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.)

自己做的CRC16校验例子，输入16进制数据，数据之间用空格，得到校验字节(The CRC16 checksum own example, enter the hexadecimal data, with a space between the data check byte)

说明：  U盘读写模块，实现电脑与U盘自动连接，发送，传输数据(U-reader module, computerization and U disk automatically, sending, transmission of data)

电脑之间蓝牙的通信，相当于一个蓝牙工具吧。(Bluetooth communication between computers, the equivalent of a Bluetooth tool bar.)

说明：  说明：此为球形开关测试程序的上位机软件。 能够记录由下位机上传的每支球形开关 的通断情况，自动记录上传的时间， 并且会将历次的结果保存在PC机的硬盘 中，带有具体的日期，方便查询。(Note : This spherical switch to the testing procedures PC software. To record the next crew uploaded each spherical switch-off, automatically records upload time, and will keep all the previous results of the PC's hard disk, with the specific date, and easily accessible.)

并口通讯，通过并口控制打字机刻在自行车上，防止自行车丢失(Parallel port communication, and by the parallel port control typewriter engraved on the bike, to prevent the a bike to lost)

计算机网络实验做得串口，非原创，只是为了下载方便。(Computer network experiments do serial port, not original, just for download convenience.)
