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.
[env:efm32hg_stk3400] platform = siliconlabsefm32 board = efm32hg_stk3400
You can override default SLSTK3400A USB-enabled Happy Gecko settings per build environment using
board_*** option, where
*** is a JSON object path from
board manifest efm32hg_stk3400.json. For example,
[env:efm32hg_stk3400] platform = siliconlabsefm32 board = efm32hg_stk3400 ; change microcontroller board_build.mcu = efm32hg322f64 ; change MCU frequency board_build.f_cpu = 25000000L
SLSTK3400A USB-enabled Happy Gecko supports the next uploading protocols:
Default protocol is
You can change upload protocol using upload_protocol option:
[env:efm32hg_stk3400] platform = siliconlabsefm32 board = efm32hg_stk3400 upload_protocol = mbed
Debugging - “1-click” solution for debugging with a zero configuration.
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.
SLSTK3400A USB-enabled Happy Gecko has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
