基于５１单片机的乘法运算程序

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

在cygnal020开发板下的lcd（菜单）部分显示程序设计，利用数据表的结构，将菜单设计方法简化，便于菜单项修改。但是占用存储空间较大。-In cygnal020 under development board lcd (menu) of the display program design, use of the data table structure design methods to simplify the menu, easy to modify menu items. However, larger storage space occupancy.
