Graphics Display Truly 5.7" 640 x 480 Board Information Sheet
Features
• 5.7” VGA (640 x 480) TFT display with 24-bit parallel RGB interface and 4-wire resistive touch
interface
• Resistive touch controller (AR1020) interfaced to the MCU through the SPI module
• Additional direct interface to MCU for 4-wire resistive touch signals
Getting Started
To get started, a display controller board with a display connector, such as the Graphics Controller
PICtail™ Plus Epson S1D13517 Board (AC164127-7), is required. For details, refer to the related
documentation (DS51948).
The Graphics Display Truly 5.7" 640 x 480 Board can be used with a display controller board in con-
junction with the Graphics Library for Microchip microcontrollers. The Microchip Graphics Library
and other firmware examples can be downloaded from http://www.microchip.com/graphics. Please
refer to the “Getting Started” topic in the Microchip Graphics Library Help file in the Microchip
Application Library (MAL) for information on using the board.
Board Settings
• Jumpers J1, J2, J3, and J4, select between the AR1020 touch controller interface and direct
MCU interface for touch signals. J1-4 on positions 2-3 select the MCU interface, and on
positions 2-1, selects the AR1020 touch interface (on positions 2-3 by default).
• Jumper J5 connects the interrupt signal, PEN_INT, from the display connector to the LED
anode, which is used as a visual indication utility (closed by default)
