Chapter 2. Introduction
This manual is designed to answer, in tutorial form, the most common questions asked about using the Renesas Starter Kit: The tutorials
help explain the following:
•How do I compile, link, download, and run a simple program on the Renesas Starter Kit?
•How do I build an embedded application?
•How do I use Renesas’s development tools?
The project generator will create a tutorial project with two selectable build configurations:
•‘Debug’ is a project built with the debugger support included.
•‘Release’ build demonstrating code suitable for release in a product.
Files referred to in this manual are installed using the project generator as you work through the tutorials. The tutorial examples in this
manual assume that installation procedures described in the Renesas Starter Kit Quick Start Guide have been completed.
Please refer to the Quick Start Guide for details of installation and configuration of the Renesas Starter Kit.
NOTE: These tutorials are designed to show you how to use the Renesas Starter Kit and are not intended as a comprehensive
introduction to the High-performance Embedded Workshop debugger, the compiler tool-chains or the E8a Emulator – please
consult the relevant usermanuals for more in-depth information.

Chapter 3. Tutorial Project Workspace
The workspace includes all of the files for two build configurations. The tutorial code is common to both the Debug and the Release build
configurations. The tutorial is designed to show how code can be written, debugged then downloaded in a ‘Debug’ situation.
The build configuration menu in High-performance Embedded Workshop allows the project to be configured such that certain files may
be excluded from each of the build configurations. This allows the inclusion of the debug monitor within the Debug build, and its
exclusion in the Release build. Contents of common ASM files are controlled with defines set up in the build configuration options and
#ifdef statements within the same files.
Maintaining only one set of project files means that projects are more controllable.

Chapter 4. Project Workspace
4.1. Introduction
High-performance Embedded Workshop is an integrated development tool that allows the user to write, compile, program and debug a
software project on any of the Renesas Microcontrollers. High-performance Embedded Workshop will have been installed during the
installation of the software support for the Renesas Starter Kit product. This manual will describe the stages required to create and debug
the supplied tutorial code.
4.2. Creating a new Project Workspace
Start High-performance Embedded Workshop from the Windows Start Menu, Start ¦ All Programs ¦ Renesas ¦ High-Performance
Embedded Workshop
Openanewtutorialworkspace fromthe[File->New Workspace…]menu orselect ‘Createanew projectworkspace’ whenpresented with
the ‘Welcome!’ dialog.
The example above shows the New Project Workspace dialog with the RSKM37542 selected.
•Select the 740 CPU Family and “Renesas 740 Family Standard” Toolchain.
•Select the “RSKM37542” Project type from the left-hand Projects list.
•Enter a Workspace Name; all your files will be stored within a folder called c:\WorkSpace\<your_name>
•The project name field will be pre-filled to match the workspace name above; you can change this name if you wish.
Note: High-performance Embedded Workshop allows you to add multiple projects to a workspace. You may add the
sample code projects later so you may wish to choose a suitable name for the Tutorial project now.
•Click <OK> to start the Renesas Starter Kit Project Generator wizard.

The next dialog presents the three types of example project available:
1. Tutorial: This is the one of interest at this time; the code is explained later in this manual.
2. Sample code: this provides examples for using various peripherals. If you select this and click <Next> it will open a new dialog
allowing the selection of many code examples for the peripheral modules of the device.
3. Application: where the debugger is configured but there is no program code. This project is suitable for the user to add code
without having to configure the debugger.
•Select “Tutorial” as the type of project to generate and then click <Next>.
•Click <Finish> to create the project
The project generator wizard will display a confirmation dialog. Press <OK> to create the project and insert the necessary files.
A tree showing all the files in this project will appear in High-performance Embedded Workshop.
•To view the file ‘main.a74’, double click on the file in the Workspace window, ‘main.a74’ will appear in the code window.
4.3. Build Configurations and Debug Sessions
Theworkspace thathas beencreatedcontains twobuild configurations and twodebug sessions. The BuildConfiguration allows thesame
project to be built but with different compiler options. The options available to the user are fully described in the High-performance
Embedded Workshop User’s Manual.
4.3.1. Build Configuration
The build configurations are selected from the left hand drop down list on the toolbar. The options available are Debug and Release. The
debug build is configured for use with the debugger. The Release build is configured for final ROM-able code.
A common difference between the two builds may be the optimisation settings. With Optimisation turned on the Debugger may seem to
execute code in an unexpected order. To assist in debugging it is often helpful to turn optimisation off on the code being debugged.
•Select the ‘Debug Build’ Configuration.
4.3.2. Debug Session
The debug sessions are selected from the right hand drop down list on the toolbar. The options vary between Renesas Starter Kit types
howeveronewillalways startDebugandinclude thetypeofdebuginterface,thealternate selectionisthe‘DefaultSession’.The purposeof
the debug sessions is to allow the use of different debugger tools or different debugger settings on the same project.
•Select the ‘Session740_E8a_SYSTEM’ debug
session.

Chapter 5. Building the Tutorial Project
The tutorial projectbuild settings have been pre-configuredinthe tool-chainoptions. Toview the tool chainoptions select the ‘Build’ menu
item and the relevant tool-chain. This should be the first option on the drop down menu.
The dialog that is displayed will be specific to the tool-chain selected.
The Configuration pane on the left hand side will exist on all the
tool-chain options. It is important when changing any setting to
be aware of the current configuration that is being modified. If
you wish to modify multiple or all build configurations this is
possible by selecting ‘All’ or ‘Multiple’ from the ‘Configuration’
drop down list.
•Review the options on each of the tabs and
‘Category’ drop down lists to be aware of the
options available.
Note: For the purposes of the tutorial, leave all
options at default.
When complete close the dialog box by clicking <OK>.
5.1. Building Code
There is a choice of three shortcuts available for building the project.
1. Selecting the ‘Build All’ tool bar button.
This will build everything in the project that has not been excluded from the build. This includes the standard library.
2. Selecting the ‘Build’ tool bar button.
This will build all files that have changed since the last build. The standard library will not be built unless an option has been
changed.
3. Pressing <F7>
This is equivalent to pressing the ‘Build’ button described above.
•Build the project now by pressing <F7> or pressing one of the build icons as shown above.
During the build each stage will be reported in the Output Window.
The build will complete with an indication of any errors and warnings encountered during the build.

5.2. Connecting the debugger
For this tutorial it is not necessaryto provide an external power supply to the board.The power will be obtained from the USBport. Please
be aware that if you have too many devices connected to your USB port it may be shut down by Windows. If this happens remove some
devices and try again. Alternatively provide an external power source taking care to ensure the correct polarity and voltage.
The Quick Start Guide provided with the Renesas Starter Kit board gives detailed instructions on how to connect the E8a to the host
computer. The following assumes that the steps in the Quick Start Guide have been followed and the E8a drivers have been installed.
•Fit theLCDmodule toJ8on theRenesas Starter Kitensuring thatpin1 onthe modulecorrespondstothe indicationon the
Renesas Starter Kit PCB.
•Connect the E8a debugger to the USB port on your computer.
•ConnecttheE8aDebuggerto thetargethardwareensuring thatitispluggedintothe connectormarkedJ6whichisnearest
the power connector.
•If supplying external power to the board this can be turned on now.
5.3. Connecting to the target with the E8a
This section will take you through the process of connecting to the device, programming the Flash and executing the code.
•Select the ‘Session740_E8a_SYSTEM’ debug
session.
•Click the <Connect> button
on the debug toolbar.
•The “Emulator Setting” dialog will be shown.
Select the correct MCU group and device type.
