本例采用89C52, 晶振为11.0592MHZ，关于如何编制音乐代码, 其实十分简单,各位可以看以下代码.频率常数即音乐术语中的音调,而节拍常数即音乐术语中的多少拍 所以拿出谱子, 试探编吧!-Example use of the 89C52, crystal for 11.0592MHZ, on how to prepare music code, is actually very simple, you can see the following code. Frequency that is constant in terms of tonal music, and the constant beat of music terminology that is how much of the shoot so come up with music score , test made it!

使用AT98S51控制1602液晶显示程序，AT89S51使用12M晶振。

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
