说明：  基于DMX512协议的接收程序，使用STC12C2052单片机，16M晶振，在没有接收到DMX512信号时，3路LED红绿蓝自行渐变，有15种效果，当接上DMX512信号时自行响应。
(DMX512 protocol receiver based program that uses STC12C2052 microcontroller, 16M crystal, DMX512 signal is not received, the three-way LED RGB own gradient, there are 15 kinds of effects, when connected to the DMX512 signal itself when responding.)
