Set scale for ADC

[Micka]

Hello @alex.tx
Thanks for clarification.
I’m basing it on this reply where your colleague wrote that up to 3.3V is supported

How can i minitor voltages on apalis imx6?

Connect the voltage to the AN1_ADC0 pin. (Allowed voltage range 0…3.3V). Read the file /sys/bus/iio/devices/iio:device0/in_voltage4_raw. The number read represents the voltage measured. The file /sys/bus/iio/devices/iio:device0/in_voltage_scale contains the multiplier to get from the raw ADC value to the voltage in milli volt.
