Embedded systems #300

Open davidvfx07 opened 4 months ago

davidvfx07 commented 4 months ago

I've been interested in creating a language that can be interpreted on embedded systems (esp32) with platformio, arduino and esp-idf for use in a larger project. I came across pocketlang and it fits into this project really nicely. However, while I've managed to get it to compile successfully with platformio, there are Guru Meditation errors when registering libs (backtrace attached bellow).

So is this indeed the case, and if so, is there a way to workaround or fix it? If not, where can one be pointed to when considering embedding pocketlang into a project on a microcontroller?

PS. I am interfacing with pocketlang through the language Nim and its flexible FFI features with a Nim module named NimPk. I don't think it should be an issue, but I'll point it out just in case.

There is an issue on the nimpk module repo in case the info there can help, khchen/nimpk#1.

UPDATE. Moved to RP2040 for convenience. I think I'm going to stay here and manually implement the libraries I want from within Nim. The std_lib isn't very important to the project anyway. I am still doing a lot of testing around memory, and will report back with any meaningful discoveries for those interested...
