本源码是用verilog编写控制LCD——使用Quartusii，开发平台使用的是DE2开发板，可实现1602上任意字符显示

嵌入式系统典型应用源代码，包括键盘检测，LCD显示，计时器等-Typical applications source code for embedded systems, including the keyboard detection, LCD display, timer, etc.

第二章 设计思路 2.1 设计总体框图 有分析可知，本次课程设计可以分成五个木块来实现相应的功能，分别是输入模块，计算模块，扫描模块，输出模块以及显示模块。((Calculator design based on FPGA DE2 development board. language use Verilog. Matrix keyboard input, LCD1602 display. Program includes key scanning module and LCD modul
