CONFIG_MAX30101_LED3_PA

LED2 (green) pulse amplitude

Type: hex

Help

Set the pulse amplitude to control the LED3 (green) 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
