This design of a CPLD-based controls HS162 to achieve character LCD display. The use of state machine design, programming by instruction of HS162 LCD module s read/write operations, as well as screen and cursor operations. Verilog HDL module written language design process. I used Quartus II software to complete the design and simulation. Primarily through software programming of CPLD, and provide power, clock, download the program, and reset other peripheral circuits necessary to achieve control of the character LCD to display the default character.
