三種單片機(jī)模擬串口方法介紹模擬串口就是利用51的兩個(gè)輸入輸出引腳如P1.0和P1.1,置1或0分別代表高低電平,也就是串口通信中所說(shuō)的位,如起始位用低電平,則將其置0,停止位為高電平,則將其置1,各種數(shù)據(jù)位和校驗(yàn)位則根據(jù)情
熱電偶也叫溫差電偶,是最早出現(xiàn)的一種熱電探測(cè)器件。其工作原理是溫差電效應(yīng)。例如,由兩種不同的導(dǎo)體材料構(gòu)成的接點(diǎn),在接點(diǎn)處可產(chǎn)生電動(dòng)勢(shì)。這個(gè)電動(dòng)勢(shì)的大小和方向與該接點(diǎn)處兩種不同的導(dǎo)體材料的性質(zhì)和兩
