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).

    AN888: EZR32 Quick Start Guide Running Simplicity Studio for the First Time 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.
  • Page 5 AN888: EZR32 Quick Start Guide Running Simplicity Studio for the First Time 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.
  • Page 6 AN888: EZR32 Quick Start Guide Running Simplicity Studio for the First Time 2.3 Updating Simplicity Studio In addition to downloading packages, you can also update the Simplicity Studio core software at any time by clicking the [Update Soft- ware] icon in the top right-hand corner of the Simplicity Perspective. Figure 2.5.
  • Page 7 AN888: EZR32 Quick Start Guide Running Simplicity Studio for the First Time 2.5 Upgrading the WSTK Boards to the Latest Firmware Once you have connected the WSTK boards to the computer, make sure that the boards have the latest WSTK firmware loaded. This is important, as it ensures that the WSTK boards will correctly communicate with the Simplicity Studio software.
