Migrating between Integrated Development Environments


Porting from High-performance Embedded Workshop to the e² studio

Projects that have been created using High-performance Embedded Workshop 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 High-performance Embedded Workshop Project Into an e² studio Project

Projects for RX or SuperH devices created in V.4.07 and later versions of High-performance Embedded Workshop can be converted into projects for the e² studio by importing them to the e² studio.

Note 1: 64bit versions of e² studio (2020-04 or later) don't have project conversion from HEW projects. Please once convert it to CS+ or 32bit e² studio (V7.x).
Note 2: Direct conversion of projects for H8, M16C, and M32C devices into projects for the e² studio is not possible. Use the function for converting projects for use with CS+ to convert the project into a CS+ project for the given microcontroller, and then importing project it to the e² studio.

Projects for H8, M16C, and M32C, convert CS+ project to e² studio


  1. Select [HEW Project] as the source for importing in the [Import] dialog box of the e² studio.
  1. Select [HEW Project] or [HEW Workspace] as the item to be imported, specify [Select Target] and [Debug Hardware], and import the project.
  • Left: Selecting [HEW Project] for [Import] in the [Import] dialog box of the e² studio
  • Right: Selecting [HEW Workspace] for [Import] in the [Import] dialog box of the e² studio

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].
