@w84death I know you're the one writing the OS and I'm the one watching, but have you heard of the PROGMEM keyword in Arduino C++? It allows you to store data that would usually be in RAM in flash. (I see you tagged Clang though)
@golemwire Yes, I found that recently. I'm using PROGMEM for ALL the strings. As each string even the one in parameters for a function took a piece of ram.
When I need to print a string, I first copy the data from PROGMEM variable to the small buffer and use that buffer for print parameter. I'll do that to every string in the app.
Unfortunately those buffers NEEDS to be in ram. And the screen one is way too big - that's why I found a sweet spot of 112x88 pixels to work with.
