网络编程路由器项目 可以获取通信双方的mac地址，发icmp包进行数据的转发，从而实现不同网段之间的通信。在路由器运行当中还可以打印arp缓存表信息，路由网卡信息、设置过滤ip、打印过滤ip、删除过滤ip等信息。 在路由器项目可以通过ping命令(电脑ping开发板，开发板ping电脑)(The network programming router project can obtain the MAC addresses of both communicating parties and send the icmp packet for data forwarding)

autocad 计算多条多段线长度，命令ap加载插件，命令lenof然后选择多段线进行计算总长度(AutoCAD calculates the length of multi-segment lines, commands AP to load plug-ins, commands lenof, and then chooses multi-segment lines to calculate the total length.)

实验二定时发送程序：复位后，发送板每个大约一秒时间利用CAN总线向接收板发送一个数据（值为发送板数码管显示值），按下按键1，可以暂停或启动发送。 发送板数码管显示值每隔大约一秒增加一（不管按键是否暂停向接收板发送数据）。接收板收到CAN总线接收的值显示在数码管上，初始为0。(Experiment 2 timing sending program: after reset, the sending board USES CAN bus to send a data (the value is the display value of the digital tube of the sending board) to the receiving board for about one second each. Press key 1 to pause or start sending.The display value of sending board digital tube increases by one every about one second (regardless of whether the button is paused to send data to the receiving board).The value received by the CAN bus by the receiving board is displayed on the nixie tube with the initial value of 0.)

最近两天在弄stm32  ADC多路信号采集，主要是采集遥控器摇杆、电位器等的多路信号，经过思考，觉得还是使用DMA方式比较方便，程序现在已经调通，采集6通道的数据，然后通过串口1打印出来，希望能给新手一些帮助。

基于QQ2440 ARM开发板的实时绘制曲线图的QT程序，从ARM板上的串口接收数据后，绘制曲线图形，然后利用网口将数据传输到PC机上。(QQ2440 ARM development board based on real-time rendering of the QT curve procedures, from the ARM on-board serial port to receive data, graphics rendering curve, and then I will make use of network data transmission to a PC machine.)
