串口 通讯和选择开关控制继电器

STM32L152VB的AD采集程序，7通道DMA方式采集，通过串口发送到PC，本人查阅多方资料亲自编程测试，可直接用。附带STM32L152VB工程模板，本人根据资料自己建的。(The AD STM32L152VB acquisition program, 7 channel DMA acquisition, through the serial port to send to the PC multi access information, I personally programming test, can be directly used. With STM32L152VB project templates according to the data, I built myself. )

基于单片机AVR-mega16的LCD12864（带字库）的驱动代码，可直接编译使用。(Driver code (with font) can be directly compiled based microcontroller AVR-mega16 of LCD12864.)

单片机虚拟串口仿真图，里面有虚拟串口软件和串口调试助手，还有用proteus进行的仿真图，不用开发板一样进行仿真，只能说proteus太强大了。只要你想不到的，没有他做不到的！(Virtual serial port emulation chip chart, which has a virtual serial port software and serial debugging assistant, as well as performed with proteus simulation map, not the same simulation development board can only say proteus too strong. As long as you think, no he can not do!)

STM32电机库交流感应电机程序，SVPWM矢量控制算法，单电阻三电阻霍尔采样，有无速度传感器均可控制(STM32 Motor AC induction motor library program, SVPWM vector control algorithm, a single three-resistor Hall sampling resistance, with or without speed sensor can be controlled)

AVR汇编示例子程序集合，初学者可以 参考的源代码，上传供大学参考学习。(AVR compile a collection of the sample subroutine, beginners can refer to the source code, upload the University of reference for the study.)

51单片机4路AD采集模块，附件带源码.原理图等(51 MCU 4-channel AD acquisition module, accessory with source code, schematic diagram, etc.)

说明：  通过uart2连接485设备，使用发送数据到modbus设备，采集传感器数据，解析数据后通过uart1发送到上位机，采集光照度和温湿度数据。(STM32F103 series chip is developed with two serial ports)

51单片机读写sd卡程序,包括对手动卡的读取片区，擦除片区，写入片区，51 单片机模拟spi时序对sd卡进行操作(51mcu read and write sd card)

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.)
