加入分布式电源后，配电网可靠性的研究，从知网上下的文章哦，挺有用的(After the addition of distributed power supply with the reliability of the grid research, top to bottom of article HowNet Oh, quite useless)

ATSHA204 主要特性： 1，SHA-256 Hash算法 2，有保证的唯一的72-bit序列号； DS28CN01　６４－ｂｉｔ 不仅有软件加密，内部还有高质量硬件加密。 3，16个槽口的4kbits EEPROM： 4Kbits / 8 = 512Bytes 每个槽口32bytes 4，I2C接口, 单线接口 5, 和Atmel AT88SA102S，AT88SA10HS 6, i2c 地址默认为0xc8； 还可以configuration zone改变地址。(CryptoAuthentication Device Family Atmel offers the industry s widest selection of hardware authentication and encryption devices. The portfolio is currently comprised of three parts with several others under development. Our CryptoAuthentication devices provide confirmation that hardware and software products are real, which is what authentication is all about. The devices are extremely cost-effective and come in exceptionally small packages.)

基于At89c52和数码管实现的秒表，具有正向计时、倒计时和清零功能，三个按键分别对应k1（开始计时、暂停、继续）、k2（倒计时、暂停、继续）、k3（停止、归零）。文件包括源码、工程文件、仿真原理图和工程文件。(Based At89c52 and implement digital stopwatch, has a positive time, countdown and clear function, three buttons corresponding to k1 (start time, pause, resume), k2 (countdown, pause, resume), k3 (stop, zero ). File contains the source code and schematics.)
