pt100高精度测量电路，精度误差小，速度快，arm9 c51均可实现 ，仅供学习 参考(PT100 high precision measurement circuit, precision error is small, fast, C51 ARM9 can be achieved, only for learning reference )

这是利用51单片机设计成的8路抢答器,主持人按下“开始”按键才开始抢答，并亮抢答允许指示灯(Host press the start button to vies to answer first, light and bright vies to answer first allowed.)

计算太阳位置，通过公式！用单片机编译程序！(Calculate the position of the sun through the formula! Microcontroller compiler!)

基于VC++的，以操作文件的方式（CreateFile,WirteFile,ReadFile）来操作串口实现的射频卡门禁系统，实现了包括读卡写卡，寻卡防冲突等功能。(Based VC++ in order to manipulate papers (CreateFile, WirteFile, ReadFile) to operate the serial interface of the RF card access control systems, including the realization of the card reader to write, look for cards anti-collision function.)

AD9851驱动程序，采用串行写入方式，STM32写入频率控制字。(AD9851 driver, using serial write mode, STM32 write frequency control word.)

51单片机加1602显示计算器C语言源码 可以实现加减乘除，有负数计算 (51 MCU plus 1602 display calculator C language source code Can have negative calculation add, subtract, multiply and divide.)

配电网零序电流故障定位方法在PSCAD中的模型搭建，可以调整故障类型和短路电阻等进行故障模拟(The fault location method of zero sequence current in distribution network is built in PSCAD, which can adjust the fault type and short circuit resistance. )

电机控制的第一手资料，非常全面仔细，可以对伺服控制系统的编码器有很深的了解。(Firsthand motor control, very comprehensive carefully servo control system can have a deep understanding of the encoder.)
