Hi Jeffrey,
I tried turning off the other interface options but it didn't work out.
I'm not sure if the MCC 172 is fully seated on the GPIO header but the green light is on and I cannot push it down further.
I do not have any other hats mounted on the stack as well. And no other applications were running at the same time.
I'm sure that I have installed the daqhats software on my Pi.
My Raspberry Pi was newly bought and have no problem with the SD card so far.
Thank you for all the possible solutions so far. Is there anything else I can do on my part?
Regards,
Xin Yu
