能实现功能有：显示年、月、日、星期、时、分、秒、阴历月日、温度，共21位数码管。其中星期和阴历月日能根据公历自动计算改变，到2050年之前有效。温度可以测量从-10到40℃之间的温度。还可以设定两个定时、12/24小时显示、自动亮暗切换的时间等。
电路只用了两片IC，一片M48，另外一片是74LS145，4-10译码器，来扩充端口。具体电路在下面，是PROTEUS画的，给个图片做参考-To achieve functions: Display year, month, day, week, hour, minute, second, lunar month, the temperature, a total of 21 digital tube. One week and the lunar month on the Gregorian calendar automatically calculated based on changes effective prior to 2050. Can measure temperatures from-10 to 40 ℃ temperature between. Also can set two time, 12/24 hour display, automatic light switch dark time. Circuit used for only 2 IC, an M48, the other is a 74LS145 ,4-10 decoder to expand the port. Specific circuit in the following is the PROTEUS painting, a reference to a picture
