Serial TFT LCD 4.3" with Touchscreen - uLCD43

 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. It’s been brought to our attention that trying to program the 4D screens using an FTDI breakout can damage the driver. Check theRecommended Items section below for 4D Systems' µUSB-PA5.
