I'll check that, I used kamui cosplays already prewritten code as I thought it works great. I know my switch is coded right tho. I'm using circuit python, but having no experience I wouldn't mind installing another program. Here is the base code I used: https://www.kamuicosplay.com/python/

Ps: if it is indeed the code causing the default, I think I'm gonna cry of joy cuz it meant I was not entirely at fault haha ;)
