RS编码是一种纠错码，本程序实现RS（255，223）用FPGA 实现RS编码，程序在Quartus II中调试通过。(RS coding is an error-correcting codes, the procedures for the realization of RS (255,223) with FPGA realization of RS codes, in the Quartus II program through the debugger.)

LED灯、跑马灯的显示源程序，包括对代码的说明(Display source code LED lights, marquees, including the code specification)

RS232的UART编程，包括波特率发生器模块，串口接受模块，串口发送模块(RS232 programming the UART, including the baud rate generator module, serial module to receive, send serial module)

高斯最小频移键控（Gaussian Filtered Minimum Shift Keying），这是GSM系统采用的调制方式。数字调制解调技术是数字蜂窝移动通信系统空中接口的重要组成部分。GMSK调制是在MSK（最小频移键控）调制器之前插入高斯低通预调制滤波器这样一种调制方式。GMSK提高了数字移动通信的频谱利用率和通信质量。(Gauss Filtered Minimum Shift Keying is a modulation method used in GSM system. Digital modem technology is an important part of air interface of digital cellular mobile communication system. GMSK modulation is a method of inserting a Gaussian low-pass pre-modulation filter before the MSK (minimum frequency shift keying) modulator. GMSK improves the spectrum utilization and communication quality of digital mobile communication.)

说明：  数字示波器实验，利用AD、DA和VGA三个外设来实现简易示波器，DA外设发送正弦波给AD外设，AD外设解析成数字信号将数据送给VGA外设进行显示。在VGA上可以看到DA外设发送的波形、波形频率和波形峰峰值。(In the experiment of digital oscilloscope, AD, DA and VGA are used to realize simple oscilloscope. DA peripheral transmits sine wave to AD peripheral. AD peripheral resolves into digital signal and sends data to VGA peripheral for display. The waveform, waveform frequency and peak value of DA peripheral can be seen on VGA.)

用键盘控制FPGA，再由FPGA控制VGA显示器是好东西-Use the keyboard to control FPGA, and then by the FPGA to control VGA display is a good thing
