INTERPHASE CORP 4020-000 INAV4000 6U PICMG 2.16 GIGABIT ETHERNET CPCI NETWORK數(shù)據(jù)為5 2―直置為“0”，并使+，清零，則不論9位數(shù)據(jù)（+9 8）為何值，下位機均可產(chǎn)生串行接收中斷，這樣9位就可作為差錯檢測的奇偶校驗位了。如上位機與某下位機通信時，發(fā)送地址碼，待握手成功后再發(fā)送數(shù)據(jù)命令，此時該下位機的FLAG被置為“”，相當于該機的“口袋”已打開，上位機不斷從該下位機中取數(shù)據(jù)，取完無誤后發(fā)出命令使該下位機中的FLAG復原為“0”，實現(xiàn)“關(guān)口袋”。
下位機向上位機發(fā)送數(shù)據(jù)時，發(fā)送要傳送數(shù)據(jù)的長度，然后才開始發(fā)送有效數(shù)據(jù)。
約定00H為取數(shù)命令，0FFH為復位命令，通信采用偶校驗，波特率設(shè)為2400b/s.上面給出PC機主函數(shù)的流程圖，如所示。PC機通信程序采用VC++6.0語言編寫。下位單片機的通信模塊，包括主程序和中斷服務(wù)程序，其程序流程圖分別如和所示。何實現(xiàn)上位機與相應發(fā)送地址相符的下位機之間通信呢，可采用軟件方法。具體方法如下：在下位機程序中設(shè)立個標志變量FLAG，初始化時FLAG置為“0”，當上位機發(fā)送數(shù)據(jù)時，各下位機均會產(chǎn)生接收中斷，中斷服務(wù)程序判斷本機FLAG的值。若FLAG為“0”，則把接收的數(shù)據(jù)與本機地址比較，如果，則置FLAG為6“，并發(fā)回本機地址碼作為應答，否則馬上跳出中斷服務(wù)程序；如果FLAG是”“，說明上位機發(fā)送來的是控制命令，則轉(zhuǎn)相應命令處理程序，后才跳出中斷服務(wù)程序，返回主程序。上位機與該下位機通信完畢后，再令該下位機的FLAG為”0“。如果握手失敗，則上位機發(fā)送復位命令給下位機，然后重新開始握手，三次都不成功則轉(zhuǎn)出錯處理。邁普公司作為中國專業(yè)數(shù)據(jù)通信廠商的民族品牌，20年專注于黨政、運營商、金融、工等行業(yè)的網(wǎng)絡(luò)通信領(lǐng)域。作為國內(nèi)民族企業(yè)自主可控的領(lǐng)鋒，不遺余力研發(fā)自主可控的網(wǎng)絡(luò)和安全產(chǎn)品，采用龍芯2H芯片開發(fā)了NSS4320系列自主可控安全交換機于204年2月上市發(fā)布，在各個領(lǐng)域得到速的應用。
