Interfacing LCD module and FPGA
Text LCD modules are cheap and easy to interface using a microcontroller or FPGA.To control an LCD module, you need 11 IO pins to drive an 8-bits data bus and 3 control signals. The 3 control signals are: E: enable, or “LCD-select”. Active high,R/W: read/write. 0 to write, 1 to read,RS: register select, 0 for command bytes, 1 for data bytes. Most of the LCD modules are based on the HD44780 chip or compatible.
