引言

網(wǎng)上有很多一線總線的產(chǎn)品,我覺(jué)得這項(xiàng)技術(shù)的前景不錯(cuò),自己用C也寫(xiě)了一個(gè)測(cè)溫的程序.

并通過(guò)PROTEUS進(jìn)行了仿真.

搞了很多天,終于搞出來(lái)了,心里高興的很,拿出來(lái)曬一下!

一. 原理介紹

說(shuō)明:

1.單片機(jī)采用PIC16F877A,主要是由于液晶顯示需要自己寫(xiě)字庫(kù),所以需要大容量的EEPROM,而他有8K字節(jié).

2.液晶使用的是KS0108控制器系列,他的指令比較簡(jiǎn)單,性價(jià)比較高.

3.溫度傳感器采用的是1-WIRE總線技術(shù)的DS18B20,測(cè)的溫度分辨率高.

附另外兩張效果圖

二. 器件介紹

DS18B20的相關(guān)資料

讀寫(xiě)時(shí)序復(fù)位時(shí)序操作ROM的指令內(nèi)部框圖讀出數(shù)據(jù)說(shuō)明

四. 總結(jié)

曾經(jīng)因?yàn)橐痪€總線檢測(cè)存在脈沖的子程序的延時(shí)不對(duì),低電平持續(xù)不到480uS,所以程序一直沒(méi)有進(jìn)展,且找不到問(wèn)題原因,耽擱了好多天,昨天偶然中發(fā)現(xiàn)了這個(gè)原因,一下就成功了,看來(lái)還是不夠仔細(xì).

通過(guò)這個(gè)例子,我掌握了KS0108系列液晶的編程及DS18B20溫度傳感器的使用.但還是有很多不夠完善的地方,如1.程序按鍵不是很靈敏,2.還可以多加些功能,3.有些子程序?qū)懙煤軣?但不管怎么樣,總算寫(xiě)出來(lái)了,有興趣的朋友可以看一下.
