PICASO OGM Base Board

8.2.

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.

Please refer to the datasheet for the BaseBoard,

available from the PICASO OGM Product Page.

9. 4DGL - Software Language

The PICASO OGM Module utilises the PICASO

processor, which belongs to a family of processors

engine, EVE (Extensible Virtual Engine).

EVE is a proprietary, high performance virtual-

machine with an extensive byte-code instruction

set

optimised

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”

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.
