超低功耗電子溫度計(jì) 超低功耗電子溫度計(jì)摘要:本次設(shè)計(jì)的超低功耗電子溫度計(jì),采用低功耗的MSP430F2012單片機(jī)作為核心控制部件。根據(jù)題目的具體要求,采用熱敏電阻NTC100和MSP430內(nèi)部自帶的AD轉(zhuǎn)換實(shí)現(xiàn)溫度的采集功能,利用HT1621顯示芯片和16位數(shù)碼液晶玻璃片實(shí)現(xiàn)了數(shù)據(jù)顯示功能,并采用3*1鍵盤實(shí)現(xiàn)了功能之間的轉(zhuǎn)換及調(diào)節(jié)。整個(gè)系統(tǒng)都是在超低功耗的要求下進(jìn)行元件及運(yùn)行方式選擇的,只需要一片SONY的銀鋅電池(3V)即刻實(shí)現(xiàn)長(zhǎng)時(shí)間運(yùn)作,很好的實(shí)現(xiàn)了超低功耗、高精度、可喚醒等功能。關(guān)鍵詞: MSP430單片機(jī);超低功耗;熱敏元件;溫度計(jì)Abstract:The Ultralow power electronic thermometer uses the lowpower MSP430F2012 MCU as the core control ponents. According to the pecific equirements of this title, we uses the thermistor NTC100 and the MSP430 internal builtin AD conversion to plete the collection of temperature, besides, we uses the HT1621 and 16 digital LCD glass to achieve a data display .By using the 3*1 keyboard ,we achieves the conversion between the functions and regulation. The whole system is in the UltraLowPower requirements for ponents and operation mode of choice ,which need only one silverzinc batterie(SONY 3V) to achieve long operation, and achieved ultralow power, high precision and awakenabled functions very well.Key words: MSP430,ULP, Thermosensor, Thermometer一 、系統(tǒng)設(shè)計(jì):1 題目要求2 任務(wù):設(shè)計(jì)一個(gè)電子溫度計(jì),能夠通過(guò)溫度傳感器測(cè)量并顯示被測(cè)量點(diǎn)的溫度。原理方框圖如下:MSP430單片機(jī)溫度傳感器顯示驅(qū)動(dòng)顯示按鍵設(shè)計(jì)要求: 1 基本部分: (1) 檢測(cè)溫度范圍10~30℃,分辨率1℃; (2) 正確顯示溫度 (3) 整機(jī)靜態(tài)功耗小于5微安(關(guān)閉LCD顯示,時(shí)鐘正常運(yùn)行) (4) 按鍵喚醒顯示 2 發(fā)揮部分: (1) 溫度控制功能(能夠演示出控制功能的存
