STM32F103ZET6 实现 从SD卡读取jpg文件并显示在2.8英寸也液晶显示器上，串口可以看到每张图片的显示时间。(STM32F103ZET6 achieve read jpg files SD card and displayed on the LCD display is also 2.8 inches, the serial port can see each picture display time.)

基于pscad的双馈式风机模型的建立，风力发电机实现清洁能源的利用(Doubly-fed wind turbine model based on pscad)

根据设计任务书的要求，本次设计为110kV 变电站电气一次部分初步设计，并绘 制电气主接线图及其他图纸。该变电站设有两台主变压器，站内主接线分为110kV、 35kV 和10kV 三个电压等级。各个电压等级分别采用单母线分段接线、单母线分段带 旁母接线和单母线分段接线(From the guide of engineering design assignment, we have to design primary power-system of 110kV substation and draw main electrical one-line diagram and others. There are two main transformer in the substation in which main electrical connection can be divided into three voltage grades: 110kV, 35kV with 10kV.It deposits sectionalized single bus bar scheme, sectionalized single and transfer bus bar and sectionalized single bus bar scheme per grade.)

可以在液晶显示两个数计算结果，只能进行两个数的计算(The results can be calculated by two numbers in the liquid crystal display)

基于芯片LPC2132的PWM_DAC基本实验(Based on the the chip the LPC2132 s PWM_DAC basic experimental)

类似电脑键盘组合按键触发的功能。利用51单片机实现。有两个独立按键，当把两个独立按键都按下后，蜂鸣器发出“滴”的一声后就停。直到松开任一个按键后，才能重新进行下一次的组合按键触发。(Similar to the function of the keyboard combination of keys. The use of 51 single chip microcomputer. There are two independent buttons, when the two independent buttons are pressed, the buzzer issued a drop of sound after the stop. Until after the release of any key, the next combination of keys can be re trigger. )
