AN3265
Application note
Handling hardware and software failures
with the STM8S-DISCOVERY
Application overview
This application is based on the STM8S-DISCOVERY. It demonstrates how to use the
STM8S window watchdog (WWDG) and independent watchdog (IWDG) in conjunction with
the clock security system (CSS) to handle software and hardware failures.
Two external pushbuttons are used to simulate malfunctions while the LEDs monitor the
application progress.
Once the STM8S105C6T6 is powered up through an USB cable connected to the host PC,
LED LD2 starts blinking meaning that the programming operation has completed
successfully.
