| Abstract: | In order to enhance the practicality of the bus-stop system and enhance the capacity of bus services, the design of the current time and temperature display. The use of serial time clock chip DS1302 for acquisition time, single-bus digital temperature sensor DS18B20 for temperature collection, the information dealt with by the MCU and transported to the LCD display. The hardware and software design of the interface contact with MCU is described in detail,the accuracy and reliability of the system running was verified through the Proteus simulation platform. The hardware design was simple and reliable, software programming was easy and can be transplanted to other home appliances or industrial and agricultural production real- time control system. |
