I'm using the following shell script that writes all AIN values to the
console in a loop.
#!/bin/sh
while : ; do
for i in 4 5 6 ; do
echo -n "AIN${i}: `cat
/sys/devices/ocp.2/44e0d000.tscadc/tiadc/iio\:device0/in_voltage${i}_raw` "
sleep 1
done
echo ""
done
Then use a jumper to short the analog input. After one or two readings,
the corresponding AIN
value should be (close to) zero as in the output shown below:
AIN4: 3626 AIN5: 3631 AIN6: 3630
AIN4: 3628 AIN5: 3631 AIN6: 3628
AIN4: 3628 AIN5: 3631 AIN6: 3
AIN4: 3628 AIN5: 3631 AIN6: 1
AIN4: 3628 AIN5: 3632 AIN6: 3629
AIN4: 33 AIN5: 3633 AIN6: 3630
AIN4: 40 AIN5: 3632 AIN6: 3630
AIN4: 39 AIN5: 3632 AIN6: 3629
Note: I've only tested this with the cape-bebopr-brdg device tree
overlay loaded, but I guess
it should also work with Charles' overlay. Do check the output of
"dmesg | grep capemgr" to
make sure the proper one is loaded!
