microLCD 2.8" PICASO Display Module with Resistive Touch
**The µLCD-28PTU is recommended for new designs, and superseeds the old µLCD-28PT display module***
The µLCD-28PTU is a compact and cost effective Intelligent Display Module packed with plenty of features, ready to become the GUI for your target application, and capable of being an interface controller for a number of applications.
Embedded at the heart of the design is the PICASO processor, which is driven by a highly optimised virtual core engine called EVE (Extensible Virtual Engine). An extensive range of hardware and software peripherals have been integrated into the design, to give the user freedom to adapt the module to suit almost any application.
The µLCD-28PTU is an elegant combination of a 2.8” (240x320) LCD Screen, audio amplifier and speaker, micro-SD card connector, Lithium Polymer (LiPo) battery support, along with a group of general purpose input/output pins (GPIO's), including I2C and serial COMMS.
The µLCD-28PTU display module serves as a perfect solution to be deployed at the forefront of any product design, requiring a brilliance of colour, animation or images on any application. This PICASO driven Intelligent Display Module is a perfect example of where art meets technology.
The PmmC for this product for use with Workshop 4 is available from the Workshop 4 Product Page, on the PmmC/Firmware tab.
Please download this Product Brief and Datasheet for the µLCD-28PTU display module:
Note: The PICASO processor on the Display module can be re-programmed with the latest PmmC/Firmware for updates and future proofing via the Workshop 4 IDE Software. This process requires the use of the 4D Programming cable:

4D Systems all new Workshop 4 IDE supports multiple development environments, to cater for different user requirements and skill level.
The Designer environment enables the user to write 4DGL code in its natural form to program the display module.
A visual programming experience, suitably called ViSi, enables drag-and-drop type placement of objects to assist with 4DGL code generation and allows the user to visualise how the display will look while being developed.
An advanced environment called ViSi-Genie doesn’t require any 4DGL coding at all, it is all done automatically for you. Simply lay the display out with the objects you want (similar to ViSi), set the events to drive them and the code is written for you automatically. ViSi-Genie provides the latest rapid development experience from 4D Systems.
A Serial environment is also provided to transform the display module into a slave serial display module, allowing the user to control the display from any host microcontroller or device with a serial port.
The Workshop 4 IDE is available for download from its product page: 4D Workshop 4 IDE
With each uLCD-28PTU Display Module, you also receive the following:
150mm 5 way Female-Female jumper cable, for quick connection to another device or breadboard
5 way Male-Male adaptor (for converting the Female-Female cable to be Male-Female)

Other things you may like to purchase seperately are:
Warranty Note: PmmC/Firmware or user application code programming should only be carried out using the 4D Programming cable (4D Programming Cable). 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.
