These are referred to as the COM0 and the COM1 serial ports. The primary features are: SPI Interface – Memory Card The Picaso supports SD, micro-SD and MMC memory cards via its hardware SPI interface. The memory card is used for all multimedia file retrieval such as images, animations and movie clips and the SPI interface is dedicated for this purpose only. The memory card can also be used as general purpose storage for data logging applications (RAW and FAT16 format support). Support is available for micro-SD with up to 2GB capacity and for high capacity HC memory cards starting from 4GB and above. • • • • 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. SDI pin (SPI Serial Data In): The SPI Serial Data Input (SDI). SD memory card use only. Connect this pin to the SPI Serial Data Out (SDO) signal of the memory card. SDO pin (SPI Serial Data Out): The SPI Serial Data Output (SDI). SD memory card use only.

Connect this pin to the Chip Enable (CS) signal of the memory card. PICASO DATASHEET Page 9 of 26 www.4dsystems.com.au PICASO GRAPHICS PROCESSOR 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. Audio Interface The exclusive audio support in the Picaso Processor 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: Picaso Internal Functions Manual 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. AUDIO pin (Audio PWM output): External Amplifier Output pin. This pin provides a 16bit DAC/PWM audio output to use with an external audio amplifier. Example circuit below provides a low cost implementation. If unused then this pin must be left open or floating. Refer to Section 7.

PICASO DATASHEET Page 10 of 26 www.4dsystems.com.au PICASO GRAPHICS PROCESSOR Touch Screen Interface GPIO – General Purpose IO The Picaso supports 4-Wire resistive touch panels. The diagram below shows a simplified interface between the Picaso and a touch panel. 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 Internal Functions Manual IO1-IO3 pins (3 x GPIO pins): General purpose I/O pins. Each pin can be individually set for INPUT or an OUTPUT. Power-Up Reset default is all INPUTS. XR pin (Touch Panel X-Read input): 4-Wire Resistive Touch Screen X-Read analog signal. Connect this pin to XR or X+ signal of the touch panel. 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. XL pin (Touch Panel X-Drive output): 4-Wire Resistive Touch Screen X Drive signal. Connect this pin to XL or X- signal of the touch panel. 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. YU pin (Touch Panel Y-Read input): 4-Wire Resistive Touch Screen Y-Read analog signal. Connect this pin to YU or Y+ signal of the touch panel. BUS0-BUS7 pins (GPIO 8-Bit Bus): 8-bit parallel General purpose I/O Bus. YD pin (Touch Panel Y-Drive output): 4-Wire Resistive Touch Screen Y Drive signal. Connect this pin to YD or Y- signal of the touch panel. PICASO DATASHEET Note: All GPIO pins are 5.0V tolerant. Page 11 of 26 www.4dsystems.com.au PICASO GRAPHICS PROCESSOR System Pins 6. 4DGL – Software Language VCC pins (Device Supply Voltage): Device supply voltage pins. These pins must be connected to a regulated supply voltage in the range of 3.0 Volts to 3.6 Volts DC. Nominal operating voltage is 3.3 Volts. GND pins (Device Ground): Device ground pins. These pins must be connected to system ground. RESET pin (Device Master Reset): Device Master Reset pin. An active low pulse of greater than 2 micro-seconds will reset the device. Connect a resistor (1K through to 10K, nominal 4.7K) from this pin to VCC. Only use open collector type circuits to reset the device if an external reset is required. This pin is not driven low by any internal conditions. CLK1, CLK2 pins (Device Oscillator Inputs): CLK1 and CLK2 are the device oscillator pins. Connect a 12MHz AT strip cut crystal with 22pF capacitors from each pin to GND as shown in the diagram below. The Picaso processor belongs to a family of processors powered by a highly optimised soft core virtual engine, EVE (Extensible Virtual Engine). EVE is a proprietary, high performance virtualmachine 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 is a graphics oriented language allowing rapid application development, and the syntax structure was designed using elements of popular languages such as C, Basic, Pascal and others. Programmers familiar with these languages will feel right at home with 4DGL. It includes many familiar instructions such as IF..ELSE..ENDIF, WHILE..WEND, REPEAT..UNTIL, GOSUB..ENDSUB, GOTO, PRINT as well as some specialised instructions SERIN, SEROUT, GFX_LINE, GFX_CIRCLE and many more. For detailed information pertaining to the 4DGL language, please refer to the following documents: 4DGL Programmer's Reference Manual Picaso Internal Functions Manual To assist with the development of 4DGL applications, the Workshop4 IDE combines a full-featured editor, a compiler, a linker and a downloader into a single PCbased application. It's all you need to code, test and run your applications. PICASO DATASHEET Page 12 of 26 www.4dsystems.com.au PICASO GRAPHICS PROCESSOR 7. In Circuit Serial Programming 8. Picaso Architecture The Picaso processor is a custom graphics processor. All functionality including the high level commands are built into the chip. This chip level configuration is available as a Firmware/PmmC (Personality-modulemicro-Code) file. The figure below illustrates the Picaso Processors architecture. A PmmC file contains all of the low level micro-code 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 and an access to this must be provided for on the target application board. This is referred to as In Circuit Serial Programming (ICSP). Figure below provides a typical implementation for the ICSP interface. Picaso is a high level graphics processor which runs the high level 4DGL (4D Graphics Language). It is not a conventional microcontroller with conventional microcontroller architecture, it is a custom graphics processor and therefore low level access to the chip is not required nor available to the User. The PmmC file is programmed into the device with the aid of Workshop4, the 4D Labs IDE software (See Section 12). To provide a link between the PC and the ICSP interface, a specific 4D Programming Cable is required and is available from 4D Systems. 4DGL provides high level functions for the User and does all the low level work in the background in a highly optimised fashion. Using a non-4D programming interface could damage your processor, and void your Warranty. Note: The Picaso processor is shipped blank and it must be programmed with the PmmC configuration file. PICASO DATASHEET Page 13 of 26 www.4dsystems.com.au PICASO GRAPHICS PROCESSOR PmmC Firmware PmmC (Personality Module Micro-Code) - this is the operating system, incorporating the EVE runtime (Extensible Virtual Engine) which has an extensive byte-code instruction set programmed via the Workshop4 Software IDE. The PmmC Loader can be thought of like a bootloader, and allows the transfer of a PmmC from the Users’ PC into the System Flash storage on the Picaso processor. Within the PmmC are hundreds of built in functions for graphics, sound, math functions etc, no need to include libraries, or wait for hefty compile times – it’s all built in. The PmmC is in protected memory, and cannot be read or damaged by inadvertent writes to illegal FLASH areas. The PmmC is upgradable by the User and can be done at any time. It however will wipe the Users application from Flash, so this will need to be reloaded after a PmmC update is completed. Loading the PmmC is achieved using our PmmC Loader tool, or using the ScriptC command line tool. Note: IMPORTANT!!! If you are wanting to use Picaso in a product, please contact the 4D Labs Tech Support or Sales departments to discuss your requirements. PmmC’s can ONLY be created by 4D Labs, and depending on the display you have selected and the Driver IC it uses, will determine how difficult the process is.

Hardware Tools The Picaso Processor uses off the shelf standard SDHC/SD/micro-SD 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 based application. The following hardware tools are required for full control of the Picaso Processor. The Picaso Processor 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. Programming Tools The 4D Programming Cable and 4D-UPA Programming Adaptor are essential hardware tools to program, customise and test the Picaso Processor. Anyone of these can be used. The 4D programming interfaces are used to program a new Firmware/PmmC, Display Driver and for downloading compiled 4DGL code into the processor. They even serve as an interface for communicating serial data to the PC. The 4D Programming Cable and 4D-UPA Programming Adaptor are available from 4D Systems, www.4dsystems.com.au Using a non-4D programming interface could damage your processor, and void your Warranty. The FAT partition is always first (if it exists) and can be up to the maximum size permitted by FAT16. Windows 7 will format FAT16 up to 4GB. Windows XP will format FAT16 up to 2GB and the Windows XP command prompt will format FAT16 up to 4GB. RMPET, a 4D Labs Tool found in the Workshop4 IDE, is capable of repartitioning and formatting microSD cards to be the appropriate type and format for 4D Labs processors. This should be used for all cards. 4D Programming Cable Note: A SPI Compatible SDHC/SD/micro-SD card MUST be used. Picaso along with other 4D Labs Processors require SPI mode to communicate with the SD card. If a non-SPI compatible SD card is used then the processor will simply not be able to mount the card. 4D-UPA Programming Adaptor PICASO DATASHEET Page 17 of 26 www.4dsystems.com.au PICASO GRAPHICS PROCESSOR Evaluation Display Modules The following modules, available from 4D Systems, can be used for evaluation purposes to discover what the Picaso processor has to offer. gen4-uLCD-24PT – 2.4” Intelligent Picaso Display gen4-uLCD-28PT – 2.8” Intelligent Picaso Display gen4-uLCD-32PT – 3.2” Intelligent Picaso Display Note: gen4 Picaso display module plastic ships in Red colour, not white as pictured. PICASO DATASHEET Page 18 of 26 www.4dsystems.com.au PICASO GRAPHICS PROCESSOR Designer Environment 12. 4D Labs - Workshop4 IDE Workshop4 is a comprehensive software IDE that provides an integrated software development platform for all of the 4D family of processors and modules. The IDE combines the Editor, Compiler, Linker and Down- Loader to develop complete 4DGL application code. All user application code is developed within the Workshop4 IDE. The Workshop4 IDE supports multiple development environments for the user, 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 Picaso 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, set the events to drive them and the code is written for you automatically. ViSi-Genie provides the latest rapid development experience from 4D Labs. • A Serial environment is also provided to transform the Picaso module into a slave serial module, allowing the user to control the display from any host microcontroller or device with a serial port. Choose the Designer environment to write 4DGL code in its raw form. The Designer environment provides the user with a simple yet effective programming environment where pure 4DGL code can be written, compiled and downloaded to the Picaso. ViSi Environment ViSi was designed to make the creation of graphical displays a more visual experience. ViSi is a great software tool that allows the user to see the instant results of their desired graphical layout. Additionally, there is a selection of inbuilt dials, gauges and meters that can simply be placed onto the simulated module display. From here each object can have its properties edited, and at the click of a button all relevant 4DGL code associated with that object is produced in the user program. The user can then write 4DGL code around these objects to utilise them in the way they choose. The Workshop4 IDE is available from the 4D Labs website. www.4dsystems.com.au For a comprehensive manual on the Workshop4 IDE Software along with other documents, refer to the documentation from the 4D Labs website, on the Workshop4 product page. PICASO DATASHEET Page 19 of 26 www.4dsystems.com.au PICASO GRAPHICS PROCESSOR ViSi Genie Environment Serial Environment ViSi Genie is a breakthrough in the way 4D Labs’ graphic modules are programmed. It is an environment like no other, a code-less programming environment that provides the user with a rapid visual experience, enabling a simple GUI application to be ‘written’ from scratch in literally seconds. ViSi Genie does all the background coding, no 4DGL to learn, it does it all for you. Pick and choose the relevant objects to place on the display, much like the ViSi Environment, yet without having to write a single line of code. Each object has parameters which can be set, and configurable events to animate and drive other objects or communicate with external devices. Simply place an object on the screen, position and size it to suit, set the parameters such as colour, range, text, and finally select the event you wish the object to be associated with, it is that simple. The Serial environment in the Workshop4 IDE provides the user the ability to transform the Picaso into a slave serial graphics controller. This enables the user to use their favourite microcontroller or serial device as the Host, without having to learn 4DGL or program in a separate IDE. Once the Picaso is configured and downloaded to from the Serial Environment, simple graphic commands can be sent from the users host microcontroller to display primitives, images, sound or even video. Refer to the Picaso Serial Command Set Reference Manual from the Workshop4 product page on the 4D Systems website for a complete listing of all the supported serial commands. In seconds you can transform a blank display into a fully animated GUI with moving sliders, animated press and release buttons, and much more. All without writing a single line of code! ViSi Genie provides the user with a feature rich rapid development environment, second to none. PICASO DATASHEET Page 20 of 26 www.4dsystems.com.au DIABLO16 GRAPHICS PROCESSOR 13.
