This is the source code for I2C(Inter Integreted Circuit) which is used in serial communication

基于quartus 的一些程序 都是verilog 还是比较有用的 -Based on some of the procedures Quartus Verilog are still quite useful

1602是目前最常用的显示器件，本例是通过verilog 代码实现1602的显示(1602 display)

说明：  制作16位流水灯，实现LED模块对于拨杆0和1的识别(Making 16-bit pipeline lamp to realize the recognition of dial rod 0 and 1 by LED module)

基于Verilog 的电子日历与电子时钟程序，可以进行调日期、星期、时间的分钟与小时，通过几种模式来显示日历与时间。-Verilog-based electronic calendar and e-clock procedures, can be adjusted date, week, time of minutes and hours, through several models to display a calendar and time.

实现4种常见波形正弦、三角、锯齿、方波（A、B）的频率、幅度可控输出（方波 A的占空比也是可控的），可以存储任意波形特征数据并能重现该波形，还可完成 各种波形的线形叠加输出。 -Realize four kinds of common sine wave, triangle, sawtooth, square wave (A, B) the frequency, magnitude controllable output (square wave A, is also a controllable duty cycle), can store arbitrary waveform feature data and can reproduce the waveform, but also completed a variety of linear superposition of the output waveform.

说明：  本实验为UART回环实例，实验程序分为顶层unrt_top、发送模块uart_tx、接收模块 uart_rx，以及时钟产生模块clk＿div。uart＿rx将收到的包解析出8位的数据，再传送给 uart_tx发出，形成回环。参考时钟频率为100MHz，波特率设定为9600bps。(This experiment is an example of UART loop. The experimental program is divided into top-level unrt_top, sending module uart_tx, receiving module uart_rx, and clock generation module clk_div. Uart_rx parses the received packet into 8 bits of data and sends it to uart_tx to send out, forming a loop. The reference clock frequency is 100 MHz and the baud rate is set to 9600 bps. stay)
