数字化变电站保护IED模型文件编辑工具，老外免费软件，很好用。(Digital Substation IED protection model file editing tool, foreigners free software, easy to use.)

在进行图像处理相关DSP编程时，需要移植opencv到CCS平台。作者提供了将Opencv（1.0版本）的cxcore函数库移植到CCS的静态链接库cxcore.lib，以及其生成工程，该例程经作者编译听通过（ccs3.3版本）。由于工程中产生的obj文件和lib文件太大，在工程中已经将其删除，读者在使用时，只需要对工程重新编译即可。最后将生成的cxcore.lib添加到CCS的工程中即可（不要忘了添加相应的头文件），由于cxcore.lib一般和cv.lib配套使用，读者在下载cxcore.lib时也一并将cv.lib下载。作者也提供了将cv.lib与cxcore.lib添加到工程中的实验例程，并且该例程编译通过。也希望读者在该论坛找到该例程将其一并下载，配合使用。(During image processing DSP programming related, it is necessary to transplant opencv CCS platform. The authors provide the Opencv (1.0 version) of cxcore CCS library ported to the static link library cxcore.lib, as well as its generation project, the routine is compiled by the author to listen through (ccs3.3 version). As the project has generated obj files and lib file is too large, the project has been to remove it, the reader is in use, only need to recompile the project. Finally, the resulting cxcore.lib added to the CCS project can (do not forget to add the appropriate header files), as cxcore.lib general and cv.lib supporting the use of the reader and download cxcore.lib when a cv . lib download. The author also provides a cv.lib cxcore.lib added to the project with the experimental routine, and the routine compile. I hope readers find in this forum and download one of the routine, with the use.)
