Smart Utility

Solutions for More Efficient Development

Each Smart Utility takes the form of a single plug-in for the integrated development environment. This group of utilities extends your development environment for greater convenience and can be used whatever the kind of application you are developing.



We have added a [Context Help] tabbed page to the Smart Browser to provide information on possible solutions to problems. This tabbed page enables automatic searching for FAQs and for posts on the Renesas Rulz site related to errors displayed in the error dialog box, and does this immediately without requiring a dedicated Web browser.

Product Lineup

The product has five features for more efficient development.


Smart Configurator

The Smart Configurator is a utility for combining software as you wish. It supports the following three functions related to the embedding of Renesas drivers in your systems.


  • Importing middleware in the form of FIT (Firmware Integration Technology) modules
  • Generating driver code
  • Setting pins

Smart Manual

Smart Manual makes it easy to find a hardware manual or information on the registers of a Renesas device(Note1).
The [Smart Manual] view is for browsing through hardware manuals and searching for occurrences of the names of registers(Note2) or keywords(Note3) in the manual.
The smart manual features also include popping up a description of the specifications in response to placing the mouse cursor over a register name or API function name(Note4) while editing.



  1. Some devices are not supported.
  2. Information on the registers and bits of peripheral I/O is searchable.
  3. Topical key words are used in searching for manuals.
  4. Output functions by a code generator (for RX and RL78 devices), FIT modules (for RX devices), and service calls to Renesas real-time OS (RI600V4), which are only available in e² studio.


Smart Browser

With the Smart Browser, you can easily find and display the latest Renesas hardware manuals, technical updates, and application notes from within the e² studio or CS+. It is also able to download sample code and import projects from projects which include sample code.

In CS+, searching for FAQs that match keywords you have entered is also possible.



Assistant for Optimization

The assistant for optimization assists in optimizing amounts of executable program code. This tool lets you easily see the changes in code size produced by changing compiler and linker options for building, so can help by shortening the time needed to reduce amounts of code.



Open-source plugins that are useful in development

The e² studio also supports plugins which are useful for any development, such as for managing problems, version control, code reviews, and developing documentation. (Note1)


  • Trac for managing bugs and requirements
  • Subversion and Git for version and configuration control (Note2)
  • AgileReview for code reviews
  • Doxygen for developing documentation
  • Jenkins for build management
  • CUnit and Unity for testing



  1. The above open-source tools can be found on their respective official download pages. Refer to the relevant page for the license conditions of each. Note that Renesas assumes no responsibility for failures of or other problems with this software.
  2. Those that can be run from a Windows Explorer window can also be run from the CS+ project tree (e.g. version management tools).

Below you will find information to support the development of your application.
