FPGA将从CY7C68013读到的数写入SRAM-FPGA will read a few CY7C68013 write SRAM

基于Altera公司系列FPGA(Cyclone EP1C3T144C8)、Verilog HDL、MAX7219数码管显示芯片、4X4矩阵键盘、TDA2822功放芯片及扬声器等实现了《电子线路设计• 测试• 实验》课程中多功能数字钟实验所要求的所有功能和其它一些扩展功能。包括：基本功能——以数字形式显示时、分、秒的时间，小时计数器为同步24进制，可手动校时、校分；扩展功能——仿广播电台正点报时，任意时刻闹钟（选做），自动报整点时数（选做）；其它扩展功能——显示年月日（能处理大月小月，可手动任意设置年月日），秒表（包括开始、暂停和清零）。(based Altera FPGA series (Cyclone EP1C3T144C8) , Verilog HDL, MAX7219 Digital Display chips, 4x4 matrix keyboard, TDA2822 chip power amplifier and loudspeakers of the "Electronic Circuit Design)

说明：  简单的一个Verilog小程序，适合刚接触的人群(A simple Verilog small program, suitable for people just contact)

说明：  使用FPGA测量频率大小，并且在数码管上进行显示(Frequency measurement using FPGA and display on digital tube)
