總結：1、iar是否能打開多個工程
菜單：Project->Add Existing Project(向工作區添加已有的項目）。
如果在Workspace工作空間切換到OverView頁，則打開的這兩個項目就會同時顯示出來。
用Add ExistingProject功能，可以在工作區中添加很多個工程啦。原來是要打開一個新的IAR窗口，再從新窗口中打開工程才行。
而直接雙擊另外一個工程的工程文件則不行。
2、打開一個工程時，出現警告Theproject 'name' contains the unknown tool 'PEMICRO_ID'
網頁搜索結果
ewd文件刪掉試試。或者重新建立一個工程就行或換個文件夾
原因
Alert: The project 'proj_name' contains the unknown tool'Coder'.EW targets: | 78K, ARM, V850 | EW component: | Embedded Workbench & GUI | Keywords: | IAR visualSTATE System, visualSTATE,visualSTATE-generated code | Last update: | September 15, 2009 |
Irritating alert
Every time a specific project is opened, my EW shows thismessage. The project 'proj_name' contains the unknown tool 'Coder'.Background
The project has a reference to a tool from the visualSTATE toolchain. This tool is used for build integration between the VisualState tool suite and the Workbench.
The project has been opened with an EW where the Visual State alsois installed. References has been added for the visualSTATE Codertool to the EW-project file. When now using the project in a PC /installation where there is no visualSTATE installed, then thealert occurs as the tool is missing.
Details on reasons for the alert
One reason for getting the alert is that the project has resentlybeen migrated from an older EW version, where you had thevisualSTATE Demo installed. In your newer installation of the EW,you have not installed the visualSTATE Demo, thus the alert isshown.
Another reason it that your company have a visualSTATE license onone PC, and moving projects to other PCs will also give thisalert.
How to remove the alert | • | Close the project in yourEW.
| | • | You need to edit the .ewp(project) file, so open the file with a text-editor or anxml-editor.
| | • | Search for thestring: coder
| • | Mark the lines surroundingthe line found with coder andmark out to the surrounding pair of lines with and
| | • | These lines shouldnow be marked. Delete them. Coder 0 | | • | Search again for thestring: coder (therewill be one line for each configuration in theproject.) and repeat theabove two steps.
|
| | • | Search one extra time to makesure no reference remains for coder .
| | • | Save and close the .ewpfile.
| | • | You can now reopen theproject in your EW, and the alert will not occur.
|
Second work around (on new PC)
Install the the visualSTATE tool suite before you install theWorkbench, then the message should not occur, but automatic buildintegration between visualSTATE and Embedded Workbench will notwork
