MAX30100 on ESP32


Hello everyone,
I’m a student of the University of Salerno (UNISA) and I’m developping a simple driver to interface the ESP32 board to a MAX30100 (Datasheet).
The main problem is that I don’t know how to read Oxygen percentage and heart reat even if I set the correct mode. Now I’m able to read only temperature in burst read;
I attach the links to my code to this post.




your code seems ok, unfortunately that sensor does not provide direct values for heart rate and oxygen percentage which have to be somehow computed. Here you can find a library with some useful calculations.
