I'm a beginner I don't know what part of the code is important and what I can get rid of. In the MAX3010x library, there are those examples for Heart rate and SpO2, but the code is large in both and I want one code to display both. Pox.getSpO2() \\ for getting oxygen saturation With MAX30100 we can get bot in a direct function: pox.getHeartRate() \\ for getting heart rate I'm trying to write a code for getting HeartRate and SpO2 readings and I'm using MAX30102 sensor. ![]()
