1 Introduction
The µLCD-32032-P1T is a 3.2” size cost effective all in one ‘SMART’ display
module using the latest state of the art LCD TFT technology with an embedded
PICASO-GFX graphics controller that delivers ‘stand-alone’ functionality to any
project. The ‘easy to learn and use’ 4D Graphics Language (4DGL) with vast built
in library functions will allow rapid application development.
4DGL is a graphics oriented programming language, allowing 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-GFX processor embedded in
the µLCD-32032-P1T module.
4DGL allows the user to take complete control of all available resources on that
hardware platform such as the Serial Port, Graphics AMOLED Display, µSD
memory card, I/O pins, etc. This eliminates the need for an external host
controller/processor to drive the µLCD-32032-P1T module via serial commands. It
provides the user complete control over the hardware module allowing them to
quickly develop powerful applications.

2 Features
The µLCD-32032-P1T module is aimed at being integrated into a variety of
different applications via a wealth of features designed to facilitate any given
functionality quickly and cost effectively and thus reduce ‘time to market’. These
features are as follows:
• 3.2” QVGA 240 x RGB x 320 pixel resolution with 256, 65K or 262K true to
life colours enhanced TFT screen.
• Wide viewing angle.
• Module size including PCB: 55.1 x 77.0 x 14.0mm.
• Display viewing area: 48.6 x 64.8mm
• Easy 5 pin user interface (VCC, TX, RX, GND, RESET) to any 4D micro-USB
module such as the µUSB-MB5 or the µUSB-CE5.
• Voltage supply from 4.5V to 5.5V, current @ 90mA nominal when using a
5.0V supply source.
• Onboard micro-SD (µSD) memory card adaptor with full FAT16 file support
for storing and executing 4DGL programs, files, icons, images, animations,
video clips and audio wave files. 64Mb to 2Gig µSD memory cards can be
purchased separately.
Powered by the fully integrated PICASO-GFX Graphics Processor (PICASO-
GFX chip is also available for OEM volume users).
Built in extensive 4DGL graphics and system library functions. For all available
features and functions under the 4DGL programming language please visit the
4DGL web page http://www.4dsystems.com.au/developers/
2 x 30 pin headers for I/O expansion and future plug-in daughter boards.
Audio amplifier with a tiny 8 Ohms speaker for sound generation and wave file
playback.
Mechanical support via 4 mounting tabs which can be snapped off.

6 USB to Serial Interface - microUSB
The µLCD-32032-P1T module is required to be interfaced to a PC for uploading the
PICASO-GFX chip with user application 4DGL code. Using a standard USB cable
and any one of the 4D Systems micro-USB modules (µUSB-MB5 or µUSB-CE5)
as shown below, a PC to µLCD-32032-P1T connection can be achieved simply.
The micro-USB interface is also used for PmmC (Personality module micro Code)
uploads. The PmmC allows the latest Operating System and 4DVM (4D Virtual
Machine) upgrades for the PICASO-GFX chip. The micro-USB module (optional
extra), simply connects to the µLCD-32032-P1T module and captures the USB
data and converts it into serial CMOS level (0 to 3.3V) data. The micro-USB
modules and drivers are available from your local 4D distributor. This is an
optional extra product and is not included with the module.
