# Touch Example

## Overview

This sample demonstrates the RT-Smart touch HAL read flow in two modes:

- reading points from an already registered touch device
- creating the touch device dynamically from configuration, then reading points

Source file:

```bash
src/rtsmart/examples/peripheral/touch/test_touch.c
```

## Sample Capabilities

- print touch events: `DOWN`, `MOVE`, and `UP`
- support multi-touch reads, with a sample buffer size of 5 points
- print device capabilities and current configuration
- support clean exit with `Ctrl+C`

## Key APIs (matching the current code)

- `drv_touch_inst_create()`
- `drv_touch_read()`
- `drv_touch_get_info()`
- `drv_touch_get_config()`
- `drv_touch_get_default_rotate()`
- `drv_touch_inst_destroy()`
- `canmv_misc_create_touch_device()`
- `canmv_misc_delete_touch_device()`

## Build and Run

### Build

```bash
cd src/rtsmart/examples/peripheral/touch
make
```

### Run Mode 1: Test an Existing Device

Run the sample directly to read points from an existing touch device.

### Run Mode 2: Create the Device Dynamically and Test

Use the dynamic-create path when the touch device needs to be created from configuration before reading events.

## Common Parameters

Use the device path and related touch configuration that match your board setup.

## Output Interpretation

The sample prints touch points, event type, and device information so you can confirm whether the touch input path is working correctly.
