Usage

<lcd:LcdLabel Text="Default" />

We're defining a basic default LCD label, nothing fancy.

Predefined Color Themes

<lcd:LcdLabel Text="Default Purple" 
              NumberOfCharactersPerLine="14" 
              ColorScheme="Green"/>

Here we define a few of the available properties, We're increasing the number of characters from 10 (the default) to 14 and we have also specified the Purple color scheme.

Multi Line

<lcd:LcdLabel Text="Multi-line" NumberOfTextLines="2" NumberOfCharactersPerLine="5" />

Here we have configured the LCD control to have two lines of text, each with 5 characters.

Alternate Sizes

<lcd:LcdLabel Text="{Binding Greeting}"
              DotMatrix="Dos5X7"
              NumberOfCharactersPerLine="24"
              LineSpacing="10"
              BorderSpace="10"
              PixelSize="Pix4X4" />

Here we have a large LCD display.

• Text is data-bound to the view models Greeting property
• DotMatrix is set to Dos5X7 (default Mat5X7)
• NumberOfCharactersPerLine is set to 24 (default 10)
• LineSpacing is set to 10 (default 2)
• BorderSpace is set to 10 (default 3)
• PixelSize is set to Pix4X4 (default Pix2X2)

Custom Pixel Size

<lcd:LcdLabel Text="Custom Pixels" NumberOfCharactersPerLine="13" PixelSize="PixCustom" PixelHeight="2" PixelWidth="8" />

Animations

You can animate the LCD contents by setting the IsAnimated property to True and using the animation properties to control various aspects of the animation behaviour.

<lcd:LcdLabel Text="{Binding Greeting}"
              NumberOfCharactersPerLine="24"
              ColorScheme="Green"
              IsAnimated="True"
              AnimationSpeed="10"
              AnimationStyle="Loop"/>

The AnimationSpeed property controls the speed in FPS. The value used here is divided by 1000. The AnimationStyle property controls the overall behaviour of the animation. The two options are Loop and Contiguous. Looped content will cycle to completion whereas Contiguous content cycles the string in a continuous stream of characters.
