LCD TFT Module w/ Resistive Touchscreen, 4.3" QVGA, 4DGL/Serial

Description

LCD TFT Module w/ Resistive Touchscreen, 4.3" QVGA, 4DGL/Serial
uLCD-43PT
The µLCD-43PT is a compact and cost-effective intelligent display module packed with plenty of features, ready to be the GUI or interface controller for your target application. An extensive range of hardware and software peripherals are integrated into the design so you have freedom to adapt the module to suit your application.
The module consists of a 4.3-inch (480×272) LCD with resistive touch screen, an audio amplifier with speaker, a microSD card connector, and a group of GPIO including I2C and serial comms.
The PICASO processor on this module is driven by a highly optimized virtual core engine — the Extensible Virtual Engine (EVE). EVE is a high-performance virtual processor with an extensive byte-code instruction set optimized to execute compiled programs written in the 4D Graphics Language (4DGL).
4DGL is a graphics-oriented language allowing you to write applications in high-level code with syntax similar to popular languages such as BASIC, C and Pascal. The 4DGL-Workshop4 IDE (editor, compiler and downloader) also features the ViSi-Genie, a drag-and-drop graphical interface that will create 4DGL code for you — all you need to do is place pre-made objects onto a simulated image of the display, size and set parameters to your liking, then a single click will generate the 4DGL code to make that object functional.
Using the Workshop IDE, the module also can be loaded with a Serial Application that transforms it into a Serial Slave to virtually any serial host.
The PICASO processor on the display module also can be re-programmed with different ‘Personality Module Micro-Code’ (PmmC) files for updates and future proofing. The processes of converting to a serial slave, updating the PmmC firmware, or downloading your 4DGL program code all require connection of a USB converter that uses the DTR signal to pulse the Reset line on the processor. Two converters that can plug directly into this module are available from the "Optional Recommended Products" list below.

Four different usage methods
The 4D Systems Workshop 4 IDE supports multiple development environments, to cater for different user requirements and skill level.
The
Designer
environment enables you to write 4DGL code in its natural form to program the display module.
The
ViSi
visual programming experience enables drag-and-drop placement of objects to assist with 4DGL code generation and allows you to visualize how the display will look.
The
ViSi-Genie
advanced environment doesn't require any 4DGL coding at all; it is done automatically for you. Simply lay out the display with the objects you want (similar to ViSi), set the events to drive them and the code is written for you automatically. Arduino and Raspberry Pi libraries are available for use with ViSi-Genie.
The
Serial
environment is provided to transform the display module into a slave serial display module, allowing you to control the display from any host microcontroller or device with a serial port. Serial libraries are available for C, Pascal, PicAxe, and Arduino.
By default, the module will come ready for Serial usage. You can change environments or customize the serial firmware using a programming cable and the
Workshop 4
IDE software.
