Hello all,

I recently updated my micropython VGA library for the pico 2.

https://github.com/HughMaingauche/PICO2-VGA-Micropython

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).
This library uses 3 PIO statemachines and 2 DMA channels
A full framebuffer and a font, once loaded in memory, will leave approx 270k of available memory to do stuff and use a VGA monitor directly connected to the PICO

Other improvements are:

Use of the DMA included library available in the standard micropython instead of direct registry modification used in my previous code
Changed the font system to use xglcd fonts (from rdagger library)
Added a plotting library to make real time plotting more easy

I tried to document the code as much as I could. I have no doubt that this can be optimized quite a lot.
If any of you is interested in using or improving it, i'll be happy to provide further explanations.

Hugh
