP32 and I'm trying to increase the number of boards it supports starting with stm32 with a Nucleo H743ZI2 board (1MB RAM, 2MB Flash). I'm encountering an issue when I try to run the hello world example where i...

Getting them from the python side is very clean and easy. Here are some details on how they are setup on the C side. They are setup in the local scope of the I2S class here: https://github.com/micropython/micropython/blob/42d1a1635cc35fd3a9ae28b19685184fc3c23f1e/ports/esp32/machine_i2s.c#L666 The MP...

I have it working on esp32 with an INMP441 mic. I just put some notes together on my wiring and then the I2S configuration block I am using: https://github.com/mocleiri/tensorflow-micropython-examples/tree/main/examples/micro-speech/esp32 I also have a script that you can run to sample audio to a 2 ...

The rp2 pull request #6960 has been merged. My pull request #6956 works and is greatly simplified now that its using the rp2 port contributions. If anyone has custom esp32 firmwares can you checkout the branch from my pull request and see if it works for you? Its successfully built the usercexample'...

Thanks @v923. I will circle back later and follow those useful links to allow doing the mfcc transform in micropython using ulab.

I had some trouble getting the c++ example to build but I just finished pushing my code that supports user modules on esp32 using the rp2 port approach. https://github.com/micropython/micropython/pull/6956 Caveat : I changed how the qstr.i.last file is generated and while it works I have no idea if ...

I was able to get the approach used by the rp2 to work on esp32 so will adapt my pull request to share the same approach. The base changes will go in on their pull request: https://github.com/micropython/micropython/pull/6960 Then I'll adjust mine(https://github.com/micropython/micropython/pull/6956...
