ST Nucleo L412RB-P

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_l412rb_p ID for board option in “platformio.ini” (Project Configuration File):

[env:nucleo_l412rb_p]
platform = ststm32
board = nucleo_l412rb_p

You can override default ST Nucleo L412RB-P settings per build environment using board_*** option, where *** is a JSON object path from board manifest nucleo_l412rb_p.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:nucleo_l412rb_p]
platform = ststm32
board = nucleo_l412rb_p

; change microcontroller
board_build.mcu = stm32l412rbt6p

; change MCU frequency
board_build.f_cpu = 80000000L

Uploading

ST Nucleo L412RB-P supports the following uploading protocols:

  • blackmagic

  • cmsis-dap

  • jlink

  • mbed

  • stlink

Default protocol is stlink

You can change upload protocol using upload_protocol option:

[env:nucleo_l412rb_p]
platform = ststm32
board = nucleo_l412rb_p

upload_protocol = stlink

Debugging

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).

ST Nucleo L412RB-P has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.

Description

CMSIS

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

STM32Cube

STM32Cube embedded software libraries, including: The HAL hardware abstraction layer, enabling portability between different STM32 devices via standardized API calls; The Low-Layer (LL) APIs, a light-weight, optimized, expert oriented set of APIs designed for both performance and runtime efficiency
