Display Controller
The display glass must be constantly refreshed by feeding the horizontal and vertical pixel data repeatedly from the frame buffer. This can be achieved in two ways.
-
Dedicated Display controller – External/Internal to the MCU
-
MCUs with Direct Memory Access (DMA) and PMP/EBI interface – This approach is called Low Cost Controllerless Graphics (LCCG)
