gmehmet 0:ddc2fef69ef9 36 *
gmehmet 0:ddc2fef69ef9 37 * Desc: Example Code to get algorithm estimation results of Heart rate( HRM) and Blood
gmehmet 0:ddc2fef69ef9 38 * Oxygen (SPo2) form sensor hub and display it on screen. Example starts by monitoring heart rate
gmehmet 0:ddc2fef69ef9 39 * ans switches to blood oxygen monitoring via a button press (switch button)
gmehmet 0:ddc2fef69ef9 40 *
gmehmet 0:ddc2fef69ef9 41 * Example,
gmehmet 0:ddc2fef69ef9 42 *
gmehmet 0:ddc2fef69ef9 43 * 1. Initializes user interface
gmehmet 0:ddc2fef69ef9 44 * initialize display screen and switch button for algo selection.
gmehmet 0:ddc2fef69ef9 45 *
gmehmet 0:ddc2fef69ef9 46 * 2. Initializes underlying hardware port for sensor hub communication:
gmehmet 0:ddc2fef69ef9 47 * setup i2c comm. inits reset pin and mfio event pin and connects interrupt to mfio pin.
gmehmet 0:ddc2fef69ef9 48 *
gmehmet 0:ddc2fef69ef9 49 * 3. When switched to a minitoring mode
gmehmet 0:ddc2fef69ef9 50 * disables previous algorithm, clears mfio event
gmehmet 0:ddc2fef69ef9 51 * calls default init function for the sensor whose data is used by enabled algorithms. Algorithms are
gmehmet 0:ddc2fef69ef9 52 * registered under sesnor instance for this example. Fcunction
gmehmet 0:ddc2fef69ef9 53 * 1. initialize algorithm config struct enabled
gmehmet 0:ddc2fef69ef9 54 * 2. enable data type to both raw sensor and algorithm data
gmehmet 0:ddc2fef69ef9 55 * 3. get input fifo size to learn fifo capacity
gmehmet 0:ddc2fef69ef9 56 * 4. set fifo threshold for mfio event frequency
gmehmet 0:ddc2fef69ef9 57 * 5. reaenable sensor to acquire ppg data
gmehmet 0:ddc2fef69ef9 58 * 6. enable accompanying accel sensor
gmehmet 0:ddc2fef69ef9 59 * 7. enable switched algorithm
gmehmet 0:ddc2fef69ef9 60 *
gmehmet 0:ddc2fef69ef9 61 * 4. Sensor Hub now starts to write raw sensor/algorithm data to its data report FIFO which
gmehmet 0:ddc2fef69ef9 62 * reports mfio event when data size determined by fifo threshold is written to report fifo.
gmehmet 0:ddc2fef69ef9 63 *
gmehmet 0:ddc2fef69ef9 64 * 5. Example calls SH_Max8614x_data_report_execute() which
gmehmet 0:ddc2fef69ef9 65 * 1. calls SH API's sh_ss_execute_once() function which:
gmehmet 0:ddc2fef69ef9 66 * writes sensor hub's report fifo content (sensor/algorithm data samples) to a buffer(1).
gmehmet 0:ddc2fef69ef9 67 * 2. calls CSTMR_SH_FeedAccDataIntoSH() to send accelerometer data to sensor hub which os required for heart rate
gmehmet 0:ddc2fef69ef9 68 * Note: SPo2 requires stablity so do not move/shake senor when taking SPo2 data.
gmehmet 0:ddc2fef69ef9 69 * 3. Parses buffer(1) data to extract numeric sensor and algorithm samples according to enabled algorithms.
gmehmet 0:ddc2fef69ef9 70 * look: whrm_data_rx() , wspo2_data_rx() , max8614x_data_rx() and sample structs whrm_mode1_data, wspo2_mode1_data and max8614x_mode1_data
gmehmet 0:ddc2fef69ef9 71 *
gmehmet 0:ddc2fef69ef9 72 * 6. numeric values are written to HrmResult, SPO2Result ... within MAX8614x whrm_data_rx() ... and included as extern in main.cpp
gmehmet 0:ddc2fef69ef9 73 *
gmehmet 0:ddc2fef69ef9 74 * 7. Example calls demoUI_display_algo_estimations() to display result on watch screen
gmehmet 0:ddc2fef69ef9 75 *
gmehmet 0:ddc2fef69ef9 76 *
