【正文】 ses the C language to carry on the software design, carries on various functions software module in the hardware foundation the the software design uses the modular structure, makes the programming the logical relations to be simpler easy to understand. Because this design demonstrated with the liquid crystal for the carrier, therefore has the good manmachine interaction contact surface and the friendly operation, may demonstrate the time, the date, the week, the temperature and have the noisy bell function. Keywords: AT89C51 monolithic integrated circuit。 DS18B20 安徽工程大學(xué)畢業(yè)設(shè)計(jì)（ 論文） III 目錄 目 錄 ..........................................................................................................................................
