Example Host software for integration of MAX3266x chips (, MAX32664GWEB) equipped with Heart Rate from Wrist Algorithm. This is “stand-alone” software that runs on the MAX32630 low-power microcontroller to display heart rate on the display of the MAXREFDES101 reference design. It is intended provide a simple example of how to initialize and communicate with the sensor hub. Windows and Android communications are not supported.

gmehmet | 13:3d1a6b947396 | 37 | * Desc: Example Code to get algorithm estimation results of Heart rate( WHRM) from sensor hub and display |
gmehmet | 13:3d1a6b947396 | 38 | * it on screen. Example starts by monitoring heart rate |
gmehmet | 13:3d1a6b947396 | 39 | * and reinits algorithm via two consecutive button presses (switch button) |
gmehmet | 13:3d1a6b947396 | 40 | * |
gmehmet | 13:3d1a6b947396 | 41 | * Example, |
gmehmet | 13:3d1a6b947396 | 42 | * |
gmehmet | 13:3d1a6b947396 | 43 | * 1. Initializes user interface |
gmehmet | 13:3d1a6b947396 | 44 | * initialize display screen and switch button for algo selection. |
gmehmet | 13:3d1a6b947396 | 45 | * |
gmehmet | 13:3d1a6b947396 | 46 | * 2. Initializes underlying hardware port for sensor hub communication: |
gmehmet | 13:3d1a6b947396 | 47 | * setup i2c comm. inits reset pin and mfio event pin and connects interrupt to mfio pin. |
gmehmet | 13:3d1a6b947396 | 48 | * |
gmehmet | 13:3d1a6b947396 | 49 | * 3. When switched to a minitoring mode |
gmehmet | 13:3d1a6b947396 | 50 | * disables previous algorithm, clears mfio event |
gmehmet | 13:3d1a6b947396 | 51 | * calls default init function for the sensor whose data is used by enabled algorithms. Algorithms are |
gmehmet | 13:3d1a6b947396 | 52 | * registered under sesnor instance for this example. Fcunction |
gmehmet | 13:3d1a6b947396 | 53 | * 1. initialize algorithm config struct enabled |
gmehmet | 13:3d1a6b947396 | 54 | * 2. enable data type to both raw sensor and algorithm data |
gmehmet | 13:3d1a6b947396 | 55 | * 3. get input fifo size to learn fifo capacity |
gmehmet | 13:3d1a6b947396 | 56 | * 4. set fifo threshold for mfio event frequency |
gmehmet | 13:3d1a6b947396 | 57 | * 5. reaenable sensor to acquire ppg data |
gmehmet | 13:3d1a6b947396 | 58 | * 6. enable accompanying accel sensor |
gmehmet | 13:3d1a6b947396 | 59 | * 7. enable switched algorithm |
gmehmet | 13:3d1a6b947396 | 60 | * |
gmehmet | 13:3d1a6b947396 | 61 | * 4. Sensor Hub now starts to write raw sensor/algorithm data to its data report FIFO which |
gmehmet | 13:3d1a6b947396 | 62 | * reports mfio event when data size determined by fifo threshold is written to report fifo. |
gmehmet | 13:3d1a6b947396 | 63 | * |
gmehmet | 13:3d1a6b947396 | 64 | * 5. Example calls SH_Max8614x_data_report_execute() which |
gmehmet | 13:3d1a6b947396 | 65 | * 1. calls SH API's sh_ss_execute_once() function which: |
gmehmet | 13:3d1a6b947396 | 66 | * writes sensor hub's report fifo content (sensor/algorithm data samples) to a buffer(1). |
gmehmet | 13:3d1a6b947396 | 67 | * 2. calls CSTMR_SH_FeedAccDataIntoSH() to send accelerometer data to sensor hub which os required for heart rate |
gmehmet | 13:3d1a6b947396 | 68 | * 3. Parses buffer(1) data to extract numeric sensor and algorithm samples according to enabled algorithms. |
gmehmet | 13:3d1a6b947396 | 69 | * look: whrm_data_rx() , max8614x_data_rx() and sample structs whrm_mode1_data and max8614x_mode1_data |
gmehmet | 13:3d1a6b947396 | 70 | * |
gmehmet | 13:3d1a6b947396 | 71 | * 6. numeric values are written to HrmResult, within MAX8614x whrm_data_rx() and included as extern in main.cpp |
gmehmet | 13:3d1a6b947396 | 72 | * |
gmehmet | 13:3d1a6b947396 | 73 | * 7. Example calls demoUI_display_algo_estimations() to display result on watch screen |
gmehmet | 13:3d1a6b947396 | 74 | * |
