关于LABVIEW的VI生成C代码

这几天测试了一下，使用LABVIEW2015以及C代码生成工具，生成C代码的方法。

感觉VI比较简单，但是对于C代码就表示看不懂了……

LABVIEW的前面板。

以下是LABVIEW的程序。

这个是G代码图。
很简单的一个应用。只是两个数字相加。类型是U8.

执行后，生成了以下几个文件。

在这里，大家一起探讨探讨。。。我表示很难看明白……

大家有可以研究的吗？

只看该作者 · 2016-8-20 15:33

labview是图形语言，你看代码，肯定就会看的迷糊了

看不懂哦！

不过有需要软件著作权申请的，感觉还是很有必要的。

另外CVI 调用LABVIEW还是比较无缝抑制的吧！
