4D SYSTEMS µLCD-43 4. Hardware Interface - Pins The µLCD-43 provides both a hardware and software interface. This section describes in detail the hardware interface pins of the device. Serial Ports - COM0, COM1 UARTS The µLCD-43 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.
4D SYSTEMS µLCD-43 System Pins +5V (Module Voltage Input) J1 pin 12, J2 pins 1/2: Module supply voltage input pin. This pin must be connected to a regulated supply voltage in the range of 4.5 Volts to 5.5 Volts DC. Nominal operating voltage is 5.0 Volts. 3.3V Out (3.3V Regulated Output) J1 pin 20: External circuitry that requires a regulated 3.3V supply can be powered up via this pin. Maximum available current is 150mA.
4D SYSTEMS µLCD-43 5. PmmC/Firmware Programming The PICASO processor used in the µLCD-43 module 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-module-micro-Code) file. 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.
4D SYSTEMS µLCD-43 6. Module Features The µLCD-43 module is designed to accommodate most applications. Some of the main features of the module are listed below. 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. The data sheet for the processor is available from the http://www.4dsystems.com.au website: “PICASO-Processor-Datasheet-REVx.pdf” Display – 4.
4D SYSTEMS µLCD-43 will simply fail to mount, or may cause intermittent issues resulting in lock ups and crashing of the application. Please refer to the 4D Systems website for microSD cards offered by 4D Systems. FAT16 The µLCD-43 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.
4D SYSTEMS µLCD-43 8. Hardware Tools 9. 4DGL - Software Language The following hardware tools are required for full control of the µLCD-43 module. The µLCD-43 utilises the PICASO processor, which belongs to a family of processors powered by a highly optimised soft core virtual engine, EVE (Extensible Virtual Engine). 4D Programming Cable/Adaptor The 4D Programming Cable and uUSB-PA5 Programming Adaptor are essential hardware tools to program, customise and test the PICASO Processor.
4D SYSTEMS µLCD-43 Workshop 4 – Designer Environment 10. 4D Systems - Workshop 4 IDE Workshop 4 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 Workshop 4 IDE.
4D SYSTEMS µLCD-43 Workshop 4 – ViSi Genie Environment ViSi Genie is a breakthrough in the way 4D Systems’ graphic display 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.
