+ *
+ *  Desc: Example Code to get algorithm estimation results of Heart rate( HRM) and Blood
+ *        Oxygen (SPo2) form sensor hub and display it on screen. Example starts by monitoring heart rate
+ *        ans switches to blood oxygen monitoring via a button press (switch button)
+ *
+ *        Example,
+ *
+ *        1. Initializes user interface
+ *                   initialize display screen and switch button for algo selection.
+ *
+ *        2. Initializes underlying hardware port for sensor hub communication:
+ *                   setup i2c comm. inits reset pin and mfio event pin and connects interrupt to mfio pin.
+ *
+ *        3. When switched to a minitoring mode
+ *                   disables previous algorithm, clears mfio event
+ *                   calls default init function for the sensor whose data is used by enabled algorithms. Algorithms are
+ *                   registered under sesnor instance for this example. Fcunction
+ *                   	        1. initialize algorithm config struct enabled
+ *                              2. enable data type to both raw sensor and algorithm data
+ *                              3. get input fifo size to learn fifo capacity
+ *                              4. set fifo threshold for mfio event frequency
+ *                              5. reaenable sensor to acquire ppg data
+ *                              6. enable accompanying accel sensor
+ *                              7. enable switched algorithm
+ *
+ *     4. Sensor Hub now starts to write raw sensor/algorithm data to its data report FIFO which
+ *        reports mfio event when data size determined by fifo threshold is written to report fifo.
+ *
+ *     5. Example calls SH_Max8614x_data_report_execute() which
+ *                 1. calls SH API's sh_ss_execute_once() function which:
+ *                            writes sensor hub's report fifo content (sensor/algorithm data samples) to a buffer(1).
+ *                 2. calls CSTMR_SH_FeedAccDataIntoSH() to send accelerometer data to sensor hub which os required for heart rate
+ *                    Note: SPo2 requires stablity so do not move/shake senor when taking SPo2 data.
+ *                 3. Parses buffer(1) data to extract numeric sensor and algorithm samples according to enabled algorithms.
+ *                    look: whrm_data_rx() , wspo2_data_rx() , max8614x_data_rx() and sample structs whrm_mode1_data, wspo2_mode1_data and max8614x_mode1_data
+ *
+ *     6. numeric values  are written to HrmResult, SPO2Result ... within MAX8614x  whrm_data_rx() ... and included as extern in main.cpp
+ *
+ *     7. Example calls demoUI_display_algo_estimations() to display result on watch screen
+ *
