DMX 512协议是Digital Multiplex的缩写，是灯光行业数字化设备的通用信号控制协议，同时也是是一种国际协议。 　　USITT DMX512/1990是调光和灯光控制台数据传输标准，是娱乐灯光领域常用的控制协议。以前0-10V模拟控制用的比较多，现在DMX512是娱乐灯光行业最主要的控制协议。USITT DMX512/1990是由美国剧场技术协会USITT提出的。最原始的版本出版于1986年，在1990年做了修改。 (DMX 512 protocol is short for Digital Multiplex is light industry, general-purpose digital signal device control protocol, but also is an international agreement. USITT DMX512/1990 is dimming and lighting control data transmission standard, is commonly used in the field of entertainment lighting control protocol. 0-10V analog control previously used more, now is the entertainment lighting industry, the main DMX512 control protocol. USITT DMX512/1990 by the American Association of Theater Technology USITT s. The original version published in 1986, was revised in 1990.)

一个新的通信协议，一线通协议模版软件，希望对大家开发有用(A new communication protocol, Link Agreement template software, everyone would like to develop useful)

绝对原创代码，目前正在产品上应用。基于NXP的LPC2220的串口升级程序，在PC端用VC++ 6.0编写，对于ARM7特别是IAP升级具有很好的参考价值。(Absolute original code, and is currently being applied on products. Based on NXP' s LPC2220 serial upgrade, in the PC side using VC++ 6.0 to prepare for the ARM7 particular IAP upgrades have good reference value.)

实验了界面组态和串口通信，完成了界面显示，通过串口变化功能(Experimental interface configuration and serial communication, completed through the serial interface display change function)

同步机制的解决方法之一(one of the solutions)

modbus协议栈，供大家参考！ 供大家参考！(modbus connection protocol stack, for your reference! For your reference!)

本程序实现了用位图作为全平的主窗口,是全平显示的又一种实现方法,(This program realizes using bitmap as the main window of full flat, which is another realization method of full flat display.)
