用PIC12F508实现对红外遥控器的解码，控制另一个单片机的IO口，实现按键功能(With PIC12F508 achieve decoding infrared remote control, the control of another microcontroller IO port to achieve key functions)

STM32,DAC程序，频率和幅度(0~3.24V)可调(STM32, DAC , frequency and amplitude adjustable)

C写的ArcSDE连接添加Feature的类(Add ArcSDE Connection C written in class Feature)

以前做的一个仿真，关于空间矢量控制的，看看能不能给有需要的人！(Ago to do a simulation, on the space vector control, can look to those in need!)

Smart card虚拟读卡器驱动源码，这个很稀少的哦(smart card virtual driver source code.)

oled的显示驱动程序，都是自己写的，可以移植到51，avr stm8都可以使用，(oled display drivers are written in their own, can be ported to 51, avr stm8 can be used,)

说明：  电力系统 导纳矩阵的形成 数据输入按IEEE标准(Power system admittance matrix of the form data input by IEEE standard)
