* 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. 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. * 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.

LCD-32PT(GFX) 2. Hardware Interface - Pins
The ULCD-32PT(GFX) provides both a hardware and a software interface. This section describes in detail the hardware interface pins of the device.
Data Sheet
2.1 Serial Ports - COM0, COM1 UARTS
The PICASO-GFX2 has two dedicated hardware Asynchronous Serial ports that can communicate with external serial devices. These are referred to as the COM0 and the COM1 serial ports. The primary features are: * Full-Duplex 8 bit data transmission and reception. * * * Data format: 8 bits, No Parity, 1 Stop bit. Independent Baud rates from 300 baud up to 256K baud. Single byte transmits and receives or a fully buffered service. The buffered service feature runs in the background capturing and buffering serial data without the user application having to constantly poll any of the serial ports. This frees up the application to service other tasks. COM0 is also the primary interface for 4DGL user program downloads and chip configuration PmmC programming. Once the compiled 4DGL application program (EVE byte-code) is downloaded and the user code starts executing, the serial port is then available to the user application. Refer to Section 5. In-Circuit-SerialProgramming (ICSP) for more details on PmmC programming. TX0 pin (Serial Transmit COM0): Asynchronous Serial port COM0 transmit pin, TX0. Connect this pin to external serial device receive (Rx) signal. This pin is 5.0V tolerant. RX0 pin (Serial Receive COM0): Asynchronous Serial port COM0 receive pin, RX0. Connect this pin to external serial device transmit (Tx) signal. This pin is 5.0V tolerant. TX1 pin (Serial Transmit COM1): Asynchronous Serial port COM1 transmit pin, TX1. Connect this pin to external serial device receive (Rx) signal. This pin is 5.0V tolerant. RX1 pin (Serial Receive COM1): Asynchronous Serial port COM1 receive pin, RX1. Connect this pin to external serial device transmit (Tx) signal. This pin is 5.0V tolerant.
A single byte serial transmission consists of the start bit, 8-bits of data followed by the stop bit. The start bit is always 0, while a stop bit is always 1. The LSB (Least Significant Bit, Bit 0) is sent out first following the start bit. Figure below shows a single byte transmission timing diagram.

LCD-32PT(GFX) 2.2 GPIO - General Purpose IO Interface
There are 13 general purpose Input/Output (GPIO) pins available to the user. These are grouped as IO1..IO5 and BUS0..BUS7. The 5 I/O pins (IO1..IO5), provide flexibility of individual bit operations while the 8 pins (BUS0..BUS7), known as GPIO BUS, serve collectively for byte wise operations. The IO4 and IO5 also act as strobing signals to control the GPIO Bus. GPIO Bus can be read or written by strobing a low pulse (50 nsec duration or greater) the IO4/BUS_RD or IO5/BUS_WR for read or write respectively. For detailed usage refer to the separate document titled: 'PICASO-GFX2-4DGL-Internal-Functions.pdf'. IO1-IO3 pins (3 x GPIO pins): General purpose I/O pins. Each pin can be individually set for INPUT or an OUTPUT. PowerUp Reset default is all INPUTS. IO4/BUS_RD pin (GPIO IO4 or BUS_RD pin): General Purpose IO4 pin. Also used for BUS_RD signal to read and latch the data in to the parallel GPIO BUS0..BUS7. IO5/BUS_WR pin (GPIO IO5 or BUS_WR pin): General Purpose IO5 pin. Also used for BUS_WR signal to write and latch the data to the parallel GPIO BUS0..BUS7. BUS0-BUS7 pins (GPIO 8-Bit Bus): 8-bit parallel General purpose I/O Bus. Note: All GPIO pins are 5.0V tolerant.

LCD-32PT(GFX) 4. PmmC Programming
The PICASO-GFX2, used in the ULCD-32PT(GFX) module, is a custom graphics controller. All functionality including the high level commands are built into the chip. This chip level configuration is available as a PmmC (Personalitymodule-micro-Code) file. A PmmC file contains all of the low level microcode information (analogy of that of a soft silicon) which define the characteristics and functionality of the device. The ability of programming the device with a PmmC file provides an extremely flexible method of customising as well as upgrading it with future enhancements. A PmmC file can only be programmed into the device via its COM0 serial port Figure below provides a typical implementation for the PmmC programming interface.
Data Sheet 5. Module Features
The ULCD-32PT(GFX) module is equipped to accommodate most applications. Some of the main features of the module are listed below.
5.1 The Display - 3.2" TFT
The ULCD-32PT(GFX) module is equipped with a 3.2" TFT display. Details of the display is listed below: * * * * * * * * Screen Size: 3.2" diagonal Screen Dimensions: 56 x 77.6 x 3.7mm Viewing Area: 48.6mm x 64.8mm Integrated Touch Screen Brightness: 300 cd/m2 Contrast Ratio: 250:1 Viewing Angle: 45 degrees 5 x Parallel LEDs for Backlighting
The PmmC file is programmed into the device with the aid of "PmmC Loader", a PC based software tool. To provide a link between the PC and the ICSP interface a USB to Serial converter is required. A range of custom made micro-USB devices such as the uUSB-MB5 and the uUSB-CE5 are available from 4D Systems. For further details refer to: 'Section 8: Development and Support Tools'.

LCD-32PT(GFX) 5.2 The PICASO-GFX2 Processor
The module is designed around the PICASO-GFX2 Graphics Controller from 4D-Labs. The PICASO-GFX2 is a smart Controller and the interface to the TFT- LCD displays is almost plug-nplay. All of the data and control signals are provided by the chip to interface directly to the display. Powerful graphics, text, image, animation and countless more features are built right inside the chip. It offers a simple yet effective serial interface to any external micro-controller that can communicate via a serial port.
Data Sheet 5.4 The Audio
The exclusive audio support in the PICASO-GFX2 makes it better than its peers in the Graphics processor range. PWM ensures better sound quality with a volume range of 8 to 127. A simple instruction empowers the user to execute the audio files. Audio operation can be carried out simultaneously with the execution of other necessary instructions. For a complete list of audio commands please refer to the separate document titled 'PICASOGFX2-4DGL-Internal-Functions.pdf'.. Note: The on-board speaker is a small surface mount device and is designed to project into an audio cavity. It is not very loud by itself..
5.5 The Touch Screen
The module supports an integrated 4-Wire resistive touch panel.
The data sheet for the chip is available from the www.4dsystems.com.au website: "PICASO-GFX2-DS-revx.pdf"
5.3 The uSD Memory Card
The module supports micro-SD memory cards via the on-board uSD connector. The memory card is used for all multimedia file retrieval such as images, animations and movie clips. The memory card can also be used as general purpose storage for data logging applications. Support is available for off the shelf micro-SD and high capacity HC memory cards (4Gb and above). Note: The module also supports FAT file formats.

LCD-32PT(GFX) 6. Memory Cards - FAT16 Format
The PICASO-GFX2 uses off the shelf standard SDHC/SD/microSD memory cards with up to 2Gb capacity usable with FAT16 formatting. For any FAT file related operations, before the memory card can be used it must first be formatted with FAT16 option. The formatting of the card can be done on any PC system with a card reader. Select the appropriate drive and choose the FAT16 (or just FAT in some systems) option when formatting. The card is now ready to be used in the PICASO-GFX2 based application. The PICASO-GFX2 also supports high capacity HC memory cards (4Gb and above). The available capacity of SD-HC cards varies according to the way the card is partitioned and the commands used to access it. The FAT partition is always first (if it exists) and can be up to the maximum size permitted by FAT16. Windows will format FAT16 up to 2Gb and the Windows command prompt will format FAT16 up to 4Gb. For the RAW partition, byte reads and writes can access 2^32 (i.e. 4gb) of the card, Sector reads and writes can access 2^24 sectors (of 512 bytes, i.e. 8gb). The total amount of the card usable is the sum of the FAT and RAW partitions.
Data Sheet 7. Display Precautions
* Avoid having to display the same image/object on the screen for lengthy periods of time. This will cause a burn-in which is a common problem with all types of display technologies. Blank the screen after a while or dim it very low by adjusting the contrast. Better still; implement a screen saver feature. Moisture and water can damage the display. Moisture on the surface of a powered display will cause the electrodes to corrode. Wipe off any moisture gently or let the display dry before usage. Dirt from fingerprint oil and fat can easily stain the surface of the display. Gently wipe off any stains with a soft lint-free cloth. The performance of the display will degrade under high temperature and humidity. Avoid such conditions when storing. Do not tamper with the display flex cable that is connected to the control board. This may effect the connection between the display and the driving circuitry and cause failure. Displays are susceptible to mechanical shock and any force exerted on the module may result in deformed zebra strips, a cracked display cell and broken backlight Always use the mounting holes on the module's printed circuit board to mount the display.

LCD-32PT(GFX) 8.5 RMPET - Software Tool
uSD/SD/SDHC memory cards nearly always come pre-partitioned with a single partition. Windows only accesses the first partition on the card and ignores any other partitions. Removable Media Partition Edit Tool (RMPET) can split a large card into two partitions, the first partition for use as a FAT16 partition and the second partition for use as a RAW partition. RMPET allows setting of the first partition to a percentage of the card, the 2Gb maximum of the FAT16 Windows format program, or the 4Gb maximum of FAT16 when the command prompt format command is used.
