Page History
This page shows you how to create an RX project. As an example, we use an FPB-RX261 board but you can use any official Renesas RX board.
The Blinky project is also a good way to verify your tools installation before you start diving into more advanced projects.
1. Create Project
Go to "File" >> "New" >> "Renesas C/C++ Project >> Renesas RX"
Select "Renesas CC-RX C/C++ Executable Project" or "GCC for Renesas RX C/C++ Excecutable Project"
Click the "Next" button.
Type in the project name. Do not use spaces.
Click the "Next" button.
In the ”Select toolchain, device & debug settings" window, select your toolchain, target board, and debug configuration.
"Target Device" is auto populated from "Target Board" selection.
Click the "Next" button.
In the "Select Coding Assistant Settings" window, select "Use Smart Configurator".
Click the "Next" button.
In the "Choose a project template" window, select "Bare Metal - Blinky".
This template includes sample application code to blink LED on an official Renesas RX board.
Click the "Finish" button.
2. Change Perspective
If you see the window below, check the "Remember my decision" box and click the "Open Perspective" button.
This opens the Smart Configurator perspective that allows you to configure your project visually.
2.1 Smart Configurator perspective
The project you created appears in the Project Explorer. At the bottom of the Smart Configurator view are the tabs: "Overview", "Board", "Clocks", "System", "Components", "Pins" and "Interrupts". These tabs are useful for configuring the project and adding new FIT modules.
For more information, click the "User's Guide" button.
3. Build Project
The newly created project contains all the necessary drivers and configuration.
It also includes sample application code to blink LED.
The project can be built and debugged.
Go to "Project" >> "Build Project".
You should see your project is built without errors.
4. Download and Debug
This section explains an example of connecting a debugger using the FPB-RX261 board.
4.1 FPB-RX261 board settings
To debug and program with the FPB-RX261, you must set it to Debug on-board mode.
To enter Debug on-board mode, short pins 2 and 3 of the pin header jumper J4.
Then connect the FPB-RX261 to the PC with the USB cable and change the e2studio settings as follows.
4.2 e2studio settings for debugger connection
Select ”Debug Configurtions"
In the "Debug Configurations" window, select
<How to Create LED_Blinky project>
There are two ways to create a project.
- Creating a new LED Blinky project
Please refer here. - Using FPB_RX261_LED_Blinky.zip
How to create a new LED Blinky project
The FPB_RX261_LED_Blinky project was created by selecting [Bare Metal - Blinky] on the "Choose a project template" page when creating a new project.
For information on how to create a project, please refer to the video at the following video.

When creating the FPB_RX261_LED_Blinky project, there are some differences from the video above.
Project name
FPB_RX261_LED_Blinky
Device Settings -> Target Boad
FPB-RX261
<Operation Environment>
IDE : Renesas Electronics e2 studio 2024-07
C compiler : Renesas Electronics C/C++ Compiler Package for RX Family V3.06.00
Board used : FPB-RX261
USB cable (USB Micro-B --- USB Type A) × 1
<Other preparations>
USB cable (USB Micro-B <-> USB Type A) × 1
Windows PC × 1 unit
<LED blinking behavior＞
The FPB_RX261_LED_Blinky Project allows customers to change the blinking frequency of the user LED(LED2) cyclically each time the user switch S1 on the FPB-RX261 is pressed.
Upon power-on, the user LED (LED2) blinks at 1 Hz.After that, each time the user switch S1 is pressed, the user LED (LED2) changes its blinking frequency cyclically from 1Hz to 5Hz to 10Hz to 1Hz…

- Debugger connection with FPB-RX261
Regarding debugger connection, if you are using the FPB-RX261 board to debug the FPB_RX261_LED project, please see below.
Select ”Debug Configurtions"
In the "Debug Configurations" dialog, click "FPB_RX261_LED_Blinkiy HardwareDebug" under "Reness GDB Hardware Debugging".
Select the ”Debugger" tab, set "E2 LiteLight (RX)" in as the "DebuggerDebug hardware" tab.
In Under the "Debugger" tab, in go to the "Connection Settings" tab, set subtab. "Power Target From The Emulator (MAX 200mA200ms)" to , select "No".
Click the "Debug" button.
- FPB-RX261 board settings
To debug and program with the FPB-RX261, you must set it to Debug on-board mode.
To enter Debug on-board mode, short pins 2 and 3 of the pin header jumper J4.
This setting varies depending on the board.
Please refer to the user manual for each board for details.
This procedure allows the user to connect to the debugger and execute the program.
If you see the window below, check the "Remember my decision" box and click "Switch" button.
This switches the view to the Debug perspective and rearranges your panes for easy debugging.
5. Run Project
The following window will appear. In editor pane, source code shows the reset startup code.
Go to "Run" >> "Resume". Execution stops at main(). Go to "Run" >> "Resume" again.
The LED on your board should now be blinking.
