Product List
In the example above, a red circle and the text “FTDI” are drawn at the center of the LCD screen. It should be noted that LCD panels almost always start with the 0,0 coordinate in the upper left corner. X increases left-to-right. Y increases top-to-bottom. The placement and sizes of the objects are handled in 1/16th pixel increments as part of the built-in anti-aliasing features of the FT800. In each of the lines, the notation “wr32(address, value)” simply indicates that 4 bytes are being written to the FT800 over the interface. The FT800 Programmers Guide indicates the actual values associated with the various display list functions. A total of 2000 display list commands can be included in a single display list. The Display List always starts by clearing the screen and is always terminated by Display and swapping the list. Primitives start with BEGIN and end with END, or the next BEGIN for a new primitive type.
