It is the actual code mentioned in the article about STM8 hardware bug that cause EEPROM writing instability issue. Read the article for more info and workaround of the issue.

I found the bug on one of these STM8S development board. To test the code on an actual hardware, you also need a tact switch connecting between pin C3 and ground and a device to read the content of EEPROM.
Board specific code is in firmware.c you can effortlessly port the software to different boards if you want.
