LED驱动器MAX7219的如此特别。MAX7219是微处理器和共阴极结构
MAX7219驱动LED特好使.MAX7219是微处理器和共阴极七段― ― 八位LED显示、图条/柱图显示或64点阵显示接口的小型串行输入/输出芯片。片内包括BCD译码器、多路扫描控制器、.字和位驱动器和8X 8静态RAM。外部只需要一个电阻设置所有LED 显示器字段电流。MAX7219和微处理器只需三根导线连接,每位显示数字有一个地址由微处理器写入。允许使用者选择每位是BCD 译码或不译码。使用者还可选择停机模式、数字亮度控制、从1~8选择扫描位数和对所有LED显示器的测试模式。-LED Driver MAX7219 so special. MAX7219 is a microprocessor and a total cathode seventh-- 8 LED display, map article/column or 64 shows a small dot-matrix display interface serial input/output chips. Chip including the BCD decoder, multiplex scan controller. Word and bit drive and 8X 8 static RAM. External resistor only need one set all LED displays current field. MAX7219 and the microprocessor only three wires to connect, each show has an address by the digital microprocessor write. Is to permit users to choose each BCD decoding or not decoding. Users can also choose to shutdown mode, the digital brightness control, 1 ~ 8 to choose from scanning the median and LED displays for all the test mode.

通用运行监控平台的设计与实现.将报警与探测分离开来,让“探测”掌握在维护
人员自己手里,使维护人员可以自由使用系统本身的一些探测工具,同时也可自主开应用级探测命令,再通过该监控软件,把所有的探测结果以统一的形式来报警,从而做到灵活通用性,便于运行上实现集中监控。-Common monitoring platform to run the design and implementation. Will be separate from the alarm and detection, so that " detect" rests in the hands of their own maintenance personnel, so that maintenance personnel are free to use the system itself, some of the detection tools, but also to open their own application-level probe command, and then through the monitoring software, all the detection results in a uniform manner to the police, to be flexible and versatile, easy to run on a centralized control.
