Embedded Wizard GUI Demos
If you just want to run our GUI demos on your RZ/A1H Display It board without building the different examples, you can simply flash the binary file of the Embedded Wizard Master Demo.
The Embedded Wizard Master Demo combines a variety of examples within one huge demo application. It can be used for presentations and showcases. Each demo application can be activated from a common main menu. To return back from a demo application to the main menu, a small home button appears on top of every demo. Additionally, the Master Demo contains an auto-demo mode that presents one demo application after the other. The auto-demo starts automatically and stops as soon as the user touches the screen.
In order to flash the binary file to your target, please follow these steps:
★Connect the J-Link LITE adpater with your development board and with your PC via USB.
★Set the DIP switches SW6 1-6 on the RZ/A1H Display It board to: OFF - ON - OFF - ON - ON - ON
★Take a text editor and open the file FlashMasterDemo.bat that you will find in the subdirectory \MasterDemo. At the beginning of the file, the following environment variable has to be set to the installation path of the J-Link utility:
•JLink_Utility_Path - Absolute path of your installed Segger J-Link utility (Step 3 above).
★Execute the batch file FlashMasterDemo.bat: A console window will appear and the flash tool will download the binary file of the Master Demo.

Exploring the Build Environment
The provided Embedded Wizard Build Environment for RZ/A1H Display It contains everything you need to create, compile, link and flash an Embedded Wizard UI application for the Renesas RZ/A1H target. After unpacking, you will find the following subdirectories and files:
•StartGccBuildEnvironment.bat - This script file is provided to start a windows command line to build your GUI applications for the target. Don't forget to set the path of your installed J-Link utility.
•\Application - This folder contains ready-to-use projects to compile and link an Embedded Wizard generated UI application. They are used for all provided examples and they can be used to build your own UI applications.
•\GeneratedCode - This folder is used to receive the generated code from an Embedded Wizard UI project. All template projects are building the UI application out of this folder. You can create your own UI project and generate the code into the subdirectory \GeneratedCode without the need to adapt the project.
•\Project - This folder contains the prepared projects for GCC (make) and Renesas e2 Studio.
•\Source - This folder contains the files main.c and ewmain.c. There you will find the initialization of the system and the main loop to drive an Embedded Wizard GUI application.
•\Examples - This folder contains a set of demo applications. Each example is stored in a separate folder containing the entire Embedded Wizard UI project. Every project contains the necessary profile settings for the Renesas RZ/A1H target. The following samples are provided:
•\HelloWorld - A very simple project that is useful as starting point and to verify that the entire toolchain, your installation and your board is properly working.
•\ColorFormats - This project demonstrates that every UI application can be generated for different color formats: RGBA8888 and RGB565.
•\ScreenOrientation - This demo shows, that the orientation of the UI application is independent from the physical orientation of the display.
•\GraphicsAccelerator - This application demonstrates the graphics performance of the target by using sets of basic drawing operations that are executed permanently and continuously.
•\BezierClock - The sample application BezierClock implements a fancy digital clock and timer application with animated digits. The application uses vector graphics to render dynamically the different digits for clock and timer. The change from one digit to another is handled by moving the vector points to get a smooth transition animation.
•\BrickGame - The sample application BrickGame implements a classic "paddle and ball" game. In the game, a couple of brick rows are arranged in the upper part of the screen. A ball travels across the screen, bouncing off the top and side walls of the screen. When a brick is hit, the ball bounces away and the brick is destroyed. The player has a movable paddle to bounce the ball upward, keeping it in play.
•\ChartsDemo - This application demonstrates the possibilities and the usage of the chart classes LineChart, BarChart and PieChart. The appearance of each chart diagram can be configured easily by using their corresponding properties. Additionally, this demo shows the usage of an outline box to manage scrollable content.
•\ClimateCabinet - The ClimateCabinet demo shows the implementation of a control panel for a climatic exposure test cabinent. The user can define a heating time, a nominal temperature and humidity, a dwell time and the final cooling time.
•\PaperCutter - This demo shows the implementation of a paper cutting machine, where the user can define the pagination and format of the paper as well as the cutting speed and the amount of papers. The application contains many rect effects and fade-in/fade-out effects to change dynamically the layout of the screen.
•\PulseOximeter - The sample application PulseOximeter shows the implementation of a medical device for monitoring a person's pulse frequency and peripheral oxygen saturation. The application demonstrates the usage of vector graphics within graphs and circular gauges.
•\WashingMachine - This demo shows the implementation of a washing machine with a couple of fancy scrollable list widgets to choose the washing program and parameters. The speciality of this sample application is the magnification effect of the centered list items and the soft fade-in/fade-out effects.
•\WaveformGenerator - This WaveformGenerator demo application combines waveforms with different amplitudes and frequencies. The implementation shows the usage of the class Charts::Graph to paint a list of coordinates.
•\MasterDemo - This folder contains the binary file of the Embedded Wizard Master Demo application and a script file to flash the demo on your target. The Master Demo combines a variety of examples within one huge demo application. It can be used for presentations and showcases.
•\PlatformPackage - This folder contains the necessary source codes and/or libraries of the Renesas RZ Platform Package: Several Graphics Engines for the different color formats (RGBA8888 and RGB565) and the Runtime Environment (in the subdirectory \RTE).
•\TargetSpecific - This folder contains all configuration files and platform specific source codes. The different ew_bsp_xxx files implement the bridge between the Embedded Wizard UI application and the underlying board support package (Renesas RZ hardware drivers) in order to access the display or the touch interface.
•\ThirdParty - This folder contains third-party source codes and tools:
•\gcc-arm-none-eabi - This folder contains a subset of the GCC ARM embedded toolchain to compile the examples.
•\Make - This folder contains a make tool to build the entire GUI application via command line.
•\Renesas - This folder contains the necessary Renesas RZ/A1H software used for the Embedded Wizard UI applications (BSP, drivers, FreeRTOS).
•\TLSF - This folder contains the memory manager used for the Embedded Wizard UI applications.
Creating the UI Examples
For the first bring up of your system, we recommend to use the example 'HelloWorld':
Example 'HelloWorld' within Embedded Wizard Studio.
The following steps are necessary to generate the source code of this sample application:
★Navigate to the directory \Example\HelloWorld.
★Open the project file HelloWorld.ewp with your previously installed Embedded Wizard Studio. The entire project is well documented inline. You can run the UI application within the Prototyper by pressing Ctrl+F5.
★To start the code generator, select the menu items - or simply press F8. Embedded Wizard Studio generates now the sources files of the example project into the directory \Application\GeneratedCode.
Compiling, Linking and Flashing
The following steps are necessary to build and flash the Embedded Wizard UI sample application using the GCC ARM embedded toolchain:
★Navigate to the top level of the Build Environment.
★Open StartGccBuildEnvironment.bat - as a result, a windows command line window should open. In case there are error messages, please edit the file and double-check the path settings.
★Now start compiling, linking and flashing:
If everything works as expected, the application should be built and flashed to the Renesas RZ/A1H target.
Example 'HelloWorld' running on RZ/A1H Display It board.
All other examples can be created in the same way: Just open the desired example with Embedded Wizard Studio, generate code and rebuild the whole application using simply:
Creating your own UI Applications
In order to create your own UI project suitable for the Renesas RZ/A1H target, you can create a new project and select the RZ/A1H Display It project template:
As a result you get a new Embedded Wizard project, that contains the necessary Profile attributes suitable for the RZ/A1H Display It board:
The following profile settings are important for your target:
★The attribute PlatformPackage should refer to an installed Renesas RZ Platform Package.
★The attribute ScreenSize should correspond to the display size of the RZ/A1H Display It board.
★The attribute OutputDirectory should refer to the \Application\GeneratedCode directory within your Build Environment. By using this template, it will be very easy to build the UI project for your target.
★The attribute CleanOutputDirectories should be set to true to ensure that unused source code within the output directory \Application\GeneratedCode will be deleted.
★The attribute PostProcess should refer to \Application\Project\e2 Studio\RZA1H-DisplayIt\e2_ Studio_ew_post_process.cmd if you are working with Renesas e2 Studio. In case of the GCC ARM embedded toolchain leave it blank.
Now you can use the template project in the same manner as it was used for the provided examples to compile, link and flash the binary.
After generating code, please follow these steps, in order to build your own UI application:
★Start the batch file 'StartGccBuildEnvironment.bat'. Again, a windows command line window should open.
★Start compiling, linking and flashing:
Most of the project settings are taken directly out of the generated code, like the color format or the screen orientation. Only a few additional settings can be configured directly within the Makefile, like the usage of double buffering.
In order to receive error messages or to display simple debug or trace messages from your Embedded Wizard UI application, a serial terminal like 'Putty' or 'TeraTerm' should be used.
★As soon as you connect your Renesas RZ/A1H target with the PC, using a second USB cable connected to CN18, a RSK USB Serial Port (COMx) appears within your system device list. Open the device manager to get the number of the installed COM port.
★Now you can open your terminal application and connect it via COMx with the following settings: 115200-8-N-1
This terminal connection can be used for all trace statements from your Embedded Wizard UI applications or for all debug messages from your C code.
Using Renesas e2 Studio
If you want to use the Renesas e2 Studio toolchain instead of the GCC ARM embedded toolchain, please follow these instructions:
The subdirectory \Application\Project\e2 Studio contains a template project that is commonly used for all provided Embedded Wizard examples. All Embedded Wizard examples will store the generated code within the common /Application/GeneratedCode folder.
The following steps are needed to establish this automatic project import:
★Open the desired Embedded Wizard example project.
After the Embedded Wizard code generation the installed post process will adapt the .cproject XML file. All necessary libraries and include paths (depending on the color format and screen rotation) will be set automatically.
The given e2 Studio example under \Application\e2 Studio contains a workspace which has all adaptions for an Embedded Wizard project. For using this within Renesas e2 Studio do following steps:
★Open Renesas e2 Studio and select the directory \Application\Project\e2 Studio as workspace directory.
★To import the C project, select the menu item File - Import and choose General - Existing Projects into Workspace and press Next.
★Choose Select root directory - Browse and select the directory \Application\Project\e2 Studio\RZA1H-DisplayIt.
★To compile the project select Project - Build Project.
★Open the Debug Configuration under Run - Debug Configurations... and select Renesas GDB Hardware Debugging - RZA1H-DisplayIt BUILD. Then press Debug.
If the color format or the screen orientation was changed, please do a clean in Renesas e2 Studio.
