WDT Example

Introduction

This example demonstrates the basic watchdog flow: setting timeout, starting, periodic feeding, and stopping or keeping running on exit.

Source location: src/rtsmart/examples/peripheral/wdt/test_wdt.c

Example Behavior

• Set timeout duration (1~60 seconds)

• Start WDT and periodically call wdt_feed()

• On Ctrl+C exit:

  • By default, execute wdt_stop()

  • If --no-stop is passed, only feed the dog before exit without stopping

Key Interfaces

• wdt_set_timeout() / wdt_get_timeout()

• wdt_start() / wdt_stop()

• wdt_feed()

Build and Run

cd src/rtsmart/examples/peripheral/wdt
make

Run:

./test_wdt <timeout_sec> [--no-stop]

Example:

./test_wdt 5
./test_wdt 10 --no-stop

For WDT interface details, please refer to the WDT API Documentation.
