+///
+/// @mainpage RA8875 Display Controller Driver library
+///
+/// The RA8875 Display controller is a powerful interface for low cost displays. It
+/// can support displays up to 800 x 600 pixels x 16-bit color. Another common
+/// implementation is 480 x 272 x 16 with two layers. The two layers can be
+/// exchanged, or blended in various ways (transparency, OR, AND, and more).
+/// It includes graphics acceleration capabilities for drawing primitives,
+/// such as line, rectangle, circles, and more.
+///
+/// The controller additionally supports backlight control (via PWM), keypad scanning
+/// (for a 4 x 5 matrix) and resistive touch-panel support.
+///
+/// @section Display_Config Display Configuration
+///
+/// This section details basics for bringing the display online. At a minimum,
+/// the display is instantiated. After that any of the available commands
+/// may be issued.
+///
+/// During the instantiation, the display is powered on, cleared, and the backlight
+/// is energized. Additionally, the keypad and touchscreen features are activated.
+/// It is important to keep in mind that the keypad had the default mapping, and
+/// the touchscreen does not have the calibration matrix configured, so additional
+/// steps may be necessary.
+///
+/// @code
+/// RA8875 lcd(p5, p6, p7, p12, NC, "tft");
+/// lcd.init();
+/// lcd.foreground(Blue);
+/// lcd.line(0,0, 479,271);
+/// ...
+/// @endcode
+///
+/// @section Touch_Panel Touch Panel
+///
+/// The supported touch panel interface is for a resistive panel, and is natively
+/// supported by the RA8875 controller. There are a few steps to enable this interface.
+///
+/// @subsection Touch_Panel_Enable Touch Panel Enable
+///
+/// @see TouchPanelInit has two forms - fully automatic, and controlled. See the APIs for
+/// details.
+///
+/// @subsection Touch_Panel_Calibration
+///
+/// The touch panel is not initially calibrated on startup. The application should
+/// provide a means to activate the calibration process, and that should not require
+/// the touchscreen as it may not yet be usable. Alternately, a calibration matrix
+/// can be loaded from non-volatile and installed.
+///
+/// @section Keypad Keypad
+///
+/// The keypad has a default keypad mapping, but there is an API that permits
+/// installing a custom keymap.

+ *

+ * Argument(s): displayPtr (output) - Pointer to the calculated
+ * (true) display point.
+ * screenPtr (input) - Pointer to the reported touch
+ * screen point.
+ * matrixPtr (input) - Pointer to calibration factors
+ * matrix previously calculated
+ * from a call to
+ * setCalibrationMatrix()
+ *
+ *
+ * The function simply solves for Xd and Yd by implementing the
+ * computations required by the translation matrix.

+ * This file contains functions that implement calculations

+ * that suffers from multiple distortion effects: namely,
+ * translation, scaling and rotation.
+ *
+ * The following set of equations represent a valid display
+ * point given a corresponding set of touch screen points:
+ *
+ * /- -\
+ * /- -\ /- -\ | |
+ * | | | | | Xs |
+ * | Xd | | A B C | | |

+ * (Xs,Ys) represents the available touch screen
+ * coordinates, and the matrix

+ * C = Cn/Divider
+ * D = Dn/Divider

+/**********************************************************************
+ *
+ * Function: setCalibrationMatrix()
+ *
+ * Description: Calling this function with valid input data
+ * in the display and screen input arguments
+ * causes the calibration factors between the
+ * screen and display points to be calculated,
+ * and the output argument - matrixPtr - to be
+ * populated.
+ *
+ * This function needs to be called only when new
+ * calibration factors are desired.
+ *
+ *
+ * Argument(s): displayPtr (input) - Pointer to an array of three
+ * sample, reference points.
+ * screenPtr (input) - Pointer to the array of touch
+ * screen points corresponding
+ * to the reference display points.
+ * matrixPtr (output) - Pointer to the calibration
+ * matrix computed for the set
+ * of points being provided.
+ *
+ *
+ * From the article text, recall that the matrix coefficients are
+ * resolved to be the following:
+ *
+ *
+ * Divider = (Xs0 - Xs2)*(Ys1 - Ys2) - (Xs1 - Xs2)*(Ys0 - Ys2)
+ *
+ *
+ *
+ * (Xd0 - Xd2)*(Ys1 - Ys2) - (Xd1 - Xd2)*(Ys0 - Ys2)
+ * A = ---------------------------------------------------
+ * Divider
+ *
+ *
+ * (Xs0 - Xs2)*(Xd1 - Xd2) - (Xd0 - Xd2)*(Xs1 - Xs2)
+ * B = ---------------------------------------------------
+ * Divider
+ *
+ *
+ * Ys0*(Xs2*Xd1 - Xs1*Xd2) +
+ * Ys1*(Xs0*Xd2 - Xs2*Xd0) +
+ * Ys2*(Xs1*Xd0 - Xs0*Xd1)
+ * C = ---------------------------------------------------
+ * Divider
+ *
+ *
+ * (Yd0 - Yd2)*(Ys1 - Ys2) - (Yd1 - Yd2)*(Ys0 - Ys2)
+ * D = ---------------------------------------------------
+ * Divider
+ *
+ *
+ * (Xs0 - Xs2)*(Yd1 - Yd2) - (Yd0 - Yd2)*(Xs1 - Xs2)
+ * E = ---------------------------------------------------
+ * Divider
+ *
+ *
+ * Ys0*(Xs2*Yd1 - Xs1*Yd2) +
+ * Ys1*(Xs0*Yd2 - Xs2*Yd0) +
+ * Ys2*(Xs1*Yd0 - Xs0*Yd1)
+ * F = ---------------------------------------------------
+ * Divider
+ *
+ *
+ * Return: OK - the calibration matrix was correctly
+ * calculated and its value is in the
+ * output argument.
+ * NOT_OK - an error was detected and the
+ * function failed to return a valid
+ * set of matrix values.
+ * The only time this sample code returns
+ * NOT_OK is when Divider == 0
+ *
+ *
+ *
+ * NOTE! NOTE! NOTE!
+ *
+ * setCalibrationMatrix() and getDisplayPoint() will do fine
+ * for you as they are, provided that your digitizer
+ * resolution does not exceed 10 bits (1024 values). Higher
+ * resolutions may cause the integer operations to overflow
+ * and return incorrect values. If you wish to use these
+ * functions with digitizer resolutions of 12 bits (4096
+ * values) you will either have to a) use 64-bit signed
+ * integer variables and math, or b) judiciously modify the
+ * operations to scale results by a factor of 2 or even 4.
