SDK Examples

The Gecko OS SDK includes a growing list of examples demonstrating how to write applications that run on Gecko OS.

Example Apps are available through Gecko OS Studio (GSS) .

After you select a device in GSS, the available examples for the device platform are available through the Projects tab. Choose Clone Example .

You can also browse the following directory in the Gecko OS SDK on disk:

sdk-<platform>/<sdk_version>/applications/gecko_os

For example:

<user_dir>/gecko_os_sdk/sdk-wgm160p/4.0.17-1380/applications/gecko_os .

The SDK is regularly updated, and new example Apps may appear with an update. Check for the latest SDK examples in GSS.

The following list outlines examples for the WGM160P platform.
