| Abstract: | The system, in this worke, with AT89C51 microcontroller as the master chip temperature measurement system uses first - line temperature sensor DS18B20 for temperature measurement combines with 128 × 64 dot matrix LCD module OCM12864 as a display and visually displays the measured temperature. This paper introduces the hardware structure, software programming method and the basic features of a digital temperature sensor DS18B20. It also describes DD RAM address corresponding with the crystal lattice relations and the rules of Chinese characters and Chinese menu display on the LCD module. |
