A padder that adds the padding according to the scheme referenced in ISO 7814-4 - scheme 2 from ISO 9797-1. The first byte is 0x80, rest is 0x00.

两篇SCI论文，分别介绍基于形态奇异熵、高阶统计量的输电线路继电保护新方法 涉及形态学、奇异值分解、熵、高阶统计量等算法。(Two SCI-indexed papers respectively introduce two novel transmission line protection methods based on morphology singular entropy and high order statistics. Algorithms relates to morphology, singular value decomposition, entropy and high order statistics.)

使用STM32F103C8T6处理器和OLED显示屏，传感器为IMU AHRS ，实现了串口通信读取数据，并可以使用桌面调试软件读取串口数据。(stm32f103c2t6,oled,imu ahrs)

MAX197 ADC芯片驱动程序，AVR单片机并行接口，实现高精度12位ADC采样(MAX197 ADC MCUdriver)

STM32F103RBT6和W5200网络芯片的服务期端的测试程序，减少了很多不必要的设置，测试更方便(W5200 STM32F103RBT6 and end of service network chip testing procedures, to reduce a lot of unnecessary settings, the test is more convenient)

基于单片机的火车测速系统源程序。利用单片机STC89C52系统实现列车行驶速度测量转换和LCD液晶显示。同时实现列车行驶方向判断和指示，键盘设定速度上下限，当速度超限时给出超速报警提示。(Train speed system based on single chip source, using SCM STC89C52 trains speed measurement system to achieve conversion and LCD display. While achieving the train driving directions judgment and instructions, keyboard set speed limit, when the speed exceeds the limit given speeding alarm.)

采用C语言编写的模糊PID算法，该算法写了详细的注释。。。(Fuzzy PID algorithm C language, the algorithm wrote detailed notes. . .)

有源滤波的介绍，文中详细介绍了几种有源滤波电路图(The introduction of the active filter)
