4D Systems provides a series of compact and cost effective all in one 'SMART' display modules using the latest state of the art display technology including Active Matrix OLED (AMOLED), Passive Matrix OLED (PMOLED) and LCD TFT technology. 4D Systems also offer embedded VGA graphics modules, data storage, and USB to serial converters. 4D Systems develop the latest custom graphic processors, providing single chip solutions for most Graphics User Interface applications, all powered by the high level 4D Graphics.
Some display are available directly from this site from our display catalog.
The J16 connector on the FOX Board G20 is fully compatible with alle the 4DSystems displays.
This is the J16 pinout:
|Display Pin||Function||FOX Pin||Function||Description|
|1||VCC In||J16.1||VCC out||5 volt DC power supply|
|3||TX||J16.2||ttyS3 RX||Display asynchronous TX data|
|5||RX||J16.3||ttyS3 TX||Display asynchronous RX data|
|9||RESET||J16.5||N.C.||Display reset line. Not connected on the FOX Board|
An adapter called DAISY-15 is available to transform the 4DSystems display in Daisy system modules to plug directly on Terra Board os DAISY-1 through flan cables.
The 4DSystems display equipped with PICASO chip can works differents firmwares:
This two example in Python shows how to send command to the
The usage is:
debarm:/# ./4dprint.py -x 0 -y 0 -s 'Hello World !' -b
-x -y are the position (x=0, Y=0 is the left up cornen) -s is the string to print -b to erase the screen before print
FLAT-20CM - Flat cable 10 wires, 20 cm, pitch 1.27 mm
Ribbon cable for YARM-DEV or DAISY modules wiring:
IDC-FLAT - IDC socket 1.27mm for Daisy flat cable
IDC connector with 1.27mm spaced dual-row pin headers. The insulation displacement (IDC) contacts on these connectors allow them to be quickly and easily crimped onto FLAT-20CM flat ribbon cable for Daisy cabling system.
This female socket is designed to be connected to the male header on the Daisy modules. A polarizing tab in the middle ensures the correct orientation.
