CONFIG_MAX30101_LED1_PA
¶
LED1 (red) pulse amplitude
Type: hex
Help¶
Set the pulse amplitude to control the LED1 (red) 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
Default¶
0xff
