This is the GitHub documentation repository for the Gecko SDK. Here you can find documentation for all the software components offered by Silicon Labs for the EFM32, EFR32 and EZR32. It covers the basic software needed for development, with everything from the low-level hardware abstraction layer (HAL) and peripheral drivers to communication stacks and example code.
This documentation is also available within Simplicity Studio by clicking the Documentation tab. For datasheets, reference manuals and other documentation items, download Simplicity Studio or head over to the document library.
Note: The Gecko SDK here is no longer updated, since it's now part of the larger Gecko SDK Suite package. Download Simplicity Studio and use the Update Software button in the Launcher view to access the latest and previous SDK versions.
