STM32F103R8 (20k RAM. 64 Flash)¶

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 genericSTM32F103R8 ID for board option in “platformio.ini” (Project Configuration File):

[env:genericSTM32F103R8]
platform = ststm32
board = genericSTM32F103R8

You can override default STM32F103R8 (20k RAM. 64 Flash) settings per build environment using board_*** option, where *** is a JSON object path from board manifest genericSTM32F103R8.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:genericSTM32F103R8]
platform = ststm32
board = genericSTM32F103R8

; change microcontroller
board_build.mcu = stm32f103r8t6

; change MCU frequency
board_build.f_cpu = 72000000L

Uploading¶

STM32F103R8 (20k RAM. 64 Flash) supports the next uploading protocols:

• jlink

• stlink

• blackmagic

• serial

• dfu

Default protocol is stlink

You can change upload protocol using upload_protocol option:

[env:genericSTM32F103R8]
platform = ststm32
board = genericSTM32F103R8

upload_protocol = stlink

Debugging¶

PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

STM32F103R8 (20k RAM. 64 Flash) 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.
