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.

正弦交流电路计算机
计算机辅助正弦交流电路分析的理论及实现过程。分析方法采用节点分析法。采用了把一个二端元件定义一支路的概念，这种处理方法在网络分析中具有简单、易于掌握的特点。而在解线性方程时采用大家所熟悉的高斯―约当消去法。在建立方程的过程中采用的是形成Gn，Jn的直接填写法。为使读者理解编写通用程序的思路和方法，使用了大量的流程图。程序能处理含有导纳支路、电流源支路、电压源支路、四种受控源支路及含有互感支路的正弦稳态电路。-sinusoidal AC circuit computer-aided analysis of the theory and implementation process. Analysis using nodal analysis method. Used to bring a two-path components of a definition of the concept of this approach in network analysis is simple, easy-to-understand characteristics. The solution of linear equations used are all familiar with the Gauss-Jordan elimination method. The establishment of the equation used in the process of forming Gn, Jn fill in the direct method. In order to enable readers to understand the procedures for the preparation of general ideas and methods, the use of a large number of flow chart. Procedures can handle containing admittance slip current source slip voltage source slip four controlled source service road and the slip road with mutual inductance sinusoid
