溫度采集單元的實現(xiàn)
溫度采集單元主要溫度信號的實時采樣并響應(yīng)主機的命令[31。本系統(tǒng)溫度傳感器使用DS1 8B20，DS1 8B28B20是美國半導(dǎo)體DALLAS公司推出的單總線溫度傳感器。該器件具有體積小、結(jié)構(gòu)簡單、實用電壓寬、可組網(wǎng)、成本低廉、便于總線擴展和維護等諸多優(yōu)點，而且內(nèi)有控制電路，收發(fā)電路和存儲電路等。DS18B20 具有較寬的電壓適用范圍(3～5．5V)，并能夠通過編程實現(xiàn)溫度信號的9～12位的數(shù)字轉(zhuǎn)換，分辨率zui高可以達到0．0625℃。其測量溫度范圍為-55～+125℃，其中，在-10～+85℃范圍內(nèi)，精度能夠達到±0．5℃。器件采用CMOS技術(shù)，耗電量很小，能夠直接讀出被測溫度并且可根據(jù)實際要求通過簡單的編程實現(xiàn)一位分辨率的數(shù)字值讀數(shù)方式。使用微處理器作為控制機時，可以使用一位普通端口，就可驅(qū)動傳感器芯片，本系統(tǒng)采用GPB7引腳來驅(qū)動DS18B20。由于DS1 8B20是通過一條數(shù)據(jù)線傳輸數(shù)據(jù)， 這樣整個系統(tǒng)要嚴(yán)格按該器件單總線協(xié)議規(guī)定的時序進行工作， 所以DS 1 8B20有嚴(yán)格的通信協(xié)議來保證各個數(shù)據(jù)傳輸?shù)恼_性和完整性。根據(jù)DS 1 8B20的通訊協(xié)議，主機控制DS 1 8B20完成溫度轉(zhuǎn)換時，首先在每一次讀寫之前對DS1 8B20進行復(fù)位，復(fù)位成功后發(fā)送一條ROM指令，然后發(fā)送RAM 指令，這樣才能對DS18B20進行預(yù)定的操作。R O M 操作命令主要是對傳感器地址的操作。RAM 指令主要完成溫度的測量，主要有讀寄存器，寫寄存器，溫度轉(zhuǎn)換等操作。
2．4 鍵盤及LCD顯示單元
系統(tǒng)采用SPI接口的鍵盤控制芯片ZLG 72 8與$3C2410A的SPI接口連接，ZLG7289掃描的行線R[2：0】和列線C[7：0】構(gòu)成矩陣鍵盤，同時在芯片內(nèi)部可自動完成掃描、譯碼、去抖動處理等任務(wù)。
S3C2410A內(nèi)部已經(jīng)集成了LCD 控制器，因此可以很方便地控制各種類型的LCD屏，例如：STN和TFT屏。系統(tǒng)采用Samsung 3．5 反射型TFT液晶LTS350Q1，320 X 240像素，256k色，White LED背光，自帶四線式觸摸屏，可以直接和S3C2410A的觸摸屏驅(qū)動電路連接，觸摸位置直接用CPU內(nèi)置的ADC電路采樣可得。
鍵盤和LCD連接示意圖如圖2所示。
