wayland/as7341-spectrometer/set-gain

Set the ADC gain multiplier.

set-gain

@/set-gain

Set the ADC gain multiplier.

DEV@/as7341-device

An as7341-device.

GAINnumber

ADC gain multiplier. Can take values of: 0.5, 1, 2, 4, 8, 16, 32, 64, 128, 256 and 512.

UPDpulse

Update.

DONEpulse

Pulses if gain is successfully set.

To use the node in your project you should have the wayland/as7341-spectrometer library installed. Use the “File → Add Library” menu item in XOD IDE if you don’t have it yet. See Using libraries for more info.
