WDT | Watchdog Timer Programming | C code for watchdog timer | watchdog timer coding | WDT

Watchdog timer (WDT) programming involves configuring a hardware or software timer to reset a microcontroller if the main application hangs, crashes, or enters an infinite loop. It works by "feeding," "kicking," or "resetting" the timer at regular intervals within the main code loop. If the timer expires (e.g., 2 seconds) without being cleared, it triggers a system reset. Watchdog Timer Programming Steps Initialization/Configuration: Set the timer's timeout period based on the application's maximum expected loop time and enable the watchdog. "Feeding" (Kicking) the Dog: Place the reset command (wdt_reset() or similar) inside the main loop, ensuring it is executed frequently enough to prevent the timeout. System Monitoring: If the code gets stuck in a loop, the "feeding" command is missed, the timer overflows, and the system resets.
