This Visualisation Library signaling protocol provides the interface between an LCD controller peripheral (for example the PL110) and a visualization component. This permits the LCD controller to render the framebuffer contents into a region of the visualization GUI.
LISA visualization components can provide any number of LCD ports. The implementations of these behaviors can delegate the calls to appropriate methods on the VisRenderRegion class.
The behaviors are:
lock()
: VisRasterLayout *
unlock()
update(int x, int y,
unsigned int w, unsigned int h)
setPreferredLayout(unsigned
int width, unsigned int height, unsigned int depth)
