实现用单片机控制直流电机调速功能，可用，有hex文件(Achieve MCU control DC motor speed control function is available, a hex file)

It was a ATmega128 Sleep mode and awake mode programed by avr studio4

AES128/196/256 加解密源码，可实现ECB模式加密，HEX输出。密码及明文没有补齐功能，需手动补齐。无需特殊库文件，适合单片机使用。已测试，可正常使用。(AES128/196/256 encryption source code, can achieve ECB mode encryption, HEX output. The password and the plaintext without the need to manually fill up function. No special library files, suitable for single use. Has been tested, can be used normally.)

求质立方体的广义星轵发,用于数字系统设计自动化(seeking quality cube of generalized end of axle outside of hub-made for digital system design automation)

电力系统电度表通讯协议，主要针对DL645协议标准(Power system meter communication protocol, mainly for DL645 protocol standards)

此程序可实现长度为8位，周期为255的m序列，此序列可当做伪随机信号发生器，模拟信道噪声。(This procedure can achieve the length of 8 bits, the m sequence of 255 cycles, the sequence can be used as a pseudorandom signal generator, analog channel noise.)

这是一个带有时钟,闹钟的桌面宠物程式. 还有记事功能!!COOL(This is a clock, alarm clock, desktop pet programs. There Notepad function!! COOL)

AVR128显示部分，用12864作为显示的程序代码，已经调试通过(AVR128 display section, with 12864 as display the program code, have debugging through)

此程序可实现长度为8位，周期为255的m序列，此序列可当做伪随机信号发生器，模拟信道噪声。(This procedure can achieve the length of 8 bits, the m sequence of 255 cycles, the sequence can be used as a pseudorandom signal generator, analog channel noise.)
