====== GHB3224C ======

The GHLCD is an LCD that features the ability to display characters and
graphics on three different layers. Unlike the CLCD, the GHLCD supports
many different commands for easily drawing lines, circles, and boxes.
There are also commands to copy, cut, and paste graphics, and a BMP
downloader for downloading images to the GHLCD.

print outside the specified range of pixels shown here.

==== GHB3224C supports I2C(CuNET) =====

The GHB3224C model supports CuNET. When using Cubloc with the
GHCLD, using CuNET instead of serial communications will free up the serial
port for other uses.

GHB3224C CuNET settings:

<code xbasic>
Set Display 1,0,1,50     ' GHLCD, CUNET, Set Address to 1. Send buffer to 50.
</code>

*Warning : The CuNET slave address and display slave address must match.
The display lave address can be set with the DIP switch.

==== GHB3224C DIP Switch Settings ====

On the back of the GHB3224C, there are DIP switches to set the RS232
baud rate and I2C slave address. GHB3224C DIP Switch number 4 is not
used.
