Watchdogs are a critical and important component in developing a robust and fail-safe embedded system. In many circumstances, I run into development teams that either have not fully thought through their watchdog strategy or have their watchdog disabled. In order to improve system robustness and ensure that the watchdog can detect a system fault, here … Continue reading Tips and Tricks for Watchdog Design
