ENSMM
Test program for a Max30102 heartrate sensor on a STM32L476RG specific board ENSMM
Dependencies: mbed
These two pictures show how to connect the Mheuve Sensor to the ST-Link debugger (don't forget to disable ST-link jumpers and JP5 on the board! ):
These two pictures show how to connect the Mheuve Sensor TX RX to the ST-Link debugger (don't forget to cross TX and RX, it means Mheuve sensor TX on ST-Link RX and ST-Link TX on Mheuve sensor RX ):
The Mheuve sensor board needs to be powered by an external battery.
The result appears on the terminal, speed config is 115200 bds.
