Elektor LoRa Node Core F072C8 (64 kB)

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 elektor_f072c8 ID for board option in “platformio.ini” (Project Configuration File):

[env:elektor_f072c8]
platform = ststm32
board = elektor_f072c8

You can override default Elektor LoRa Node Core F072C8 (64 kB) settings per build environment using board_*** option, where *** is a JSON object path from board manifest elektor_f072c8.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:elektor_f072c8]
platform = ststm32
board = elektor_f072c8

; change microcontroller
board_build.mcu = stm32f072c8t6

; change MCU frequency
board_build.f_cpu = 48000000L

Uploading

Elektor LoRa Node Core F072C8 (64 kB) supports the following uploading protocols:

  • blackmagic

  • cmsis-dap

  • dfu

  • jlink

  • serial

  • stlink

Default protocol is serial

You can change upload protocol using upload_protocol option:

[env:elektor_f072c8]
platform = ststm32
board = elektor_f072c8

upload_protocol = serial

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).

Elektor LoRa Node Core F072C8 (64 kB) 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.
