+  The LPC1766-STK has a Nokia 6100 132x132 LCD and either a Phillips PCF8833
+  or an Epson S1D15G10 LCD controller.  The NuttX configuration may have to
+  be adjusted depending on which controller is used with the LCD.  The
+  "LPC1766-STK development board Users Manual" states tha the board features
+  a "LCD NOKIA 6610 128x128 x12bit color TFT with Epson LCD controller."
+  But, referring to a different Olimex board, "Nokia 6100 LCD Display
+  Driver," Revision 1, James P. Lynch ("Nokia 6100 LCD Display Driver.pdf")
+  says:
+  
+  "The major irritant in using this display is identifying the graphics
+   controller; there are two possibilities (Epson S1D15G00 or Philips
+   PCF8833). The LCD display sold by the German Web Shop Jelu has a Leadis
+   LDS176 controller but it is 100% compatible with the Philips PCF8833).
+   So how do you tell which controller you have? Some message boards have
+   suggested that the LCD display be disassembled and the controller chip
+   measured with a digital caliper – well that’s getting a bit extreme.
+
+  "Here’s what I know. The Olimex boards have both display controllers
+   possible; if the LCD has a GE-12 sticker on it, it’s a Philips PCF8833.
+   If it has a GE-8 sticker, it’s an Epson controller. The older Sparkfun
+   6100 displays were Epson, their web site indicates that the newer ones
+   are an Epson clone. Sparkfun software examples sometimes refer to the
+   Philips controller so the whole issue has become a bit murky. The
+   trading companies in Honk Kong have no idea what is inside the displays
+   they are selling. A Nokia 6100 display that I purchased from Hong Kong
+   a couple of weeks ago had the Philips controller."
+
+  The LCD connects to the LPC1766 via SPI and two GPIOs.  The two GPIOs are
+  noted above:
+  
+    P1.21 is the SPI chip select, and
+    P3.25 is the LCD reset
+    P3.26 is PWM1 output used to control the backlight intensity.
+  
+  MISO0 and MOSI0 are join via a 1K ohm resistor so the LCD appears to be
+  write only.
