Max30101 class
Constructors
- Max30101(I2CWrapper wrapper, bool captureSamples, {double ledPower = 6.4, int ledsEnabled = 2, int sampleRate = 100, int sampleAverage = 1, int pulseWidth = 411, int adcRange = 16384, bool highResMode = true, bool debug = true})
- Check table 8 in datasheet on page 19. You can't just throw in sample rate and pulse width randomly. 100hz + 1600us is max for that resolution device is injectable so you can inject mocks / whatever for testing purposes
