La nueva familia de PIC24FJxxxDAxxx , trae un nuevo periferico llamado Graphics Controller Module. Caracteristicas extraidas del datasheet:
The Graphics Controller (GFX) module is specifically
designed to directly interface with the display glasses,
with a built-in analog drive, to individually control pixels
in the screen. The module also provides an accelerated
rendering of vertical and horizontal lines, rectangles,
copying of rectangular area between different locations
on the screen, drawing texts and decompressing
packed data. The use of the accelerated rendering is
performed using command registers. Once initiated,
the hardware will perform the rendering, and the
software can either poll the status, or use the interrupts
to continue rendering of the succeeding shapes.
