Migrating between Integrated Development Environments


Porting from CS+ to the e² studio

Projects that have been created using CS+ can be ported to the e² studio environment in either of the following two ways.

Process Convert an Existing Project Create a New Project
Source file registration Automatic Manual
Option setting (Partially) automatic Manual
Source file folder location Automatic No care needs to be taken regarding the file registration location.
Conflict between source files and automatically generated files Files should be modified after a project is created. Care should be taken regarding conflict at manual file registration.

Converting a CS+ Project Into an e² studio Project

CA78K0R (Note1), CC-RL, and CC-RX projects from CS+ can be converted into projects of the e² studio by using the function for importing projects to the e² studio. Please also read Project Conversion between e² studio and CS+, Notes and Tips (PDF | English, 日本語) for descriptions of restrictions on porting projects between CS+ and the e² studio, workarounds for the restrictions, and so on.


  1. Projects for which this compiler was used are converted into CC-RL projects.


  1. Select [Import…] from the [File] menu of the e² studio or the pop-up menu produced by right-clicking in the project explorer pane.
  1. From [General], select [Renesas CS+ Project for CC-RX and CC-RL] or [Renesas CS+ Project for CA78K0R/CA78K0], then click [Next >] in the dialog box of the e² studio.
    (Select [Renesas Common Project File] or [Renesas CA78K0R Project] in 32bit e² studio.)
  1. Specify the project file from CS+ (*.rcpe) to be converted in [Select file] and import the project.
  1. After you have specified the project file, the entry for [Select Target] in the [Import] dialog box of the e² studio is automatically made. Select the debugger to be used from [Debug Hardware] and click on the [Finish] button.

Create a New Project in the e² studio and Register Existing Source Files

  1. Click on [File] -> [New] -> [C Project] in order from the menu bar of the e² studio and create a new C project. This launches the wizard for creating a new project shown right.
  2. Enter the project name in the dialog box and select the toolchain. Click on [Next >].
  1. Specify [Toolchain Version], [Debug Hardware], and [Select Target] and click on [Next >] to go to the next step.
  1. Click on the [Finish] button after setting the required options. This produces a window [Project summary for Tutorial]. Click on [OK] and a project is generated and displayed in the e² studio as in the example on the right.
  1. Select [Import…] -> [File System] to add an existing source file to the project. It is also possible to add new folders or files of source code from [File] -> [New].
