96Boards Neonkey

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 b96b_neonkey ID for board option in “platformio.ini” (Project Configuration File):

[env:b96b_neonkey]
platform = ststm32
board = b96b_neonkey

You can override default 96Boards Neonkey settings per build environment using board_*** option, where *** is a JSON object path from board manifest b96b_neonkey.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:b96b_neonkey]
platform = ststm32
board = b96b_neonkey

; change microcontroller
board_build.mcu = stm32f411ce

; change MCU frequency
board_build.f_cpu = 100000000L

Uploading

96Boards Neonkey supports the next uploading protocols:

  • blackmagic

  • jlink

  • mbed

  • stlink

Default protocol is stlink

You can change upload protocol using upload_protocol option:

[env:b96b_neonkey]
platform = ststm32
board = b96b_neonkey

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).

96Boards Neonkey 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.

Name

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

Zephyr RTOS

The Zephyr Project is a scalable real-time operating system (RTOS) supporting multiple hardware architectures, optimized for resource constrained devices, and built with safety and security in mind

libopencm3

The libOpenCM3 framework aims to create a free and open-source firmware library for various ARM Cortex-M0(+)/M3/M4 microcontrollers, including ST STM32, Ti Tiva and Stellaris, NXP LPC, Atmel SAM3, Energy Micro EFM32 and others
