1. Description

The PICASO Processor is a custom embedded 4DGL

graphics controller designed to interface with

many popular OLED and LCD display panels.

Powerful graphics, text, image, animation and

countless more features are built right inside the

chip. It offers a simple plug-n-play interface to

many 16-bit 80-Series colour LCD and OLED

displays.

The chip is designed to work with minimal design

effort and all of the data and control signals are

provided by the chip to interface directly to the

display. Simply choose your display and interface it

to the PICASO on your application board. This

offers enormous advantage to the designer in

development time and cost saving and takes away

all of the burden of low level design.

The PICASO belongs to a family of processors

engine, EVE (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.

The device offers modest but comprehensive I/O

features and can interface to I2C, serial, digital,

buttons, joystick and many more. Provision is also

made for a dedicated PWM audio output that

supports audio WAV files and complex sound

generation.

All of the display built-in driver libraries implement

and share the same high-level function interface.

This allows your GUI application to be portable to

different display controller types.

4D Systems software development IDE called

Workshop 4 is FREE and there are no licensing

requirements.

The PICASO Processor offers one of the most

flexible embedded graphics solutions available.
