CONFIG_MAX30101_SR

ADC sample rate control

Type: int

Help

Set the effective sampling rate with one sample consisting of one
pulse/conversion per active LED channel. In SpO2 mode, these means
one IR pulse/conversion and one red pulse/conversion per sample
period.
0 = 50 Hz
1 = 100 Hz
2 = 200 Hz
3 = 400 Hz
4 = 800 Hz
5 = 1000 Hz
6 = 1600 Hz
7 = 3200 Hz
