CAN总线实验：按键控制：两块实验板分别下载好程序之后，利用CAN总线相连接。复位后，数码管各段全亮。按下S1--S4任意一个按键可以控制对方数码管的亮灭。(CAN Experiment one-key control: two experiment boards are connected by CAN bus after downloading the program.After reset, the digital tube all bright.Press S1--S4 to control the brightness and extinction of digital tube.)

说明：  6713dsk上的音频口测试程序 发出特定频率的正弦波形 可测试音频口是否损坏等~(I 6713dsk audio on the issue of test procedures specific frequency sinusoidal waveform audio I can test whether the damage ~)

题目：取一个整数a从右端开始的4～7位。 程序分析：可以这样考虑： (1)先使a右移4位。 (2)设置一个低4位全为1,其余全为0的数。可用~(~0<<4) (3)将上面二者进行&运算。 2.程序源代码：(Topic: take an integer a from the right end of the four to seven began. Program analysis: it can be to consider: (1) to make a move to the right four. (2) sets a low four total for the 1, all the rest for 0 of the number. Can be used to (~ 0 < < 4) (3) will above the difference and operations. 2. The source code:)

C# WPF实现的登录界面，用户名和密码框的提示功能(C# WPF realization prompts the login interface, the user name and password box)

简单的实现了服务器和客户端的聊天功能

MQTT连接服务器，定时发布车间信息，收到服务器车间信息请求后，也可以发布车间信息。定时采集机床数据，在界面刷新显示，并通过MQTT按照工厂设备id数据的格式发布至服务器。云端可查看设备状态数据。(MQTT connects to the server and releases shop information regularly. After receiving the information request from the server shop, it can also issue workshop information. Collect machine tool data regularly, refresh it in the interface, and send it to the server through MQTT format according to the ID data of factory equipment. The device status data can be viewed at the cloud end.)
