Why Haidar Technology?
There are a number of produts on the market that offer graphics primitives over a serial port. This is an acceptable choice for text and non-interactive graphics, but a very poor choice for a GUI. A GUI requires much more than just the ability to draw geometric shapes and text! Displayed objects must accommodate behaviors linked to the real-time user interface. This will put much of the GUI software complexity on the side of the host processor, which greatly increases the serial interface bandwidth between the two processors.
