Can I run example code to test Navio2 sensors before quad build?

Update:
I found a post that seems to have the same issue:

with a reply

I understand now that the python examples aren’t working.

I tried the cat /sys/kernel/rcio/adc/ch0 command and have consistent readings over 5.2v using a 5V 2A power supply with nothing but a wireless dongle attached.

I was also able to run the C++ example ADC

pi@navio:~/Navio2/C++/Examples/ADC $ ./ADC
A0: 5.2740V A1: 0.0120V A2: 0.0240V A3: 0.0100V A4: 0.0320V A5: 0.0320V

Still getting same results when trying to run AccelGyroMag.
