Description: The uLCD-32PT(GFX) is a compact and cost effective all in one ‘SMART” display module using the latest state of the art Active Matrix LCD (TFT) technology with an embedded PICASO-GFX2 graphics controller that delivers ‘stand-alone’ functionality to any project.

The PICASO-GFX2 belongs to a family of processors powered by a highly optimised soft core virtual  engine,  E.V.E.  (Extensible Virtual Engine). EVE is a proprietary, high performance virtual processor with an extensive byte-code instruction set optimised to execute compiled 4DGL programs. 4DGL (4D Graphics Language) was specifically developed from ground up for the EVE engine core. It is a high level language which is
easy to learn and simple to understand yet powerful  enough to tackle many embedded graphics applications.

4DGL allows the developer to write applications in a high level syntax similar to popular languages such as BASIC, C and Pascal and run it directly on the PICASO-GFX2 processor embedded in the uLCD-32PT module. It allows the user to take complete control of all available resources on that hardware platform such as the Serial Ports, Graphics LCD Display, uSD memory card, I/O pins, etc. This eliminates the need for an external host controller/processor to drive the uLCD-32PT module via serial commands. It provides the user complete control over the hardware module allowing them to quickly develop powerful applications.

Note: The module can be switched to a "SGC" by changing the firmware. Also, It's been brought to our attention that trying to program the 4D screens using an FTDI breakout can damage the driver. You'll need to use the FT232RQ USB to Serial which you can find in the related items below.
