I want to make ADC samples on this kit. But the ADC does not appear in the sys/bus/iio/devices folder, so I need to activate the ADC part. I followed the instructions given for this. I saw the ADC pins that I defined in the file, but when I type the cat command on these pins, I can't see any change as a result. The resulting values are always the same. When I connect the ADC pin to GND, the value does not change, even when I apply any other voltage, the pins I have defined always show the same value. I couldn't find anything on this topic. Can you help me? DTB file attached
