2.83" 4DGL-Platform AMOLED Module (with Touch)
This product us RoHS compliant This product is PbFree



The uOLED-32028-P1T(GFX) is a 2.83" size compact and cost effective all in one ‘SMART” display module (with integrated touch screen) using the latest state of the art Active Matrix OLED (AMOLED) technology with an embedded PICASO-GFX2 graphics controller that delivers ‘stand-alone’ functionality to any project.

The PICASO-GFX2 belongs to a family of processors powered by a highly optimised soft core virtual  engine,  E.V.E.  (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.

4DGL allows the developer to write applications in a high level syntax similar to popular languages such as BASIC, C and Pascal and run it directly on the PICASO-GFX2 processor embedded in the uOLED-32028-P1T module. It allows the user to take complete control of all available resources on that hardware platform such as the Serial Ports, Graphics AMOLED Display, uSD memory card, I/O pins, etc. This eliminates the need for an external host controller/processor to drive the uOLED-32028-P1T module via serial commands. It provides the user complete control over the hardware module allowing them to quickly develop powerful applications.


Note: The PICASO processor on the Display module can be re-programmed with the latest PmmC configuration for updates and future proofing (as well as 4DGL program downloads). This process requires the use of a USB converter that uses the DTR signal to pulse the Reset line on the processor, such as any one of the following 4D Programming modules:


Warranty Note: PmmC or 4DGL programming should only be carried out using any one of the 4D Programming modules (4D Programming Cable, uUSB-MB5, uUSB-CE5). Any malfunction because of custom or third party USB to Serial converters or Serial(RS232) to Serial(TTL) level converters will void the warranty.

It also applies to all 4D products which require an interface from the PC to the module for testing using 4D Software Test Tools.

It applies to all the purchases on or after 1st of July 2011.
