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 disco_l152rb ID for board option in “platformio.ini” (Project Configuration File):
[env:disco_l152rb]
platform = ststm32
board = disco_l152rb
You can override default ST STM32LDISCOVERY settings per build environment using
board_*** option, where *** is a JSON object path from
board manifest disco_l152rb.json. For example,
board_build.mcu, board_build.f_cpu, etc.
[env:disco_l152rb]
platform = ststm32
board = disco_l152rb
; change microcontroller
board_build.mcu = stm32l152rbt6
; change MCU frequency
board_build.f_cpu = 32000000L
ST STM32LDISCOVERY supports the next uploading protocols:
jlink
stlink
blackmagic
Default protocol is stlink
You can change upload protocol using upload_protocol option:
[env:disco_l152rb]
platform = ststm32
board = disco_l152rb
upload_protocol = stlink
PIO Unified Debugger - “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 STM32LDISCOVERY has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.

Description |
|---|---|
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. |
|
The libOpenCM3 framework aims to create a free/libre/open-source firmware library for various ARM Cortex-M0(+)/M3/M4 microcontrollers, including ST STM32, Ti Tiva and Stellaris, NXP LPC 11xx, 13xx, 15xx, 17xx parts, Atmel SAM3, Energy Micro EFM32 and others. |
|
The ST Standard Peripheral Library provides a set of functions for handling the peripherals on the STM32 Cortex-M3 family. The idea is to save the user (the new user, in particular) having to deal directly with the registers. |

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. |
