NUCLEO-8S208RB

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	STM8S208RBT6
Frequency	16MHz
Flash	128KB
RAM	6KB
Vendor	STMicroelectronics

Configuration

Please use nucleo_8s208rb ID for board option in “platformio.ini” (Project Configuration File):

[env:nucleo_8s208rb]
platform = ststm8
board = nucleo_8s208rb

You can override default NUCLEO-8S208RB settings per build environment using board_*** option, where *** is a JSON object path from board manifest nucleo_8s208rb.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:nucleo_8s208rb]
platform = ststm8
board = nucleo_8s208rb

; change microcontroller
board_build.mcu = stm8s208rbt6

; change MCU frequency
board_build.f_cpu = 16000000L

Uploading

NUCLEO-8S208RB supports the following uploading protocols:

• serial

• stlinkv21

Default protocol is stlinkv21

You can change upload protocol using upload_protocol option:

[env:nucleo_8s208rb]
platform = ststm8
board = nucleo_8s208rb

upload_protocol = stlinkv21

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).

NUCLEO-8S208RB has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
