基于FPGA的电子密码锁控制电路的设计，包涵源代码和密码锁的整体组装设计原理图-FPGA-based electronic code lock control circuit design, includes source code and password lock schematic design of the overall assembly

本程序是一个密码锁程序。包括四位密码的读取、识别、设置等。-This program is a combination lock program. Including four password to read, identification, setting, etc.

主要是实现电子密码锁的功能，有记忆和错误提示报警功能，较完善地实现密码锁的功能。-Electronic password lock function, memory and error alarm function, the password lock function better.
