AN888: EZR32 Quick Start Guide
The EZR32LG, EZR32WG, and EZR32HG Wireless MCUs deliver a high-performance,
low-energy wireless solution integrated into a small form factor package. By combining a
high-performance Silicon Labs EZRadio or EZRadioPRO sub-GHz RF transceiver with
an energy-efficient 32-bit MCU, the EZR32LG and EZR32WG family provides designers
the ultimate in flexibility with a family of pin-compatible devices that scale with
64/128/256 kB of flash and support transceivers. The EZR32HG family provides the high
energy efficiency of the Cortex-M0+ core in a smaller form factor with 32/64 kB flash.
The ultra-low power operating modes and fast wake-up times of the Silicon Labs energy
friendly 32-bit MCUs, combined with the low transmit and receive power consumption of
the sub-GHz radio, result in a solution optimized for battery-powered applications.
The EZR32LG, EZR32WG, and EZR32HG Wireless Starter Kit (WSTK) is a low-cost,
fully featured starter kit that allows designers to evaluate the performance and features
of the EZR32LG/WG/HG device family. The kit will provide all hardware and software
tools needed to develop and debug applications using the EZR32LG, WG or HG low-en-
ergy Wireless MCUs. Hardware tools include an on-board debugger, advanced energy
monitoring, and integrated packet trace, which are all available either over USB or Ether-
net interfaces. The kit is fully supported by Silicon Labs’ software libraries and the kit
board support package (BSP).

2. Running Simplicity Studio for the First Time
2.1 Navigation in Simplicity Studio
Simplicity Studio is built on the Eclipse platform. As such, it is broken up into different “perspectives”, with each perspective allowing
access to a specific set of functionalities. Simplicity Studio starts in the “Simplicity Perspective,” sometimes referred to as the “Home
Screen.”
Figure 2.1. Simplicity Studio's Simplicity Perspective
From the Simplicity Perspective, you can discover devices, configure Simplicity Studio, or navigate to another perspective for applica-
tion development.
The Simplicity Perspective shows large tile icons that represent the various pieces of functionality within Simplicity Studio. When you
are in a different perspective, you will see smaller tile icons in the top right-hand corner of your screen. You can navigate back to the
Simplicity Perspective (or any other perspective) at any time, by clicking on one of the tile icons in the top right-hand corner of your
screen.

2.2 Downloading Packages for Simplicity Studio
By default, Simplicity Studio comes with some core components necessary for development. The real substance of the Simplicity Stu-
dio application is provided in the “Packages” available from the Simplicity Studio update site. Before you begin working with Simplicity
Studio, make sure that you have all packages installed that you need for your development platform. In particular, for the EZR32 family
of products, you will need both the “Wireless” and “EFM Product” packages.
To download packages for Simplicity Studio, click on the [Package
Management]
icon in the top right-hand corner of the Simplicity
Perspective.
Figure 2.3. Packages Management
The Add/Remove Packages window opens and will guide you through the process of updating Simplicity Studio’s packages. You will
need both the wireless package and the EFM SDK package for development on the EZR32 product.
