CONFIG_MAX30101_LED2_PA

LED2 (IR) pulse amplitude

Type: hex

Help

Set the pulse amplitude to control the LED2 (IR) current. The actual
measured LED current for each part can vary significantly due to the
trimming methodology.
0x00 = 0.0 mA
0x01 = 0.2 mA
0x02 = 0.4 mA
0x0f = 3.1 mA
0xff = 50.0 mA

Direct dependencies

MAX30101 && SENSOR

(Includes any dependencies from ifs and menus.)

Default

0x33
