EFM32LG-STK3600 Leopard Gecko¶

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.

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 following 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¶

Debugging - “1-click” solution for debugging with a zero configuration.

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.
