Graphics Display Truly 7" 800 x 480 Board Information Sheet Features • 7" WVGA (800 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 7" 800 x 480 Board can be used with a display controller board in conjunction 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.
