What started as a project to learn C, I have now been using in all my hobby projects. HAGL is a hardware agnostic graphics library for embedded projects. It supports basic geometric primitives, bitmaps, blitting, fixed width fonts and an optional framebuffer. Yet another graphics library? Most embedded hobbyist projects do not seem to care about code reuse. Instead there is a graphics library for everydifferentdisplaydriver for every different architecture. They all implement the same functio...
