The R64 Frame Buffer allows you to set up to 16x16 R64 Colour LED Displays in one go. The Frame Buffer can be manualy set in its GUI by clicking first on the colour selectors to set which colour will be drawn when the drawing area is left or right clicked. You need to use a MCI Location to set the bottom right R64 Colour LED Display. You can dynamically set the Frame Buffer by supplying the line number (Y coord, 0 to 15) to the Right R64 Input and the colour value to the Left R64 Input (Colour is set when the Left R64 Input recieves a number, so the line number needs to be sent first).
