seyhmus.cacina 0:b259fd1a88f5 36 *
seyhmus.cacina 0:b259fd1a88f5 37 * Desc: Example Code to get algorithm estimation results of Heart rate( HRM) and Blood
seyhmus.cacina 0:b259fd1a88f5 38 * Oxygen (SPo2) form sensor hub and display it on screen. Example starts by monitoring heart rate
seyhmus.cacina 0:b259fd1a88f5 39 * ans switches to blood oxygen monitoring via a button press (switch button)
seyhmus.cacina 0:b259fd1a88f5 40 *
seyhmus.cacina 0:b259fd1a88f5 41 * Example,
seyhmus.cacina 0:b259fd1a88f5 42 *
seyhmus.cacina 0:b259fd1a88f5 43 * 1. Initializes user interface
seyhmus.cacina 0:b259fd1a88f5 44 * initialize display screen and switch button for algo selection.
seyhmus.cacina 0:b259fd1a88f5 45 *
seyhmus.cacina 0:b259fd1a88f5 46 * 2. Initializes underlying hardware port for sensor hub communication:
seyhmus.cacina 0:b259fd1a88f5 47 * setup i2c comm. inits reset pin and mfio event pin and connects interrupt to mfio pin.
seyhmus.cacina 0:b259fd1a88f5 48 *
seyhmus.cacina 0:b259fd1a88f5 49 * 3. When switched to a minitoring mode
seyhmus.cacina 0:b259fd1a88f5 50 * disables previous algorithm, clears mfio event
seyhmus.cacina 0:b259fd1a88f5 51 * calls default init function for the sensor whose data is used by enabled algorithms. Algorithms are
seyhmus.cacina 0:b259fd1a88f5 52 * registered under sesnor instance for this example. Fcunction
seyhmus.cacina 0:b259fd1a88f5 53 * 1. initialize algorithm config struct enabled
seyhmus.cacina 0:b259fd1a88f5 54 * 2. enable data type to both raw sensor and algorithm data
seyhmus.cacina 0:b259fd1a88f5 55 * 3. get input fifo size to learn fifo capacity
seyhmus.cacina 0:b259fd1a88f5 56 * 4. set fifo threshold for mfio event frequency
seyhmus.cacina 0:b259fd1a88f5 57 * 5. reaenable sensor to acquire ppg data
seyhmus.cacina 0:b259fd1a88f5 58 * 6. enable accompanying accel sensor
seyhmus.cacina 0:b259fd1a88f5 59 * 7. enable switched algorithm
seyhmus.cacina 0:b259fd1a88f5 60 *
seyhmus.cacina 0:b259fd1a88f5 61 * 4. Sensor Hub now starts to write raw sensor/algorithm data to its data report FIFO which
seyhmus.cacina 0:b259fd1a88f5 62 * reports mfio event when data size determined by fifo threshold is written to report fifo.
seyhmus.cacina 0:b259fd1a88f5 63 *
seyhmus.cacina 0:b259fd1a88f5 64 * 5. Example calls SH_Max8614x_data_report_execute() which
seyhmus.cacina 0:b259fd1a88f5 65 * 1. calls SH API's sh_ss_execute_once() function which:
seyhmus.cacina 0:b259fd1a88f5 66 * writes sensor hub's report fifo content (sensor/algorithm data samples) to a buffer(1).
seyhmus.cacina 0:b259fd1a88f5 67 * 2. calls CSTMR_SH_FeedAccDataIntoSH() to send accelerometer data to sensor hub which os required for heart rate
seyhmus.cacina 0:b259fd1a88f5 68 * Note: SPo2 requires stablity so do not move/shake senor when taking SPo2 data.
seyhmus.cacina 0:b259fd1a88f5 69 * 3. Parses buffer(1) data to extract numeric sensor and algorithm samples according to enabled algorithms.
seyhmus.cacina 0:b259fd1a88f5 70 * look: whrm_data_rx() , wspo2_data_rx() , max8614x_data_rx() and sample structs whrm_mode1_data, wspo2_mode1_data and max8614x_mode1_data
seyhmus.cacina 0:b259fd1a88f5 71 *
seyhmus.cacina 0:b259fd1a88f5 72 * 6. numeric values are written to HrmResult, SPO2Result ... within MAX8614x whrm_data_rx() ... and included as extern in main.cpp
seyhmus.cacina 0:b259fd1a88f5 73 *
seyhmus.cacina 0:b259fd1a88f5 74 * 7. Example calls demoUI_display_algo_estimations() to display result on watch screen
seyhmus.cacina 0:b259fd1a88f5 75 *
seyhmus.cacina 0:b259fd1a88f5 76 *
