子带编码是一种以信号频谱为依据的波形编码方法，首先用一组带通滤波器将输入信号按频谱分开，然后让每路子信号通过各自的自适应PCM编码器（ADPCM）编码，经过分接和解码再复合成原始信号。(In sub-band coding is a waveform signal based on the spectrum coding method using a first set of band pass filters to separate an input signal spectrum, and so that each signal path through the respective adaptive PCM coder (ADPCM) encoding, after tap and then combined into the original decoding signal.)

MSP430下CO2传感器MG811的驱动，附带电路图(The drive file of MG811 on the platform of msp430)

中断在单片机中起到的作用，以及在她的广泛应用(Interruption in the role of the microcontroller, as well as her extensive application)

在STM32F103VGT6上点亮正点屏幕(On STM 32F 103 VGT6, light up the punctual screen)

剔除粗大值，利用3o准则剔除坏值，然后再判断是否还有，把残差，还有其他输出来。(Eliminate gross values)

说明：  c8051f020图片显示 不复杂 可以自己变换图片 第一次写这类的 不太好大家指出(the c8051f020 picture display pictures online to find the program)

说明：  本系统采用下位机负责模拟数据的采集,从51单片机负责采集数据，并应答主机发送的命令，上位机即主机是负责处理接受过来的数字量的处理及显示，主机和从机之间用RS-485进行通信。这样用户可以在上位机上编写各种程序对文件中的数据进行有效查询和分析,有利于工业过程的长期正常运行和检查。该系统采用的是STC89C52单片机，此芯片功能比较强大，能够满足设计要求。(In this system, the lower computer is responsible for the acquisition of analog data, and the 51 single chip microcomputer is responsible for collecting data and answering the commands sent by the host computer. The host computer is responsible for processing and displaying the received digital quantity. The communication between the host computer and the slave computer uses RS-485. In this way, users can write various programs on the upper computer to effectively query and analyze the data in the file, which is conducive to the long-term normal operation and inspection of industrial processes. The system uses STC89C52 single chip microcomputer, which is powerful and can meet the design requirements.)

这个是自己编的流水灯的例子，用汇编写的，可以学习和使用(THIS IS THE SOURCE OF C51 FOR LIUSHUIDENG,USING THE HUIBIAN)

此编成是使用STM32 的DMA读取写入EEPROM内的资料(STM32 DMA read and write EEPROM)
