串口实时窗口的目标

你好,
我写了一个函数来处理串行端口。我可以打开和关闭串口,读和写。阅读和写作需要改进和格式化,但这不是这样的一个大问题,不急。
我从来没有写一个函数,使用过RTWT。我的知识在Matlab / Simulink是万博1manbetx不太好,但是我给我最好的。
我在做一个项目在德国上大学。这个项目是建立一个自主车辆和个人电脑之间的通信。PC应当规范车辆使用仿真软件。万博1manbetx通过XBee-Modules无线电通信发生。优先级越高的部分是开发的监管。
规定必须在实时Windows-Target。我使用Windows 7专业x64和MATLAB R2013a。
这是我的代码:

这将是伟大的,如果有人可以帮助我工作RTWT中的代码。
许多感谢和问候

你不能使用Windows功能实时代码。这包括
它仅仅
,
ReadFile
,
WriteFile
,
CloseHandle
等。你不应该包括
windows.h
在实时代码。
访问串口Real-Tine Windows目标,请使用
数据包输入
和
包输出
块和

现在有一个有趣的现象发生。当我直接输出串行数据终端,一切工作正常,没有错过字节。但同样的微控制器之间的扫兴。在另一项实验中,我使用写入文件(从MATLAB命令空间)发送相同的串行数据(164字节的数组)的微控制器,错过了一些字节。然后我每个字节分别发送,使用一个for循环,这次工作。现在我想的问题是随着微控制器本身。
