Reads the conversion results, measuring the voltage difference between the P (AIN0) and N (AIN1) input. Generates a signed value since the difference can be either positive or negative.

Reads the conversion results, measuring the voltage difference between the P (AIN0) and N (AIN1) input. Generates a signed value since the difference can be either positive or negative.
DEV@/ads1115-device
An ADS1115 device.
UPDpulse
Update
Donepulse
Pulse on read.
Valuenumber
ADC reading in raw counts.
To use the node in your project you should have the wayland/ads1115 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.
