4D Systems OLED & LCD Display Shields for Arduino
4D Systems OLED & LCD Display Shields for Arduino provide an easy way of interfacing the 4DGL-platform OLED and LCD display modules to the Arduino-Duemilanove, Arduino-Mega, and many other Arduino compatible boards. The 4Display-Shield-96, 4Display-Shield-128, 4Display-Shield-160, and 4Display-Shield-144 come complete with a uOLED-96-G1, uOLED-128-G1, uOLED-160-G1, or uLCD-144 module, a 5 way multi-switch joystick and male headers that help connect the 4Display-Shield to the Arduino boards. The 5 position joystick is connected to the Arduino D2, D3, D4, D5, and D6 pins. The 4Display-Shield-22 includes a 4-wire resistive touch screen. The communication interface between the 4Display-Shield and the Arduino is via the Serial UART, or a combination of the SPI bus plus the analog/digital pins on the Arduino. Both the TX and RX signals are jumpered on the shield PCB so that the Arduino UART can be freed-up when it's being programmed. The 4DGL-platform OLED and LCD modules are each integrated with a full color OLED or LCD-TFT screen, the tiny yet poweful GOLDELOX graphics controller chip, and a micro-SD connector which supports standard and high-capacity memory cards. The memory card can be used to store images, icons, video clips, and data logging.
