ST STM8S105K4T6 Breakout Board

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.

Microcontroller	STM8S105K4T6
Frequency	16MHz
Flash	16KB
RAM	2KB
Vendor	ST

Configuration

Please use stm8sblack ID for board option in “platformio.ini” (Project Configuration File):

[env:stm8sblack]
platform = ststm8
board = stm8sblack

You can override default ST STM8S105K4T6 Breakout Board settings per build environment using board_*** option, where *** is a JSON object path from board manifest stm8sblack.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:stm8sblack]
platform = ststm8
board = stm8sblack

; change microcontroller
board_build.mcu = stm8s105k4t6

; change MCU frequency
board_build.f_cpu = 16000000L

Uploading

ST STM8S105K4T6 Breakout Board supports the following uploading protocols:

• serial

• stlinkv2

Default protocol is serial

You can change upload protocol using upload_protocol option:

[env:stm8sblack]
platform = ststm8
board = stm8sblack

upload_protocol = serial

Debugging

Debugging - “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 Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

ST STM8S105K4T6 Breakout Board 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.
