说明：  使用开发板配套的Mini USB线连接到开发板标示“调试串口”字样的Mini USB接口为开发板供电。按下任一按键之后，在PC端硬石上位机串口助手功能可以看到当前转速（圈/s），编码器值，速度的方向代表电机转动的方向(Connect the Mini USB cable supporting the development board to the Mini USB interface marked with "debugging serial port" to power the development board. After pressing the next button, you can see the current speed (coil /s), encoder value and speed direction of the hard stone upper PC serial port assistant function)

基于纯数字电路实现的电子钟，可以设置时分秒(Electronic clock based on pure digital circuit can set time-seconds.)

SAR成像matlab代码，实现三个点目标的成像(SAR imaging matlab code to achieve three point target imaging)

远峰pxa255系列开发板图，标注有各个元器件的功能，可作参考-series of far-pxa255 development map, marked in various parts of the function can be used as a reference

数据滤波是去除噪声还原真实数据的一种数据处理技术, Kalman滤波在测量方差已知的情况下能够从一系列存在测量噪声的数据中，估计动态系统的状态. 由于, 它便于计算机编程实现, 并能够对现场采集的数据进行实时的更新和处理(Data filtering is to remove noise and a data processing technique of real data reduction, Kalman filter can from a series of measurement noise variance in measuring the condition of known data, state estimation of dynamic systems. Because it is convenient for computer programming, and can be collected on the spot data update and real-time processing)

C#实现对数字的加密，这是一个源代码例子，对阿拉伯数字加密，比如可把“123”加密成不可读的特殊字符。在代码中：KeyValue值：录入键区0～9 48～57 数字键区0～9 96～105， End键的KeyValue值：35，并定义了相关的快捷键：如果用户按下了〈Ctrl〉＋〈Shift〉＋〈End〉组合键，则直接退出，录入键区的“1”与数字键区的“1”共享同一操作。。
