# go-dcled

Go library for interacting with Dream Cheeky Message Board

![](examples/canvas/result.gif)

## Usage

You can load images (best: 21x7px like ![](dc-logo.png) or ![](go-logo.png)) and display them on the LED message board. Any pixel (R: 255 G: 0 B: 0) will cause a LED to be *on*.

```go

package main

import (

	"fmt"

	"image/png"

	"os"

	"time"

	"github.com/karalabe/hid"

	"github.com/redtoad/go-dcled"

)

func main() {

	var list = hid.Enumerate(0x1D34, 0x0013)

	var device, err = list[0].Open() // Use first device

	if err != nil {

		panic(err)

	}

	println(fmt.Sprintf("Connected to %s %s", device.Manufacturer, device.Product))

	// load image from file

	f, err := os.Open("go-logo.png")

	if err != nil {

		panic(err)

	}

	defer f.Close()

	img, err := png.Decode(f)

	if err != nil {

		panic(err)

	}

	// display image on device

	for {

		dcled.DisplayCanvas(img, device)

		time.Sleep(dcled.MinimumRefreshRate)

	}

}

```
