ST Nucleo WL55JC¶

Hardware¶

Platform ST STM32: The STM32 family of 32-bit Flash MCUs based on the ARM Cortex-M processor is designed to offer new degrees of freedom to MCU users. It offers a 32-bit product range that combines very high performance, real-time capabilities, digital signal processing, and low-power, low-voltage operation, while maintaining full integration and ease of development.

Configuration¶

Please use nucleo_wl55jc ID for board option in “platformio.ini” (Project Configuration File):

[env:nucleo_wl55jc]
platform = ststm32
board = nucleo_wl55jc

You can override default ST Nucleo WL55JC settings per build environment using board_*** option, where *** is a JSON object path from board manifest nucleo_wl55jc.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:nucleo_wl55jc]
platform = ststm32
board = nucleo_wl55jc

; change microcontroller
board_build.mcu = stm32wl55jc

; change MCU frequency
board_build.f_cpu = 48000000L

Uploading¶

ST Nucleo WL55JC supports the following uploading protocols:

• cmsis-dap

• jlink

• mbed

• stlink

Default protocol is stlink

You can change upload protocol using upload_protocol option:

[env:nucleo_wl55jc]
platform = ststm32
board = nucleo_wl55jc

upload_protocol = stlink

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).

ST Nucleo WL55JC has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
