To help third-party developers develop extensions more easily, we provide a predefined template named Default Arduino template, simplifying parts of the development process. With this template, developers can focus only on configuration items required for Arduino extensions.

In short, if you want to develop an Arduino extension, choose this template.

Steps for the template

1. Choose the template

Choose My Plugin > My Extension, click Add extension, select Default Arduino template in the dialog box that appears, and click OK.

2. Set the extension name

Name your extension and click OK.

3. Configure blocks

(1) Basic configuration

The first category and its first block have been added automatically.

Configure the first block.

In Other blocks configuration, enter the code to be executed when the block is running, and select the options for the block.

When block is running (onRun), execute: Generally, this is used to configure the code to be executed in Live mode

In the block options:

• Enlarge gap between two blocks: increases the spacing between this block and its adjacent block in the Blocks area on mBlock 5, which facilitates the grouping of this block
• Default transcoding for scripts in combination with this block: generally indicates that this block is used as an Events block (blocks can be transcoded only when they are put under an Events block
• This block comes with a checkbox for reading value: provides this block with a returned value that can be displayed on the stage in real time (this option is available only for blocks of the numeric and character string types)

(2) Add source file

Click the Add source file tab and drag the library file to the rectangle.

Add the blocks you need and configure them by referring to steps (1) and (2).

Now, an Arduino extension has been created. After saving the blocks, you can click Preview in the upper right corner to preview the extension.

(3) Advanced configuration

If you need to further configure the extension, you can click the Advanced configuration tab to set more information.

(4) Translation settings

You can translate your extension into multiple languages on the Translation settings tab, so that it can be used by users of different countries.

After completing the configuration, you can click Preview in the upper right corner to preview the extension.

For more details about how to configure an extension, see [Arduino] Create an LED Extension (Using the Default Arduino Template).

The universal template on Extension Builder can be used to create any type of extensions. You can use the universal template to create extensions for both devices and sprites.

1. Choose the template

Choose My Plugin > My Extension, click Add extension, select Universal template, and click OK.

2. Set the basic information

Set the basic information of the extension and click OK.

3. Enter the editing page of the extension

Return to the My Extension list and click the Edit button of the extension to be modified.

4. Configure the extension

On the editing page, add blocks and set all the required information for the extension.

After complete the configuration, you can click Preview in the upper-right corner of the page to preview the extension.

Differences between the universal and default Arduino template

• You need to select the platform the extension supports.
• You need to set the devices (or sprites) the extension supports.

• You need to upload source files on the Common code settings tab.
• You need to set the supported transcoding language (Arduino C is set as the default transcoding languange in the default Arduino template).
