本文是自已写的电子密码锁的详细开发过程，用的是Modelsim进行仿真实现，打开文档lzp-This article is written in their own electronic locks detailed development process, using a ModelSim simulation achieved, open the document lzp

OpenRISC 1200 cpu with integrated patches to support ORPSOC and FuseSOC builders

这是用VHDL实现的8位加法器，对新手有点帮助。-This is achieved using VHDL adder 8, a little help to novices.

电机控制中PWM波产生的程序，VHDL语言实现-Motor Control PWM wave generated by the procedure, VHDL language

这是一个nios工程，控制TFT液晶屏的程序。FPGA平台用Verilog HDL语言编写的，MCU软核程序有C语言编写。通过这一个完成的工程，你就会明白SOPC的一些实现方法。(This is a nios engineering, control TFT LCD screen program. The FPGA platform Verilog HDL language preparation with the nuclear program has a soft, MCU written in C language. Through this a complete project, you will understand some of the SOPC methods of realization. )

掌握SDRAM数据读写、刷新、初始化以及FPGA串口收发时序，熟练FIFO IP核的生成和调用。(Master SDRAM data read and write, refresh, initialization and the timing of sending and receiving of the serial port of the FPGA, skilled in the generation and invocation of the FIFO IP core.)

本程序实现任意占空比产生，已经在easyfpga030综合过-This procedure generated to achieve an arbitrary duty cycle

7对于进入密码锁的按键，假设复位后七个灯显示" 0"，而使用sw5、sw6 2，则只要按下并松开sw5后七个灯就显示" 5"，而只要按下并松开sw6，七个灯就正确显示值" 6
