I am trying to control a DC motor with encoder, using your HighSpeedEncder.

I started with the next statement.

wget -qO- http://www.phidgets.com/gpgkey/pubring.gpg | apt-key add -

This gave me error messages citing that I am not root user.
(probably due to Oh or zero -mistake in my typing/reading the command)

Therefore, I changed to the root by issuing
sudo su
The command brings me to the root user.
However, after several tries, I could not perform

sudo apt-get update

Since there were another error messages.

I'll appreciate it if you could guide me to some appropriate manual section.

Thanks,

Bryan.

Are you running a 32-bit Debian distribution?

You may have more luck compiling the libraries from source.

I have installed the most upto-date Raspbian Jessie 64bit, and connected a 7 inch LCD touchscreen.

Would the 32bit Raspbian Jessie version be more stable than 64bit equivalent?

Thank you so much for your help.

Dear Patrick,

Sorry for my ignorance. The reply above is totally misleading.

1.I don't think I had any choice in the 32bit or 64bit OS during my installation process of the Raspberry Pi 3.

I simply followed the instructions in the Installation guide steps.

2. When I issue 'sudo apt-get upgrade' command, it seems to work without any Error Messages.

Thanks again,

Bryan.
