Q:

 Where can I find code examples for the EFM32 microcontrollers?

A: 

Simplicity Studio includes source code for several code examples. Find out how to get access this in Simplicity Studio by following the steps in this article. The examples for the Development Kits are also loaded into the flash memory of the Development Kit, when you do an upgrade of the kit firmware as described here. This allows you to flash the different demos onto the EFM32 on the Development Kit through the kit menu.

Simplicity Studio also contains an "Application Notes" section where you can get access to all application notes for the EFM32 microcontrollers, which also includes source code examples.
