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.

Example starts by monitoring heart rate + * and reinits algorithm via two consecutive button presses (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 + * 3. Parses buffer(1) data to extract numeric sensor and algorithm samples according to enabled algorithms. + * look: whrm_data_rx() , max8614x_data_rx() and sample structs whrm_mode1_data and max8614x_mode1_data + * + * 6. numeric values are written to HrmResult, 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 + * + * + ***********************************************************************************/ + +#include <events/mbed_events.h> +#include <mbed.h> +#include "max32630hsp.h" +#include "SHComm.h" +#include "bmi160.h" +#include "whrmDemoUI.h" + +#include "SH_Max8614x_WHRM.h" + + +extern uint16_t HrmResult; +extern uint8_t HrmConfidence; + + +DigitalOut led1(LED1, 1); +// Hardware serial port over DAPLink +Serial daplink(USBTX, USBRX, 115200); +// ICARUS Board initialization +InterruptIn interruptIn_PowerButton(P7_6); +MAX32630HSP icarus(MAX32630HSP::VIO_1V8, &interruptIn_PowerButton); + +#define WAIT_SENSORHUB_STABLE_BOOTUP_MS ((uint32_t)2000) + + +static bool isWhrmInitialized = false; + + +int main() { + + wait_ms(WAIT_SENSORHUB_STABLE_BOOTUP_MS); + demoUI_init(); + + sh_init_hwcomm_interface(); + sh_disable_irq_mfioevent(); + sh_clear_mfio_event_flag(); + sh_enable_irq_mfioevent(); + int i = 0; + + int displayMode; + uint16_t resultToDisplay; + uint8_t confidenceToDisplay; + + while(1) { + + displayMode = demoUI_display_get_mode(); + + if( displayMode == kAlgoModeHeartRate ){ + if( !isWhrmInitialized){ +#if defined(DEBUG_INFO) + printf(" WHRM inititalized \r\n"); +#endif + SH_Max8614x_stop(); + SH_Max8614x_default_init(kAlgoModeHeartRate); + isWhrmInitialized = true; + wait_ms(1000); /* for display screen*/ + } + resultToDisplay = HrmResult; + confidenceToDisplay = HrmConfidence; + + }else{ + + demoUI_display_set_algoMode(kAlgoModeHeartRate); + isWhrmInitialized = false; + } + + int cumSampleCNt = SH_Max8614x_data_report_execute(); + if(cumSampleCNt){ +#if defined(DEBUG_INFO) + printf("estimate: =%d conf: %d dispMode: %d \r\n", resultToDisplay , confidenceToDisplay, displayMode); +#endif + demoUI_display_algo_estimations(resultToDisplay); + + } + + + + } + +}
