7. Hardware Tools
The following hardware tools are required for full
control of the μVGA-III module.
7.1.
The 4D Programming Cable is an essential
hardware tool to program, customise and test the
μVGA-III module.
The 4D Programming Cable is used to program a
new Firmware/PmmC and downloading compiled
4DGL code into the module. It even serves as an
interface for communicating serial data to the PC.
The 4D Programming Cable is available from 4D

8. 4DGL - Software Language
The μVGA-III 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
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
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.
