8. Hardware Tools
The following hardware tools are required for full
control of the µLCD-43 module.
4D Programming Cable/Adaptor
The 4D Programming Cable and uUSB-PA5
Programming Adaptor are essential hardware tools
to program, customise and test the PICASO
Processor.
Either the 4D Programming Cable or the uUSB-PA5
Programming Adaptor can be used.
The 4D programming interfaces are used to
program a new Firmware/PmmC and for
downloading compiled 4DGL code into the
processor. They even serve as an interface for
communicating serial data to the PC.
The 4D Programming Cable and uUSB-PA5
Programming Adaptor are available from 4D
Systems,
Using a non-4D programming interface could
damage your processor, and void your Warranty.

9. 4DGL - Software Language
The µLCD-43 utilises the PICASO processor, which
belongs to a family of processors powered by a
highly optimised soft core virtual engine, EVE
(Extensible Virtual Engine).
EVE is a proprietary, high performance virtual-
machine 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 is a graphics oriented language allowing rapid
application development, and the syntax structure
was designed using elements of popular languages
such as C, Basic, Pascal and others.
Programmers familiar with these languages will feel
right at home with 4DGL. It includes many familiar
instructions such as IF..ELSE..ENDIF, WHILE..WEND,
REPEAT..UNTIL, GOSUB..ENDSUB, GOTO, PRINT as
well as some specialised instructions SERIN,
SEROUT, GFX_LINE, GFX_CIRCLE and many more.
For detailed information pertaining to the 4DGL
language, please refer to the following documents:
“4DGL-Programmers-Reference-Manual.pdf”
“PICASO-4DGL-Internal-Functions.pdf”
To assist with the development of 4DGL
applications, the Workshop 4 IDE combines a full-
featured editor, a compiler, a linker and a down-
loader into a single PC-based application. It's all you
need to code, test and run your applications.
4DGL is available to be written in two of the four
environments offered by the Workshop 4 IDE,
Designer and ViSi.
