To program the STM8S microcontroller, you will need ST-LINK programmer or any compatible programmer supporting SWIM interface. Most common in the field is to use ST-Link USB dongle
You need to connect GND, SWIM and RESET. +5V is optional as long as you power board from the USB
Add https://github.com/tenbaht/sduino/raw/master/package_sduino_stm8_index.json to the board manager
After that you should install sduino from Board Manager
Select STM8S103F3 as target and other necessary settings in the board settings after
Next press Build or Upload button, it should just work
After installing Plarformio IDE, open sample arduino project or native project. Run Build command to install necessary tools and libraries.
Next run Upload: stm8s003-dev-board task if you're using stlinkv2 programmer. Monitor task should give you Serial monitor, as long as you have your board connected via USB as well.
- Firmware samples
- UART
- RGB led (requires library)
- Debugging (it should just work in Plarformio)
