style="text-indent:25px">無線通訊模塊中單片機(jī)對接收模塊的干擾：單片機(jī)模擬2262時一般都很正常，然而單片機(jī)模擬2272解碼時通常會發(fā)現(xiàn)遙控距離縮短很多，這是因?yàn)閱纹瑱C(jī)的時鐘頻率的倍頻都會對接收模塊產(chǎn)生干擾，51系列的單片機(jī)電磁干擾比較大，2051稍微小一些，PIC系列的比較小，我們需要采用一些抗干擾措施來減小干擾。比如單片機(jī)和遙控接收電路分別用兩個5伏電源供電，將接收板單獨(dú)用一個78L05供電，單片機(jī)的時鐘區(qū)遠(yuǎn)離接收模塊，降低單片機(jī)的工作頻率，中間加入屏蔽等。接收模塊和51系列單片機(jī)接口時可以做一個隔離電路，能較好地遏制單片機(jī)對接收模塊的電磁干擾。接收模塊工作時一般輸出的是高電平脈沖，不是直流電平，所以不能用萬用表測試，調(diào)試時可用一個發(fā)光二極管串接一個3K的電阻來監(jiān)測模塊的輸出狀態(tài)。影響代理
