8.2. PICASO OGM Base Board
4D Systems has designed a BaseBoard for the
OGM Module, which provides an evaluation type
interface for the OGM Module, to enable it to be
easily powered up, programmed and tested.
This evaluation board is called the OGM
BaseBoard, and is available from the 4D Systems.
Please discuss with the 4D Systems Sales team if a
BaseBoard would assist with your development.
The PICASO OGM Module is required to be
soldered into place on the OGM BaseBoard.

9. 4DGL - Software Language
The PICASO OGM Module 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.
Please refer to the datasheet for the BaseBoard,
available from the PICASO OGM Product Page.
