A Liquid Crystal Displayed Method of I/O Bus Driving Based on CPLD
一种基于CPLD的I／O总线驱动液晶显示的方法

The paper discusses a new kind of driving the LCD via I/O bus using CPLD and realizing the precise I/O control timing sequence by establishing the corresponding Verilog-HDL model. The results of application show that this solution can not only solve the matching of low-speed device with high-speed bus but also provide the display interface during the motherboard debugging process, and also prove that the whole system is reliable and stable.
