The Graphic LCD Phidgets allows you to display simple images and text. This Phidget connects to your computer through a VINT Hub.
This Phidget is a smart device that must be controlled by a VINT Hub. For more information about VINT, have a look at the VINT Primer. You can use a Phidget Cable to simply and easily connect the two devices. Here's a list of all of the different VINT Hubs currently available:

Use a Phidget cable to connect this device to the hub. You can solder multiple cables together in order to make even longer Phidget cables, but you should be aware of the effects of having long wires in your system.
The Graphic LCD Phidget allows you to display simple images and text. The screen is 128 pixels wide and 64 pixels tall, and each pixel is 0.45 mm. The backlight brightness and pixel contrast can both be controlled from software. You can use default fonts or load your own. The frame buffer allows you to save fonts and images.
You can use your Control Panel to explore your Phidget's channels.
1. Open your Control Panel, and you will find the following channel:
2. Double click on the channel to open the example program. This channel belongs to the LCD channel class:
In your Control Panel, double click on "Graphic LCD Phidget":
1. Setting up your Programming Environment
Before you open a Phidget channel in your program, you can set these properties to specify which channel to open. You can find this information through the Control Panel.
1. Open the Control Panel and double-click on the red map pin icon:
2. The Addressing Information window will open. Here you will find all the information you need to address your Phidget in your program.
See the Phidget22 API for your language to determine exact syntax for each property.
Bitmaps define images to be drawn on the screen of the Graphic LCD display. Bitmaps on the Graphic LCD display are made up of pixels arranged in a grid with a size defined when the bitmap is drawn. You can create a bitmap by defining a byte array of ones and zeroes. Ones are colored in, and zeroes are empty. If you put a line break after each row, it'll be easy to edit the bitmap. In C#, this may look something like this:
Byte[] heart = [0,0,0,0,0,
0,1,0,1,0,
1,1,1,1,1,
1,1,1,1,1,
0,1,1,1,0,
0,0,1,0,0,
0,0,0,0,0,
0,0,0,0,0];
gLCD.WriteBitmap(0, 0, 5, 8, heart);
Custom characters are images associated with given unicode characters. A custom character can be any arrangement of pixels within the space allotted for a single character. Single characters are made up of pixels arranged in a grid with a size defined by setFontSize().
As with regular bitmaps for the Graphic LCD display, you can create a character bitmap by defining a byte array of ones and zeroes. Ones are colored in, and zeroes are empty. If you put a line break after each row, it will be easy to edit the bitmap.
In C#, this may look something like this:
Byte[] heart = [0,0,0,0,0,
0,1,0,1,0,
1,1,1,1,1,
1,1,1,1,1,
0,1,1,1,0,
0,0,1,0,0,
0,0,0,0,0,
0,0,0,0,0];
gLCD.SetFontSize(LCDFont.User2, 5, 8);
gLCD.SetCharacterBitmap(LCDFont.User2,"\x6",heart);
Once stored, characters can be recalled into a text string by using the unicode value for the location (in this example, "\x6"). For example, in C#:
gLCD.WriteText(LCDFont.Dimensions_5x8, 0, 0,"I \x6 Phidgets!");
Custom characters on the LCD1100 are stored as images on the frame buffer. FONT_User1 is stored on frame buffer 1 and FONT_User2 is on frame buffer 2.
These characters occupy the same space as drawings on the framebuffer, and will be displayed onscreen if the framebuffer is flushed. The characters can also be overwritten by using drawing functions on the framebuffer, so it is recommended to only use a given framebuffer either for drawing or storing fonts, but not both.
We recommend using FONT_User2 (frame buffer 2) to store custom fonts, as it can be saved for later use.
In order to use the custom fonts, you must first define their size with setFontSize(). Once the font size is set, custom characters will be placed on the font's frame buffer at a location corresponding to the character number provided.
Characters for each font are stored in rows ordered left-to-right, top-to-bottom. Rows are filled with as many characters as will completely fit across the width of the screen. There are as many rows as will fit on the screen vertically.
On a screen 128 pixels wide by 64 pixels high, if your font is 10 pixels wide by 20 high, you will have 3 rows of 12 characters. This allows for a maximum of 36 characters of that size.
To quickly determine how many characters can be in your custom font, you can call getMaxCharacters() in your code.
Custom character indexing starts with character 0x01 and can be any character between 0x01 and the maximum number of characters that fit on screen.
To determine if an ascii character can be used in a given custom font, you can look at its corresponding ascii value on an ascii table to determine if it is within the limit determined above.
