ST STM8S-DISCOVERY¶

Hardware¶

Platform ST STM8: 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.

Configuration¶

Please use stm8sdisco ID for board option in “platformio.ini” (Project Configuration File):

[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 next uploading protocols:

• serial

• stlink

• stlinkv2

Default protocol is stlink

You can change upload protocol using upload_protocol option:

[env:stm8sdisco]
platform = ststm8
board = stm8sdisco

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).

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