The STM8S discovery is an evaluation board for the STM8 MCU.

As with all STM evaluation boards there is lengthy list of restrictions in place regarding what you can and can't do with an evaluation board. See this document.

The licensing is complicated and suggests that we can develop programs on the board but only publish them for a finished product. Nothing more complicated then a LED demo can be found on this site.

Install STM8Flash and SDCC.
