# WDT Example

## Overview

This sample demonstrates the basic watchdog flow.

Source file:

```bash
src/rtsmart/examples/peripheral/wdt/test_wdt.c
```

## Sample Behavior

- set timeout
- start the watchdog
- feed it periodically
- either stop it or keep it running when the process exits

## Key APIs

- `wdt_set_timeout()` / `wdt_get_timeout()`
- `wdt_start()` / `wdt_stop()`
- `wdt_feed()`

## Build and Run

```bash
cd src/rtsmart/examples/peripheral/wdt
make
./test_wdt <timeout_sec> [--no-stop]
```

Examples:

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