128x64 GLCD
A liquid crystal display (LCD) is a flat panel display, that uses the light modulating properties of liquid crystals (LCs).
Interfacing 128x64 GLCD with Spartan-3 Primer FPGA
The Spartan-3 Primer board has 128x64 GLCD, indicated as in Figure. 14 pins are needed to create 8-bit interface; 8 data bits (DB0-DB7), two chip select line (CS1) and (CS2), address bit (R/S), read/write bit (R/W) and control signal (E) and Reset (RST). The GLCD controller is a standard S6B0108 or equivalent, which is a very well-known interface for Graphical based LCDs. Figure below illustrate the GLCD part of the design and which pins are used for the interface. The GLCD is powered from the 5V power supply enabled by switch SW1.
