ST STM32L073Z-EVAL

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 eval_l073z ID for board option in “platformio.ini” (Project Configuration File):

[env:eval_l073z]
platform = ststm32
board = eval_l073z

You can override default ST STM32L073Z-EVAL settings per build environment using board_*** option, where *** is a JSON object path from board manifest eval_l073z.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:eval_l073z]
platform = ststm32
board = eval_l073z

; change microcontroller
board_build.mcu = stm32l073vzt6

; change MCU frequency
board_build.f_cpu = 32000000L

Uploading

ST STM32L073Z-EVAL supports the following uploading protocols:

  • blackmagic

  • cmsis-dap

  • jlink

  • stlink

Default protocol is stlink

You can change upload protocol using upload_protocol option:

[env:eval_l073z]
platform = ststm32
board = eval_l073z

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 STM32L073Z-EVAL has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
