1 Setup
Overview:
Getting Started
Procedural Steps
Step 1.1 Open Renesas Eclipse by using the Shortcut on the Desktop:
Step 1.2 When it gives you the option of choosing a Workspace directory, choose:
C:\Workspace
Step 1.3 Once Eclipse is open at the Welcome page, click on the Workbench Arrow
Trang 3Step 1.4 Click File > New and create a new C Project
Step 1.5 Give it a name and select the GNU RX Toolchain Click Next
Step 1.6 Select the most recent version of GNU Toolchain, Segger J-Link and choose RX63NB
Trang 4Renesas e2studio Advanced Features Page 4 of 10 Step 1.7 Use the default settings for the remaining settings
Step 1.8 Your Workspace should now look like this
Trang 52 Hello World
Overview:
Get your blank project to do something useful
Procedural Steps
Step 2.1 Expand out your Project in the Project Explorer and look under the “src” directory for lab1.c (or
your project wizard generated main C file) – open it
Feel free to have a look around at the other files and directories; they were created with the standard
project generator
Step 2.2 Edit the existing project file named lab1.c to replace the existing code with new badly
formatted code (all against the left margin) which prints a text string:
#include <stdio.h>
#include "iodefine.h"
int main( void) {
while (1) {
printf("Hello World! \n");
}
return 0;
}
Step 2.3 Build the project
Step 2.4 Run the application within the GDB simulator (right click on the project in the navigation pane
and select Run As >> Renesas GDB Simulator

3 Editor Features
Overview:
Work with e2studio to modify a project
Procedural Steps
Step 3.1 Highlight the entire main() function and press CTRL+i
This will auto-indent the selected code and tidy it up for you
Step 3.2 Highlight all the code in your main c file Click Tab Click [Shift] Tab
Step 3.3 You can indent whole chunks of code !
Step 3.4 In main() function add a local variable and counter sig1++;
#include <stdio.h>
#include "iodefine.h"
int main(void) {
sig1++;
}
}
Highlight the sig1++; line of code and press CTRL+Space Create a do while loop that counts to 10000 for a simple delay
Note the other auto-complete options that are available for this variable
One it exits the loop, reset sig1 to Zero Press CTRL+B to Rebuild the projects in the workspace
Step 3.5 Click Help > Key Assist to view all available shortcuts and features
These are customizable from Windows > Preferences > General > Editors > Keys
Trang 74 Sections
Overview:
Using e2studio to manage program memory sections
Procedural Steps
Step 4.1 Terminate the previous Debug Session
Step 4.2 Return to the C/C++ Perspective (CTRL+Shift+F8)
Step 4.3 Close Lab1 and Create a New C Project – Lab2
Step 4.4 Once the blank project is created and built, Use Run > Debug to connect to the RDK board
and familiarize yourself with Restart , Step and Resume MCU debug features Be careful not to use RUN which runs and resets the debugger session – not the MCU
Step 4.5 Use Project > Properties or right click your project in the Project Explorer pane and select
Properties
Step 4.6 Navigate to C/C++ Build > Settings
Step 4.7 In the Renesas Tool Settings window, you will see all the available compiler, assembler and
linker options Select Linker / Sections
Step 4.8 Create a New Section at Fixed Address 0xFFFC0E00 called mysection
Trang 8Renesas e2studio Advanced Features Page 8 of 10
Step 4.9 Once your Section has been created, make a new project with the following code to
demonstrate placing a function in a specified area of memory:
Note: Underscores are DOUBLE underscore _ _
#include "iodefine.h"
void myfunction ( void) attribute ((section (".mysection")));
int main( void)
{
}
void myfunction( void)
{
j++;
}
Step 4.10 Build the Project
Step 4.11 Click Run > Debug to connect to the Debugger
Step 4.12 Click Window > Show View > Trace to pull up the Trace window in the Debug Perspective
Step 4.13 Set a Breakpoint in myfunction
Step 4.14 Run the code (Resume) Pay attention to the Stack Trace – it should show you jumping
through memory to your section as it executes code there
Trang 95 Viewing Global Variables
Overview:
Using e2studio to manage program memory sections
Procedural Steps
Step 5.1 Continuing to use the previous lab content, click on the Expressions Tab in the Debug
Perspective
Step 5.2 Expressions are where we show Global variables
Step 5.3 Click “Add new expression” and add j – our Global that is incremented in myfunction()
Step 5.4 Set a breakpoint at j++; by double clicking in the blue gutter next to the source code
Step 5.5 Click Resume and observe the variable j is incremented each time
Step 5.6 Now double click to remove the breakpoint and then right-click on j in the Expressions window
Step 5.7 Select “Monitor in Realtime” then right-click again and click “Add to Chart” – observe the
realtime watch and chart when you Resume code execution
Step 5.8 Create a do while loop around j++; (highlight the variable in source and CTRL+Space)
Step 5.9 Use this to count up to a specific point then reset j Observe a saw-tooth wave in the Realtime
Chart window

6 Libraries and Output Files
Overview:
How to Modify Project options
Procedural Steps
Step 6.1 Switch back to the C/C++ Perspective
Step 6.2 Use Project > Properties or right click your project in the Project Explorer pane and select
Properties
Step 6.3 Navigate to C/C++ Build > Settings
Step 6.4 In the Renesas Tool Settings window, you will see all the available compiler, assembler and
linker options Select Library Generator / Settings
Step 6.5 Newlib = Complete ISO C/C++ Library / Optimized = Subset C only
Pre-built = Object Files only in Project / Project Built = Source Level Debug available
Step 6.6 Choose Optimized, Project Built Library and Rebuild your project – observe the time taken to
build and the ability to debug the printf() in the stdio library from Section 3 of this handout
Step 6.7 Time Left? Open Play…Please try to break Renesas e2studio, but make notes as you do, we
welcome the feedback
