I am using an FX30 from the Linux console (SSH connection) and I would like to use the ADC1 (pin 5, IO2 of the power cable).
The read command always reports the same value regardless of of the power I apply on the PIN5.
Command used: $> cat /sys/class/hwmon/hwmon0/device/mpp_05 Response obtained: Result:9948 Raw:24796
As required by the FX30 user manual, I set the pull-up OFF by the following command:
$> echo 0 > /sys/class/gpio/gpio53/value
Could you advise on the commands to use to obtain a good reading?
Best regards, Christian.
