µLCD-32PT(GFX)
3.2” Display Module
Data Sheet
Description
The uLCD-32PT(GFX) is a compact and cost
effective all in one ‘SMART” display module using
the latest state of the art LCD (TFT) 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
uLCD-32PT 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-32PT
module via serial commands. It provides the user
complete control over the hardware module
allowing them to quickly develop powerful
applications.
Features
• Low-cost 3.2" LCD-TFT display graphics user
interface solution.
• 240 x 320 QVGA resolution, RGB 65K true to life
colours, TFT screen.
• Integrated 4-Wire resistive Touch Panel.
• Easy 5 pin interface to any host device:
VCC, TX, RX, GND, RESET.
• Powered by the 4D-Labs PICASO-GFX2
processor (also available as separate OEM IC for
volume users).
• 15K bytes of flash memory for user code
storage and 14K bytes of SRAM for user
variables.
• 2 x Asynchronous hardware serial ports (COM0,
COM1), TTL interface, with 300 baud to 256K
baud.
• 1 x I2C interface (Master).
• 8 x 16 bit timers with 1 millisecond resolution.
• 16 x General Purpose I/O pins. Upper 8 bits can
be used as an I/O Bus for fast 8-bit parallel data
transfers.
• On-board micro-SD memory card adaptor for
multimedia storage and data logging purposes.
HC memory card support is also available for
cards larger than 4Gb.
• DOS compatible file access (FAT16 format) as
well as low level access to card memory.
• Dedicated PWM Audio pin supports FAT16
audio WAV files and complex sound generation.
• On-board audio amplifier with a tiny 8 Ohms
speaker for sound generation and WAV file
playback.
• Built in extensive 4DGL graphics and system
library functions. For all available features and
functions under the 4DGL programming
language.
