Description: The μLCD43(GFX) is an intelligent graphics display that harnesses the power of Active Matrix LCD (TFT) technology to deliver a diverse range of features in a single, compact cost effective unit. Embedded at the heart of the design is the PICASO-GFX2 processor.
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 uLCD-43 module. It allows the user to take complete control of all available resources on that hardware platform such as the Serial Ports, Graphics LCD Display, uSD memory card, I/O pins, etc. This eliminates the need for an external host controller/processor to drive the uLCD-43 module via serial commands. It provides the user complete control over the hardware module allowing them to quickly develop powerful applications.
Note: The module can be switched to a "SGC" by changing the firmware.
