Hello,

I am trying to understand if I could create a PXT module for STM32 microcontroller. The application of STM32 board based on freertos.

I would like to know if there are any examples of using CODAL with freertos to create PXT module ? And if it is possible ?

For example how it was done by Lego for their operating system:

> **[microsoft/pxt-ev3](https://github.com/microsoft/pxt-ev3)**
>
> Microsoft MakeCode editor for the LEGO MINDSTORMS EV3 Brick - microsoft/pxt-ev3

Please give me some advice!

Thanks!
