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.

Please use rumba32_f446ve ID for board option in “platformio.ini” (Project Configuration File):
[env:rumba32_f446ve]
platform = ststm32
board = rumba32_f446ve
You can override default 3D Printer control board settings per build environment using
board_*** option, where *** is a JSON object path from
board manifest rumba32_f446ve.json. For example,
board_build.mcu, board_build.f_cpu, etc.
[env:rumba32_f446ve]
platform = ststm32
board = rumba32_f446ve
; change microcontroller
board_build.mcu = stm32f446ret6
; change MCU frequency
board_build.f_cpu = 180000000L
3D Printer control board supports the following uploading protocols:
blackmagic
cmsis-dap
jlink
serial
stlink
Default protocol is stlink
You can change upload protocol using upload_protocol option:
[env:rumba32_f446ve]
platform = ststm32
board = rumba32_f446ve
upload_protocol = stlink
Debugging - “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).
3D Printer control board does not have on-board debug probe and IS NOT READY for debugging. You will need to use/buy one of external probe listed below.

The ARM Cortex Microcontroller Software Interface Standard (CMSIS) is a vendor-independent hardware abstraction layer for the Cortex-M processor series and specifies debugger interfaces. The CMSIS enables consistent and simple software interfaces to the processor for interface peripherals, real-time operating systems, and middleware. It simplifies software re-use, reducing the learning curve for new microcontroller developers and cutting the time-to-market for devices |
