Hello All,

This is an upgrade of my previous VGA micropython display library, using the pico2 allows to use a VGA screen with a 800x600 resolution and 3 bits per pixel (8 colors). A full framebuffer and a font, once loaded in memory, will leave approx 280k of available memory to do stuff and use a VGA monitor directly connected to the PICO

I tried to document the code as much as I could. I have no doubt that this can be optimized quite a lot.
