433和315无线模块的软件编解码遥控程序1：单片机软件解码PT22402：选用PIC16F877A作为软件解码芯片3：单片机时钟频率选用外部4MHZ晶振4：选用外部中断脚作为编码信号脚输入脚5：可解PT2240芯片（8脚的学习型编码芯片 编码地址位：2的20次方 重复几率100万分之一）6：功能有：遥控器学习（DEMO上的S9作为学习按纽） 清除记忆（长按DEMO上的S9即可清除遥控器地址的记忆）7：学习遥控器数量可以设定（可根据EEPROM的大小 随便设定）8：输出功能（有三路是 单击遥控器双稳，可以通过PORTC上的LED可以看到结果还有一路是 双击遥控器双稳）9：可选用315MHZ433MHZ的超再生超外差接收模块/*/* 遥控器接收程序 */*/#include #include #define remote_geshu 10/*/union BIT_16 int TIMER1_REG;
