Murata Type 1LD EVB Development Board

1 – Download MICROEJ SDK

MICROEJ SDK is an IDE built on Eclipse for creating feature-rich applications for MicroEJ Virtual Execution Environment (VEE).

Supported Operating System

MICROEJ SDK runs on the following operating systems: Windows (7–8-8.1-10), Linux, Mac OS X)

A Java™ Runtime Environment 8 is needed on your host computer for running MICROEJ SDK. Download Java™ Runtime Environments

• Go back to MICROEJ SDK.
• Select the Window > Preferences > MicroEJ menu.
• Press Add....
• Browse the previously downloaded activation key archive file.
• Press OK. A new license is successfully installed.
• Go to Architectures sub-menu and check that all architectures are now activated (green check).
• Your MICROEJ SDK is successfully activated. Proceed to the next step.

4 – Create Your First VEE

• You are a C developer.
• You want to create a custom MICROEJ VEE for your target hardware.

• Inside the MICROEJ SDK select File > Import > General > Existing Projects into Workspace and click on Next>.
• Select and browse the previously unarchived folder for a MICROEJ VEE sources file (e.g. [board]-[uid]-platformSource.zip).
• Select all Eclipse projects. Press Finish. The MICROEJ VEE sources are successfully imported.

• Now you need to build it.
• Provided that you installed the MICROEJ Architectures (see. step 2 of this getting started page), open the .platform file in the Murata-Type1LD-EVB-configuration project.
• In the build section of the .platform file, click on Build Platform.
• Wait for the build to finish, a new MurataType1LD-SingleApp-CM3_GCC48-X.X.X project should appear.
• That’s it! You have build your first MICROEJ VEE. Now it is available to execute MICROEJ examples.

For this board you have to install up-to-date drivers for USB Serial and JTAG from Cypress. Follow the installation described here.

5 – AWS IoT Core Example

6 – Bluetooth Example

• Download the following archive Bluetooth Example.
• In the same MICROEJ SDK worspace you imported the MICROEJ VEE sources in.
• Import the project from the previously downloaded archive, File > Import > General > Existing Projects into Workspace and click on Next>.
• Right-click the MicroEJ project com.microej.example.bluetooth.hello.
• Then Run As > MicroEJ Application.
• Choose the Main class.
• Select the MurataType1LD-SingleApp-CM3_GCC48 2.0.0 VEE.
• It will instanciate a Run Configuration, you can stop the simulation.
• Edit the newly created Run Configuration.
• Configure the Execution mode to Execute on Device, Core Engine Default and Settings Build and Deploy
• Click on Run button.
• This will compile the application into the Murata-Type1LD-EVB-bsp project.
• To build and flash the final binary: open the Build Targets view. (Ctrl + 3 in MICROEJ SDK then type Build Targets).
• Execute the snip.microej-MurataType1LD-FreeRTOS-LwIP-SDIO download download_apps run target.
• This will deploy an application that will periodically send a message to devices connecting to the board through Bluetooth.
• To view the message you can use the Bluetooth Companion, an Android application that allows the connection to the ESP32-WROVER and display of such message.
• Download the .apk file here.
• Consult the documentation for installing APK files for your phone.
