The product generates, uses, and can radiate radio frequency energy and may cause harmful interference to radio communications. There is no guarantee
that interference will not occur in a particular installation. If this equipment causes harmful interference to radio or television reception, which can be
determined by turning the equipment off or on, you are encouraged to try to correct the interference by one or more of the following measures:
• Ensure attached cables do not lie across the equipment.
• Reorient the receiving antenna.
• Increase the distance between the equipment and the receiver.
• Connect the equipment into an outlet on a circuit different from that which the receiver is connected.
• Power down the equipment when not in use.
• Consult the dealer or an experienced radio/TV technician for help.
Note: It is recommended that wherever possible shielded interface cables are used.
The product is potentially susceptible to certain EMC phenomena. To mitigate against them it is recommended that the following measures be undertaken:
• The user is advised that mobile phones should not be used within 10 m of the product when in use.

Renesas RA Family EK-RA6M3G – Quick Start Guide
3. Overview of the Quick Start Example Project
The Quick Start example project demonstrates the graphics manipulation capabilities of the integrated
Graphics LCD Controller and JPEG Decoder modules of the RA6M3 MCU Group using a HMI developed
using emWin, the embedded GUI from SEGGER.
emWin uses the drawing engine (Dave2D) of the RA6M3 to perform operations such as drawing bitmaps,
anti-aliased shapes, and filling rectangular areas. emWin also routes JPEG decoding using the integrated
JPEG Decoder to allow for fast drawing of JPEGs, emWin movie files (EMFs), and AVIs.
The example project HMI consists of four screens. The user can switch between each screen by swiping
left/right or pressing one of the navigation buttons.
3.1 Quick Start Example Project Flow
Figure 2. Quick Start Example Project Flow
4. Running the Quick Start Example Project
This section lists the requirements and instructions to power up the EK-RA6M3G kit and run the Quick Start
example project.
Hardware Requirements
• EK-RA6M3 board
• Graphics Expansion Board
• Micro USB device cable
• A 5 V power source with a USB port
4.1 Connecting and Powering Up the EK-RA6M3G Kit
1. Connect the Graphics Expansion Board to the graphics expansion port (J1) of the EK-RA6M3 board.
Make sure to align the arrows printed on the back of each of the two boards.
2. Connect the micro USB end of the micro USB device cable to any one of the micro USB ports (J6, J10, or
J11) of the EK-RA6M3 board.
3. Connect the other end of this cable to the USB port of the 5 V power supply. The power LED (LED4) on
the EK-RA6M3 board will light up white, indicating that the EK-RA6M3 board is powered on.

4.2 Running the Qui ck Start Example Project
To run the Quick Start example project, use the following instructions:
1. On power up or RESET, the Quick Start example project programmed on the EK-RA6M3 board will
begin to execute first showing a splash screen with pictures followed by welcome text.
Figure 3. Splash Screen with Pictures
2. Once the welcome text appears, touch the LCD screen to go to the QR code screen.
Figure 4. Splash Screen with Welcome Text
3. The QR code screen shows the two QR codes generated on runtime with emWin. These codes can be
scanned with a QR code reader such as a cell phone with a QR code scanner app. The QR codes point
to Renesas and SEGGER’s websites.

4. Swipe towards left (or press the navigation arrow on the top right corner of the screen) to navigate to the
alarm screen.
Figure 6. Clock Screen
5. The alarm screen shows a simple alarm clock that can be set by swiping the numbers up or down and
started by pressing the Start button. The timer will start to count down, even if the screen is not the
current screen. Once it reaches zero, a small bell will show up in the top right corner. Pressing this bell
will reset the alarm.

6. Swipe towards left (or press the navigation arrow on the top right corner of the screen) to navigate to the
washing machine interface. Or swipe towards right (or press the navigation arrow on the top left corner
of the screen) to navigate back to the alarm screen.
Figure 7. Washing Machine Interface Screen
7. The washing machine interface provides options to select different programs, temperatures, options, and
so forth. It makes use of the JPEG decoder to display the images in the background. This can help save
memory for example, by comparing a JPEG image with a size of ~28 KB to a raw 16-bpp image with a
size of ~200 KB.
8. Swipe towards left (or press the navigation arrow on the top right corner of the screen) to navigate to the
weather forecast screen. Or swipe towards right (or press the navigation arrow on the top left corner of
the screen) to navigate back to the washing machine interface screen.
Figure 8. Weather Forecast Screen
9. The weather screen shows a weather forecast interface. It uses alpha bitmaps which can be drawn in
any color. It also shows 2D splines drawn using emWin.

5. Next Steps
1 To learn more about the EK-RA6M3G kit, refer to the EK-RA6M3G user’s manual and design package
available in the Documents and Download tabs respectively of the EK-RA6M3G webpage at
renesas.com/ra/ek-ra6m3g
2. Renesas provides several example projects that demonstrate different capabilities of the RA MCUs.
These example projects can serve as a good starting point for users to develop custom applications.
Example projects (source code and project files) for EK-RA6M3G kit are available in the EK-RA6M3GExample Projects Bundle. The example projects bund le is available in the Downloads tab of EKRA6M3G webpage.
Download and extract the example projects bundle (xxxxxxxxxxxxxxx-ek-ra6m3g-
exampleprojects.zip) to a local directory on the host PC.
Refer to the list of all example projects (xxxxxxxxxxxxxxx-ek-ra6m3g-exampleprojects.pdf)
available inside the example projects bundle.
Browse to the desired example project (for example: adc_ek_ra6m3g_ep) in the example projects
bundle (xxxxxxxxxxxxxxx -ek-ra6m3g-exampleprojects\ek_ra6m3g\adc\adc_ek_ra6m3g_ep)
For help on using example projects, refer to Example Project Usage Guide.pdf in the RA
Example Repository on GitHub at
examples/tree/master/example_projects. The archived versions of the source code of the example
projects are available the example project repository.

3. The source code of the Quick Start example project is provided by SEGGER at
ra6m3g/. A few additional demo binary files are also provided by SEGGER, some of which are briefly
described as follows.
Movie Demo displays an emWin Movie File (EMF) using the JPEG decoder to decode individual images of
the movie file. The decoded images are drawn with the drawing engine (Dave2D). The values in the top left
corner indicate the Frames Per Second (FPS) and the time required to decode and draw a single image. The
movie files’ desired FPS is 25.
