Hello,
As parts of this library (ex. the SpO2 module) is based off the original code by Maxim Integrated for their MAXREFDES117, can I use Sparkfun’s library to control Maxim’s MAXREFDES117 sensor (is it interchangeable)?
Yes, you can. You can use Dfrobot’s MAX30102 library too. Here is a tutorial.https://www.youtube.com/watch?v=H8_R4-F-p-A
