Tiny STM103T¶

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 hy_tinystm103tb ID for board option in “platformio.ini” (Project Configuration File):

[env:hy_tinystm103tb]
platform = ststm32
board = hy_tinystm103tb

You can override default Tiny STM103T settings per build environment using board_*** option, where *** is a JSON object path from board manifest hy_tinystm103tb.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:hy_tinystm103tb]
platform = ststm32
board = hy_tinystm103tb

; change microcontroller
board_build.mcu = stm32f103tbu6

; change MCU frequency
board_build.f_cpu = 72000000L

Uploading¶

Tiny STM103T supports the next uploading protocols:

• blackmagic

• dfu

• jlink

• serial

• stlink

Default protocol is dfu

You can change upload protocol using upload_protocol option:

[env:hy_tinystm103tb]
platform = ststm32
board = hy_tinystm103tb

upload_protocol = dfu

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).

Tiny STM103T 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.
