51单片机的学习，8*8点阵的有关程序编程(51 MCU learning, about 8* 8 dot matrix programming)

c51单片机的sle4442卡的读写加密验证程序 已通过(c51 microcontroller sle4442 card reader encrypted authentication procedure has been adopted)

IEEE14节点模型，PSCAD案例，同步发电机功率60MW，电压等级230kV(IEEE14 node model, PSCAD case, synchronous generator power 60MW, the voltage level of 230kV)

基于ARM的俄罗斯方块设计，本次将设计实现一个用C语言编写的、在基于ARM核心的ADuC7020 ARM开发板上实现的单机版的俄罗斯方块小游戏。使用Keil3编程软件对C语言代码进行编写，支持按键操作，在实现过程中涉及了LCD液晶屏的图形显示、按键控制、LED控制、中断、蜂鸣器等嵌入式的编程技术。(Tetris ARM-based design, this will be designed to achieve a C language, the ADuC7020 ARM development board ARM core-based implementations of stand-alone version of the Tetris game. Use Keil3 programming software code written in the C language, support for key operations involved in the implementation process of the LCD screen graphical display, control buttons, LED control, interrupt, buzzer embedded programming techniques.)

说明：  斯凯mrp开发用的宽字符转换 很有用的 有个头文string.c 和string.h 头文件里有定义(Sky mrp convert wide character to use for development of a useful article string.c head and string.h header files are defined)
