   1 OVERVIEW
   2 ============================================================
   3 This examples simulates a very crude oscilloscope, and
   4 reads the values on an analog input pin (P1.4/Wakeup, which
   5 can be configured as AD5) as well as a digital pin (P2.0).
   6 The digital pin will simply be displayed as 'High' (3.3V)
   7 or 'Low' (0V/GND).
   8
   9 The last 10 readings are rendered in a data grid on the LCD,
  10 with new readings added approximately every 100ms.

  12 This sample demonstrates the following features
  13 ============================================================
  14
  15 - Rotating the LCD orientation
  16 - Rendering text with different colors and fonts
  17 - Using the touch screen to enable or disable a feature
  18
  19 WARNING
  20 ============================================================
  21 Please note that the ADC pins on the LPC1343 are NOT 5.0V
  22 tolerant.  Supply more than 3.3V to an ADC pin will
  23 permanently damage the MCU.  Digital I/O pins are 5.0V
  24 tolerant and can safely test 5.0V logic.

  26 Pin Usage
  27 ============================================================
  28 This examples is based on the LPC1343 TFT LCD Stand-Alone
  29 board, which has a very limited number of pins broken out.
  30 P1.4 can be configure as GPIO, but also as WAKEUP and AD5.
  31
  32 This pin is also available on the LPC1343 Reference Design
  33 Base Base and is marked as WAKEUP on the PCB, but it has
  34 a 10K pullup on it to allow the pin to function as a WAKEUP
  35 source.

  38 the schematics available in the ~/tools/schematics folder.
