EFM32 and EFR32 Platform Application Examples

EFM32 32-bit Microcontrollers

Silicon Labs Platform Applications

Version Badge GSDK Badge License badge

This repo contains example projects that demonstrate various applicaitons using the peripherals of Silicon Labs EFM32 and EFR32 parts.

This repository provides both SLCP projects (as External Repositories) and SLS projects as standalone projects, which are configured for development boards.

Requirements

  1. Silicon Labs EFR32 Development Kit
  2. Simplicity Studio 5
  3. Compatible GSDK version that specified in each project's readme file. You can install it via Simplicity Studio or download it from our GitHub gecko_sdk

Working with Projects

  1. To add an external repository, perform the following steps.

    • From Simpilicity Studio 5, go to Preferences > Simplicity Studio > External Repos. Here you can add the repo https://github.com/SiliconLabs/platform_applications.git.

    • Cloning and then selecting the branch, tag, or commit to add. The default branch is Master. This repo cloned to <path_to_the_SimplicityStudio_v5>\developer\repos\

  2. From Launcher, select your device from the "Debug Adapters" on the left before creating a project. Then click the EXAMPLE PROJECTS & DEMOS tab -> check platform_applications under Provider to show a list of Bluetooth example projects compatible with the selected device. Click CREATE on a project to generate a new application from the selected template.

Legacy Projects - Importing *.sls projects

  1. Place the *.sls file(s) to be imported in a folder.

  2. From Simpilicity Studio 5, select File > Import, select the folder containing *.sls file(s). Select a project from the detected projects list and click on Next. Name the project and click Finish.

See Import and Export for more information.

Porting to Another Board

To change the target board, navigate to Project -> Properties -> C/C++ Build -> Board/Part/SDK. Start typing in the Boards search box and locate the desired development board, then click Apply to change the project settings. Ensure that the board specifics include paths, found in Project -> Properties -> C/C++ General -> Paths and Symbols, correctly match the target board.

Documentation

Official documentation can be found at our Developer Documentation page.

Reporting Bugs/Issues and Posting Questions and Comments

To report bugs in the Application Examples projects, please create a new "Issue" in the "Issues" section of this repo. Please reference the board, project, and source files associated with the bug, and reference line numbers. If you are proposing a fix, also include information on the proposed fix. Since these examples are provided as-is, there is no guarantee that these examples will be updated to fix these issues.

Questions and comments related to these examples should be made by creating a new "Issue" in the "Issues" section of this repo.
