STM32F103TB (20k RAM. 128k Flash)

Hardware

Platform platform_ststm32: 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.

Microcontroller STM32F103TBU6
Frequency 72MHz
Flash 128KB
RAM 20KB
Vendor Generic

Configuration

Please use genericSTM32F103TB ID for projectconf_env_board option in projectconf:

[env:genericSTM32F103TB]
platform = ststm32
board = genericSTM32F103TB

You can override default STM32F103TB (20k RAM. 128k Flash) settings per build environment using board_*** option, where *** is a JSON object path from board manifest genericSTM32F103TB.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:genericSTM32F103TB]
platform = ststm32
board = genericSTM32F103TB

; change microcontroller
board_build.mcu = stm32f103tbu6

; change MCU frequency
board_build.f_cpu = 72000000L

Uploading

STM32F103TB (20k RAM. 128k Flash) supports the following uploading protocols:

  • blackmagic
  • cmsis-dap
  • dfu
  • jlink
  • serial
  • stlink

Default protocol is stlink

You can change upload protocol using projectconf_upload_protocol option:

[env:genericSTM32F103TB]
platform = ststm32
board = genericSTM32F103TB

upload_protocol = stlink

Debugging

piodebug - "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 debugging_tools using projectconf_debug_tool option in projectconf.

STM32F103TB (20k RAM. 128k 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.

Compatible Tools On-board Default
debugging_tool_blackmagic Yes
debugging_tool_cmsis-dap
debugging_tool_jlink
debugging_tool_stlink
