全自动可遥控旗帜升降系统以AVR单片机为核心，由PWM对电机进行变频调速，高精度光电编码器测速，闭环式电路控制。能够利用按键输入相应的指令控制旗帜的升降，还可以实现在特定位置停留的功能。利用LCD可以显示旗帜的实时高度和相应的控制命令，用LED指示旗帜是否处于半旗状态，具有语音提示报警功能，并可利用无线模块实现遥控功能，准确均匀地实现旗帜的升降(Automatic landing system can be remote-controlled flag to AVR microcontroller core of the PWM VVVF motor, high-precision optical encoder gun, closed-loop control circuit. Enter the appropriate button to take advantage of the command control of the rise and fall of the flag, but also can stay in the function of a specific location. LCD can display the banner of the use of real-time high and the corresponding control command, the LED is directed at the flag half-mast, and alarm functions with voice prompts, and the use of wireless remote control function module, to achieve uniform and accurate take-off and landing flag)

遗传算法解决TSP旅行商问题（可计算30个城市），用Visual C++编写，希望对大家有所帮助。(Genetic algorithm to solve TSP traveling salesman problem (calculate 30 cities), written in Visual C++, we want to help.)

本程序会将WIFI模块发送的数据转发到USART1串口，同时将USART1串口接收到的数据转发给WIFI模块。这样客户就可以通过HL-340的USB转RS232串口线来测试WIFI模块的AT指令了。(The data in this program will be forwarded to the WIFI module sending USART1 serial port, while forwards USART1 receive serial data to WIFI module. So customers can be transferred via RS232 serial cable HL-340' s USB WIFI AT command to test the module.)
