The proposal uses a single-chip puter AT89 C51 as the Master Control chip. The hardware system makes upof the clock chip DS1302, temperature sensor DS18B20 , buttons, LCD display modules. Hardware system has f ive independent buttons and a LCD display, which can display a wealth of information. In accordance with the needs of users, time can be calibrated at any time, chosen the time and soon. To sum up this calendar has some advantages, for example easy to read, showing intuitive, feature-rich, circuit simplicity, low cost. In line with the electronic instrumentation of the development trend, the calendar has the broad market prospects. 电子信息工程系毕业论文- II- 目录摘要.................................................................................................................................
