In this project, I used 12864-12 LCD .For the controller part, I chose the Spartan3 serial FPGA, the XA3S1500, which developed by the Xilinx Cooperation. The program of the controller is written by VHDL language, and the main body of the program used state machine as the primary control method. In this LCD controller, there are two major parts, which are the character display module and the picture display module. The character display module put the Character Calling Ram and the display control module together to enable the user to call the embedded character library easily to display the information he/she needed. For the picture display module, the module, through specific algorithm, solved the problems that the x address of the picture display buffer kept stepping forward after every 16 times and the display screen are divided into 2 section by the buffer. And this module, by reading a picture ram, displayed picture which was put earlier. In this project, I finally realized the following function. The first one is to display any 16*16 pixels Chinese character and 16*8 pixels English character on any position of the display screen. The second one is the display information will instantaneously update as the input data changes. The last function is that any given picture data can be displayed properly on the LCD screen. The research of this project will contribute to the developing process of those
