硬件電路連接實現(xiàn)單片機與nRF2401芯片的接口連接。發(fā)送端與接收端硬件連接幾乎一樣,具有通用性,可以實現(xiàn)半雙工通信。單片機使用的是MCS51系列的AT89C52,成本低,控制簡單,容易擴展。硬件電路設計主要包括DC/DC電源供電電路設計、nRF2401芯片與+5V單片機的接口設計以及nRF2401芯片的外圍電路設計。電路圖如圖2所示。

單片機與nRF2401芯片的接口電路

  圖2 單片機與nRF2401芯片的接口電路

  由于nRF2401的供電電壓范圍為1.9~3.6V,而AT89C52單片機的供電電壓是5V,為了使芯片正常工作,需要進行電平轉換和分壓處理。單電源供電時,采用MAX884芯片進行5V-3.3V電平轉換。

  +5V單片機I/O口與nRF2401芯片引腳的接口需要進行分壓處理,單片機向nRF2401發(fā)送控制信號和配置信號時采用電阻分壓,nRF2401向單片機傳送數(shù)據(jù)或者發(fā)送數(shù)據(jù)狀態(tài)信號時采用74HC04反向器兩級反向,這樣就可以實現(xiàn)兩個芯片在電壓允許范圍內的雙向通信。也可以使用專用的雙向電平轉換芯片。單片機通過PWM_UP,CE,CS三端設置nRF2401的工作模式,表1列出nRF2401的四種工作模式。配置模式時單片機通過CLK1和DATA端向nRF2401發(fā)送配置字,發(fā)送數(shù)據(jù)時通過CLK1和DATA端向nRF2401發(fā)送地址和數(shù)據(jù),接收數(shù)據(jù)時通過CLK1和DATA端從nRF2401讀取數(shù)據(jù),DR1是nRF2401通知單片機已經接收到數(shù)據(jù)并且可以讀取的狀態(tài)信號。CLK2、DOUT和DR2端為通道二保留使用,nRF2401可以同時接收兩路信號。

nRF2401的四種工作模式

  nRF2401芯片以及其外圍元件電路組成了發(fā)送接收模塊。這部分重要的是PCB板的設計,使用兩層的PCB板,盡量多打一些通孔,使頂層和底層的地能夠充分接觸,空余部分大面積連續(xù)接地。電源濾波電容盡量靠近VDD引腳,注意調整電阻、電容和電感的位置。這樣能夠獲得好的射頻性能。

  3.單片機對nRF2401芯片軟件控制

  使用nRF2401芯片進行無線數(shù)據(jù)通信時不需要進行曼徹斯特編碼,編程和應用非常方便。單片機對nRF2401芯片的控制包括在配置模式下對nRF2401的初始化配置、發(fā)送數(shù)據(jù)和接收存儲數(shù)據(jù)。配置字一共18byte,設定的具體參數(shù)見表2。發(fā)送端和接收端的配置必須匹配,只有配置字的位不同。數(shù)據(jù)包格式包括前綴、地址、有效數(shù)據(jù)和CRC。發(fā)送數(shù)據(jù)包時單片機只向nRF2401傳送地址和數(shù)據(jù),前綴和CRC會在nRF2401芯片內部自動加進去。接收數(shù)據(jù)包時,接收端檢測到本機地址的數(shù)據(jù)包,檢驗正確后會自動移去前綴、地址和CRC,將有效數(shù)據(jù)傳送給單片機。
