## Hardware

Platform 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.

Frequency | 48MHz
Flash | 256KB
RAM | 32KB
Vendor | Silicon Labs

## Configuration

Please use `efm32lg_stk3600` ID for board option in “platformio.ini” (Project Configuration File):

    [env:efm32lg_stk3600]
    platform = siliconlabsefm32
    board = efm32lg_stk3600

You can override default EFM32LG-STK3600 Leopard Gecko settings per build environment using `board_***` option, where `***` is a JSON object path from board manifest efm32lg_stk3600.json. For example, `board_build.mcu`, `board_build.f_cpu`, etc.

    [env:efm32lg_stk3600]
    platform = siliconlabsefm32
    board = efm32lg_stk3600

    ; change microcontroller
    board_build.mcu = efm32lg990f256

    ; change MCU frequency
    board_build.f_cpu = 48000000L

## Uploading

EFM32LG-STK3600 Leopard Gecko supports the next uploading protocols:

- `blackmagic`

- `jlink`

- `mbed`

Default protocol is `mbed`

You can change upload protocol using upload_protocol option:

    [env:efm32lg_stk3600]
    platform = siliconlabsefm32
    board = efm32lg_stk3600

    upload_protocol = mbed

## Debugging

PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

EFM32LG-STK3600 Leopard Gecko has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.

Compatible Tools | On-board | Default

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.
