# Timer Example

## Overview

This sample tests both hardware timers and software timers.

Source file:

```bash
src/rtsmart/examples/peripheral/timer/test_timer.c
```

## Sample Behavior

- create and destroy timers
- configure mode and period
- register callbacks
- start and stop timers
- clean up resources

## Key APIs

- `drv_hard_timer_inst_create()` / `drv_hard_timer_inst_destroy()`
- `drv_hard_timer_set_mode()` / `drv_hard_timer_set_freq()` / `drv_hard_timer_set_period()`
- `drv_hard_timer_register_irq()` / `drv_hard_timer_start()` / `drv_hard_timer_stop()`
- `drv_soft_timer_create()` / `drv_soft_timer_destroy()`
- `drv_soft_timer_set_mode()` / `drv_soft_timer_set_period()`
- `drv_soft_timer_register_irq()` / `drv_soft_timer_start()` / `drv_soft_timer_stop()`

## Build and Run

```bash
cd src/rtsmart/examples/peripheral/timer
make
./test_timer
```
