ST STM8S-DISCOVERY

Contents

Hardware

Platform :ref:`platform_ststm8`: The STM8 is an 8-bit microcontroller family by STMicroelectronics an extended variant of the ST7 microcontroller architecture. STM8 microcontrollers are particularly low cost for a full-featured 8-bit microcontroller.

Microcontroller STM8S105C6T6
Frequency 16MHz
Flash 32KB
RAM 2KB
Vendor ST

Configuration

Please use stm8sdisco ID for :ref:`projectconf_env_board` option in :ref:`projectconf`:

[env:stm8sdisco]
platform = ststm8
board = stm8sdisco

You can override default ST STM8S-DISCOVERY settings per build environment using board_*** option, where *** is a JSON object path from board manifest stm8sdisco.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:stm8sdisco]
platform = ststm8
board = stm8sdisco

; change microcontroller
board_build.mcu = stm8s105c6t6

; change MCU frequency
board_build.f_cpu = 16000000L

Uploading

ST STM8S-DISCOVERY supports the following uploading protocols:

  • serial
  • stlink
  • stlinkv2

Default protocol is stlink

You can change upload protocol using :ref:`projectconf_upload_protocol` option:

[env:stm8sdisco]
platform = ststm8
board = stm8sdisco

upload_protocol = stlink

Debugging

:ref:`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 :ref:`debugging_tools` using :ref:`projectconf_debug_tool` option in :ref:`projectconf`.

ST STM8S-DISCOVERY has on-board debug probe and IS READY for debugging. You don't need to use/buy external debug probe.

Compatible Tools On-board Default
:ref:`debugging_tool_stlink` Yes Yes

Frameworks
