ST STM8

Registry:

https://registry.platformio.org/platforms/platformio/ststm8

Configuration:

platform = platformio/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.

For more detailed information please visit vendor site.

Examples

Examples are listed from ST STM8 development platform repository:

• spl-uart-loopback

• spl-blink

• arduino-fade-all-pins

• native-blink

• spl-uart-simple-printf

• spl-flash

• arduino-internal-lib

• arduino-ping-hc04

Debugging

Debugging - “1-click” solution for debugging with a zero configuration.

Tools & Debug Probes

Supported debugging tools are listed in “Debug” column. For more detailed information, please scroll table by horizontal. You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions.
