PID程序 - 副本

Replace the fs->{rootmnt,root with {mnt,dentry. Put the old values. It can block.

此为单线加密芯片的驱动程序，已调试，可驱动芯片进行加密操作！(This is the driver of single line encryption chip.)

助赢无线发射模块24l01调试程序for xs128(24l01 debugger to help win wireless transmitter module for xs128)

51单片机程序，两个74HC595驱动8位数码管程序，串行输入，3个IO口控制8位数码管动态扫描(failed to translate)

说明：  瞬时频率计算函数,应用于提取特征值,继续其他的算法研究(Instantaneous frequency calculation function)

在51单片机上实现RS485通讯，能够实现与上位机的通信(RS485 mode on 51 single, able to communicate with the host computer)

说明：  用8个发光管演示出8位二进制数累加过程。(With 8 LED demo out eight binary cumulative process.)

说明：  故障指示器；单相接地故障；电流互感器；全波整流有效值电路；单片机(Fault Indicator Single-phase Ground Fault Current Transformer RMS circuit full-wave rectifier SCM)

了解 CAN 总线通信原理，实现利用 CAN 总线完成通信 在进行实验的时候，需要将两块开发板连接 USB 线进行充电，因为利用 CAN 总线进 行通信需要有较高的驱动能力。(Learn CAN bus communication theory, to achieve complete CAN bus communication when carrying out the experiment, you will need two development boards connect the USB cable for charging, because the use of CAN bus communication requires a higher drive capability.)

STC单片机IO口模拟RS232测试程序,Keil Cx51应用开发技术中的程序主要的功能是在利用串口调试工具发送一个8bit的数据，而后单片机接收后把这个数据发送给模拟串口(STC Single-chip analog IO port RS232 test procedures, Keil Cx51 technology application development process is essentially the function is in the use of serial debug tools send an 8bit data, and then after the single-chip receive the data sent to the simulation of serial)
