单片机实现DES的程序包-DES realize single-chip package

用89S52编的的蜂鸣器发声，有点简单，但最为一个发声的实力来说足够了-89S52 series with the buzzer sound, a bit simple, but most of the strength of a voice enough for the

系统由AT89C51、LED 数码管、按键、发光二极管等部分构成，能实现时间的调整、定 时时间的设定，输出等功能。系统的功能选择由SB0、SB1、SB2、SB3、SB4 完成。其中SB0 -System consists of AT89C51, LED digital tube, keys, light-emitting diodes and other parts, to achieve the adjustment of the time, will be When the time set, the output functions. Function of the system choose from SB0, SB1, SB2, SB3, SB4 completed. One SB0

遥控小汽车的设计 可以有限速区和加速区 对他完全实现自动控制-remote control cars designed to be limited to the speed zones and accelerating the full realization of his control

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

GPS模块与单片机89s51之间的数据通信，单片机存储定位信息，并在LED上显示出来-Single-chip GPS module and the data communication between 89s51, single-chip storage location information, and displayed in the LED

这是新华龙（www.xhl.xom.xn）开发的，基于单片机，现在可以在它的网站上免费下载，不过当初他可是花了500大元买的。 --It is developed by www.xhl.xom.xn and based on SCM.

计算CRC16/CRC8/CRC32的程序，可获得CRC-CCITT/CRC-16/CRC-8/CRC-32的计算结果。 提供Delphi源代码和MCS51单片机的汇编源代码，分别采用两至三种不同算法实现。有比较详细的调用和使用说明。 更新历史: 2003/05/04 新增CRC-8算法的实现。 2004/02/02 修改CRC-8算法，新增CRC-32算法，增加比较详细的调用和使用说明。-CRC16/CRC8/CRC32 calculation procedures available CRC-CCITT/CRC-16/CRC-8/CRC-32 the calculated results. Delphi provide source code and compile the MCS51 source code, adopted two to three different algorithm. A more detailed calls and use. Update History : 2003/05/02 new CRC-8 algorithm implementation. 2004/02/02 changes CRC-8 algorithm, the new CRC-32 algorithm, adding more detailed calls and use.

I2C的源代码,经本人测试通过,完全没有任何错误-I2C source code, as I tested, there is no any error
