How can i minitor voltages on apalis imx6?
Does this article on the developer website answer your question?
No above article i am unable to get voltage.
please suggest me related answer
- 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.
i have connected 3.3v supply to AN1_ADC0.
and i tried following:
cat: read error : Invalid argument
how can i read in_voltage_scale ??
which bsp version are u using? I tried the
cat /sys/bus/iio/devices/iio\:device0/in_voltage_scale and this is working for me.
i am using bsp v2.7
can you give me the exact name of the bsp file you flashed?
sorry for dealy,
i flashed below bsp version and kernel branch
So you did your own build. Did you change anything (device tree, …) for the compilation?
