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

Direct dependencies¶

MAX30101 && SENSOR

(Includes any dependencies from if’s and menus.)

Defaults¶

0 if MAX30101 && SENSOR
