 *
 * Use these steps to integrate the display module with your source code:
 * 1) Add scheduler and timer events which can provide a 1Hz update for the display EXTCOMIN pin
 *  	through a call to displayUpdate().  Include your scheduler/timer header files in the top of
 *  	display.c.  #define these values in appropriate header files:
 *  	#define SCHEDULER_SUPPORTS_DISPLAY_UPDATE_EVENT 1
 *  	#define TIMER_SUPPORTS_1HZ_TIMER_EVENT	1
 *  	and customize the line timerEnable1HzSchedulerEvent(Scheduler_DisplayUpdate) to make the
 *  	appropriate call to your timer/scheduler routine to start this event.
 *
 * 2) Add functions gpioEnableDisplay() and gpioSetDisplayExtcomin(bool high) to your gpio.c and
 * 		gpio.h files, and include
 * 		#define GPIO_SET_DISPLAY_EXT_COMIN_IMPLEMENTED 	1
 * 		and
 *		#define GPIO_DISPLAY_SUPPORT_IMPLEMENTED		1
 *		definitions in your gpio.h file
 *		** Note that the Blue Gecko development board uses the same pin for both the sensor and display enable
 *		pins.  This means you cannot disable the sensor for load power management if enabling the display.  Your
 *		GPIO routines need to account for this **
 *
 * 3) Call displayInit() before attempting to write the display and after initializing your timer and
 * scheduler.
