远程聊天写，VS.NET 写的远程聊天室程序

用MFC（C++语言）实现了一个串口调试助手的功能。(Using MFC (C++ language) to achieve a serial debugging assistant function.)

光敏传感器返回值给adc，由lcd显示，AO接PA1，DO接PA4(The return value of photosensitive sensor to ADC is displayed by LCD .AO connects PA1, DO connects PA4 .)

基于STM32的，PID模糊控制系统，PID产生的数值控制PWM产生不同的波形，控制外部元件(Based on STM32, PID fuzzy control system, the numerical control PWM generated by PID generates different waveforms and controls external components.)

此文件是基于stm32单片机的按键扫描程序，能正常实现按键扫描，(Key scanning code based on STM32 microcontroller)

用MFC写的商品管理系统，功能完善，可以增加删除查询修改以及统计商品信息(Written with MFC merchandise management system fully functional, you can add delete modify the query and statistical information goods)

实现避障的基础功能，使用stm32f103rct6板子(this is very good idea!)

使用stm32在KEIL mdk 的环境下 实现压控增益，其中用的DAC7311芯片和OPA830运放(The use of STM32 to achieve the VCO gain in KEIL MDK environment, the use of DAC7311 chip and the OPA830 op amp)

这个程序功能完整，可以给初学者参考使用，感觉不才错-Functional integrity of this process, you can use and reference to the beginners, I feel wrong不才

说明：  小甲鱼数据结构与算法课件+源码，适合初学者学习(Small turtle data structure and algorithm courseware + source code, suitable for beginners to learn)

OFDM下的MIMO模块，可以实现信道估计，而且本程序可以喝C相连接，方便。(OFDM under the MIMO module,channel estimation can be achieved,but this program can drink C is connected and convenient.)
