Maxim Integrated / Mbed OS Host_Software_MAX32664GWEB_HR_wrist

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.

Dependencies:   Maxim_Sensor_Hub_Communications BMI160 whrmDemoUI max32630hsp3
