毕业设计时做DC600V逆变器测试系统，采用工控机为主控制器，PCL-818数据采集卡， VC++作编程工具，对25T、25k型客车使用的逆变器进行性能测试。(Graduation time to do DC600V inverter test system, IPC-based controller, PCL-818 data acquisition card, VC++ as a programming tool, 25T, 25k bus-type inverter used for performance testing.)

本程序是虚拟示波器，可以显示多条曲线波形，调节幅值和时间(Oscilloscope can display multiple curve )

液晶240*128驱动 用的是PIC单片机 但是可以改 51单片机 里面驱动都一样 就是 拿过来就可以用 (LCD 240* 128 drive using a PIC microcontroller, but can be changed inside the microcomputer 51 is to take over the same driver can be used)

基于430的DC_DC变化，采用PID控制，调节PWM的输出占公比，从而反馈调节输出电压(Based on 430 DC_DC change, using PID control, adjust the PWM output accounted common ratio, thus regulating the output voltage feedback)

水循环系统、温度信号采集系统、制冷及制热系统、内嵌体温调节算法的温度主控单元软件编写，基于atmega128(Water cycle system, temperature signal acquisition system, cooling and heating system, inline thermoregulatory algorithm of temperature control unit writing software, based on the atmega128 )

DIYMP3，能智能播放，很好的运用了STM32系统相关知识，花费了我将近半年的努力，基本上包含了STM32所有功能的应用。(DIYMP3, play to intelligence, very good use of the STM32 system related knowledge, it took me about half effort, basically contains all STM32 function application.)

温湿度检测 AM32101温湿度传感器 可以检测(Temperature and humidity sensor temperature and humidity testing AM32101)

MODSCAN32英文版， 很好用的。(MODSCAN English, very good use.)
