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

新编MCS-51单片机应用 完本。 希望对大家有用(New MCS-51 microcontroller applications complete this. I hope useful)

此为51单片机的正弦波产生c程序，可将hex文件烧录到单片机内使用。(This is a 51 microcontroller sine wave generator c program, you can burn the hex file into the MCU.)

单片机虚拟串口仿真图，里面有虚拟串口软件和串口调试助手，还有用proteus进行的仿真图，不用开发板一样进行仿真，只能说proteus太强大了。只要你想不到的，没有他做不到的！(Virtual serial port emulation chip chart, which has a virtual serial port software and serial debugging assistant, as well as performed with proteus simulation map, not the same simulation development board can only say proteus too strong. As long as you think, no he can not do!)

交通灯数码管显示4*4键盘修改时间~带仿真图和源代码 模块化编写(Traffic lights digital display 4* 4 keypad to change the time ~ with simulation diagram and source code modular writing)

MultiThread DB - ADO CMTDaoDatabase CMTDaoRecordset

利用定时器产生PWM，使LED灯由亮到灭，由灭到亮逐步变化( Use timer produce PWM, make the light to destroy LED lamp, the gradual change to light out )

MDK RTX51 开发51单片机，使用RTX，对于初始学者很方便(MDK RTX51 )

电脑鼠底层驱动，能实现曲线转弯，速度快，很平稳(Computer mouse driver, can realize curve curve, speed, very smooth )

SD卡2.0协议的详细资料，可用与SPI使用(The details of the SD card 2.0 protocol can be used with SPI)
