The 4D Arduino Adapter Shield provides a convenient interface to attach 4D Systems display modules to an Arduino platform without having to use jumper wires on the Arduino headers.
Communication to a 4D Systems Display Module is performed via your Arduino's serial port (RX and TX), and is provided via a simple 5-pin interface. A 5-pin cable is included for connection to the display module (the same cable as comes with the new PTU modules).
A single digital pin on the Arduino (D2) is utilized for an external reset of the display.
Power for the display is supplied from your Arduino's 5V bus. No external power is required for the Display Module as all power is supplied from the Arduino through the adapter.
This adapter features a stackable header design, enabling existing Arduino shields to connect to your Arduino through the adapter. Note however that this shield uses and provides only the legacy (R2 and earlier) Arduino pins, so you will not be able to stack an R3 shield on top of it without leaving the extra pins hanging. You could stack your shields the other way around, so that this shield stacks onto your R3 shield.
The lower image shows this adapter plugged into an Arduino, and a 4D Systems display module connected to this adapter.
The 4D Arduino Adapter Shield is compatible with the following 4D Systems display modules: While older modules from 4D Systems may be pin compatible, the 4D Arduino Library may not support them specifically.
The 4D Arduino Library is part of the 4D Workshop4 IDE Tool — see the Sample Menu for the Serial Environment.
