getting started (continued) the graphics lcd controller pictail? plus ssd1926 board can be used in conjunction with the microchip graphics library. the microchip graphics library and other firmware examples can be downloaded from http://www.microchip.com/graphics . the microchip graphics library installer will create a start menu folder under programs\microchip\graphics library vx.xx . please refer to the ?getting started? section in the microchip graphics library help at this location to program and run demonstration projects. the graphics lcd controller pictail? plus ssd1926 board has a footprint for nand flash memory (u2). end designers may choose to install a nand flash (i.e., mt29f2g08aadwp). in which case, some modifications must be done. resistor, r15, should be removed and a zero ohm resistor, r18, should be installed to switch the chip select signal from the serial flash to the nand flash. software support for the nand flash and sd/mmc card is not available at initial release of hardware. please check the current release of the microchip graphics library for availability. a different display board may also be available, please check www.microchip.com/graphics for available options. if an end designer chooses to develop a custom display board, the included schematic shows the details of signal connections. do note that a different display may require modifications to the software provided with the microchip graphics library to function properly. also refer to the ssd1926 data sheet, table 6-10, as different interface modes may require different signals mapping. important: it is the user?s responsibility to obtain a copy of, familiarize themselves fully with, and comply with the requirements and licensing obligations applicable to third party tools, systems and/or specifications. this includes, but is not limited to, flash-based media and fat file systems available from sd card association, multimediacard association and microsoft ? corporation. signal interface for display connector pin no. symbol level description a1, b1 +9v +9.0v power supply a2, b2 gnd gnd ground a3, a4 +3.3v +3.3v power supply b3, b4 +5v +5.0v power supply a5, b5 gnd gnd ground a6 left/x- i/o touch panel left b6 top/y- i/o touch panel top a7 right/x+ i/o touch panel right b7 bottom/y+ i/o touch panel bottom a8 pen_int i pen interrupt (touch panel driver) b8 sense i 5-wire touch panel sense a9 sck o pic ? microcontroller sck b9 sdo o pic microcontroller sdo a10 sdi i pic microcontroller sdi b10 ss o pic microcontroller ss a11 bklht_en o enable for backlight driver b11 bklht_pwm o pwm output for backlight driver a12, b12 gnd gnd ground a13 shift o pixel shift signal b13 den o data enable for 24-bit digital rgb interface a14 frame o frame pulse b14 line o line pulse a15-a26, b15-b26 ldata0-ldata23 o 24-bit data a27 gpo (disp_on) o gpo can be configured for display on or as general purpose output b27 gpio0 (cs) i/o gpio0 can be used for spi cs or as general purpose i/o a28 gpio1 (sck) i/o gpio1 can be used for spi sck or as general purpose i/o b28 gpio2 (mosi) i/o gpio2 can be used for spi mosi or as general purpose i/o a29 gpio3 (miso) i/o gpio3 can be used for spi miso or as general purpose i/o a30-a31, b29-b31 nc ? not connected a32, b32 gnd gnd ground
