It is! Can be found in the website folder, and it's called gendoc.nim: https://github.com/PMunch/ratel/tree/master/website

which is this great project btw: https://github.com/PMunch/ratel

what happened to that cool landing page you had?

The author of ratel also did a talk on microcontroller programming with Nim for FOSDEM. It doesn't bring up MicroPython, but it does bring up TinyGo and some other alternatives mentioned in this thread.

Hi guys, So I'm trying to program a Mikrobus rp2040 with PyCharm and I can run some basic code with it. What I need help with is installing the ulab for the numpy-like array operations that I need for my project. I tried all the instructions there, I'm not very experienced with manual installation of these libraries.

https://freertos.org/ for example is a popular OS, that has realtime capabilities and fits in 9KB of RAM. https://micropython.org is basically a µC OS too, understands Python 3 Syntax and works with 16KB of RAM already. It might appear more convoluted at first, but you can get it to be real-time too by following the same principles as in any RTOS (react to stuff by means of ISR, allocate memory only initially and then work in place to prevent fragmentation, switch of GC and so on). Image processing is just linear algebra for the most part, and there's even an Numpy equivalent available to crunch that. There are also two decorators in Micropython that allow for compilation for most of the Python syntax, which would work for stuff that can not be written down in a vectorized way.

Has anyone of you managed to install a micropython version with ulab for your esp32? I tried the procedure on the ulab github but without any succes. When I try it stops at sth like: "no submodule. stop."

or if you want simpler, faster to implement and faster to compute, try micropython-ulab

Or maybe youre doing data science?
