定时器中断实验代码， 定时器3进行0.1秒定时，每0.5秒改变一次P2,P3口的值以产生走马灯效果。-timer interruption experimental code, three timers for 0.1 seconds regularly, every 0.5 seconds to change a P2, P3 to the values I have merry-go-round effect.

该模拟器是在Keil7.0中使用。 只要把Ex02Dll.dll复制到 X:KeilC51BIN目录下。 打开测试程序，编译运行即可看到如图led.jpg中所显示的效果。-The simulator is used in Keil7.0. As long as Ex02Dll.dll copied to the X : Keil C51 BIN directory. Open test procedure, compile operation can be seen in figure led.jpg reflected by the results.

AVR单片机的优化RC6 加密算法（速度快，其优化思想绝对值得学习） 在有128bytes RAM 的AVR单片机上执行 rc6 16/10/8(16 bit/10 rounds/8 bytes keys) * 对多数代码进行了 C 语言优化，对数据相关循环移位，模乘等用ASM优化 * 在4MHz无乘法器的AVR上得到平均 1172 Bytes/s的加解密速度。 * 编译器: AVR-G-AVR optimization RC6 encryption algorithm (faster, optimizing their thinking definitely worth learning) 128bytes of RAM in the AVR on the implementation of production 16/10/8 (16 bit/10 rounds/8 bytes keys)* for the majority of code optimization of the C language the data related to cycle shift, mode used by other optimization* ASM 4MHz without the multiplier be average AVR 1172 Bytes/s speed encryption and decryption.* Compiler : AVR-G

DS1302，DS18B20，中断三个子函数，可直接调用。-DS1302, DS18B20, disruption of the three Functions can be called directly.
