Silicon Labs EFM32¶
Silicon Labs EFM32 Gecko 32-bit microcontroller (MCU) family includes devices that offer flash memory configurations up to 256 kB, 32 kB of RAM and CPU speeds up to 48 MHz. Based on the powerful ARM Cortex-M core, the Gecko family features innovative low energy techniques, short wake-up time from energy saving modes and a wide selection of peripherals, making it ideal for battery operated applications and other systems requiring high performance and low-energy consumption.
For more detailed information please visit vendor site.
Examples are listed from Silicon Labs EFM32 development platform repository:
PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.
Supported debugging tools are listed in “Debug” column. For more detailed information, please scroll table by horizontal. You can switch between debugging Tools & Debug Probes using debug_tool options.
You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions.
Boards listed below have on-board debug tool and ARE READY for debugging! You do not need to use/buy external debug tool.

|mbed||The mbed framework The mbed SDK has been designed to provide enough hardware abstraction to be intuitive and concise, yet powerful enough to build complex projects. It is built on the low-level ARM CMSIS APIs, allowing you to code down to the metal if needed. In addition to RTOS, USB and Networking libraries, a cookbook of hundreds of reusable peripheral and module libraries have been built on top of the SDK by the mbed Developer Community.|
