1、单向通信 向甲方连续不断地发送变量a的值，未按键，a=0x0f，按键后根据按键确定a值；并将a的值取反从P0口输出，控制D0、D1、D2、D3相应点亮。乙方接收到数据并偶校验正确后，将接收数据取反从P0口输出，控制D0、D1、D2、D3相应点亮。 2、双向通信 甲方连续不断地发送变量a的值，未按键，a=0x0f，按键后根据按键确定a值；乙方未按键不发送，按键后将乙方按键得到的a*16发送；甲乙双方都将发送数据与接收数据相或后再取反，从P0口输出控制D0—D7相应点亮。 3、间隔发送 未按键，甲方不发送数据，按键后甲方每隔50ms连续发送4个字节：0xff、a、a、a。 乙方只在收到甲方数据0xff后的3个数据并验证相同时，才将接收数据*16发送。 甲乙双方都将发送数据与接收数据相或后，从P0口输出控制D0—D7相应点亮。(1. One-way communication The value of variable a is continuously sent to Party A without key, a = 0x0f. After the key is pressed, the value of a is determined according to the key; and the value of a is output from P0 port to control the corresponding lighting of D0, D1, D2 and D3. After receiving the data and checking it correctly, Party B will output the received data from P0 port and control D0, D1, D2 and D3 to light up accordingly. 2. Two-way communication Party A continuously sends the value of variable a without key, a = 0x0f, and determines a value according to the key after the key; Party B does not send the key without key, and sends the a*16 obtained by the key after the key is pressed; Both parties will send the data to or from the receiving data, and then retrieve the data and control D0-D7 from the P0 port to light up accordingly. 3. Interval Sending Without keys, Party A does not send data. After keys, Party A sends 4 bytes continuously every 50 ms: 0xff, a, a.)

基于PSCAD软件的DFIG仿真模型，单机无穷大系统供电(The simulation model based on PSCAD. For the system side uses the infinite-bus)

一款简单的计算器的源代码，代码结构简单，通俗易懂，方便操作，功能齐全，是一个非常简单计算器，很有参考价值，对于初学者，也不难看懂程序，容易掌握C++编程流程，有分数类，有成员函数，析构函数等等，是包含各种基础知识的好例子。关于MFC的知识也包含非常全面，可以轻而易举地掌握C++工程语言。

Jsp批量上传音乐文件，带定时播放功能，添加要播放的音乐可以批量上传，在上传音乐文件时，只能上传格式为mp3的音乐文件，并且单个音乐文件的大小不能超过10M，整个批量音乐文件的大小不能超过100M。在上传过程中，可以实时查看每个文件的上传进度，及整个批量文件上传的情况。点击开始上传，则等待上传的结果，当有音乐文件后，可以根据自己的需要，去设置播放的开发时间及播放的时长，找到系统的sysinit.txt文件。

基于MSP430单片机LaunchPad部分的知识，对于搞单片机的朋友有非常大的帮助，而起程序含注释，易懂(Very large part of the knowledge based on MSP430 microcontroller sensor for friends to engage in automatic control, the sky program containing the annotations, to understand)
