Tell us about yourself!

  • Hi, I'm having troubles getting the Pi to communicate with the Uno (100% legitimate Uno). When using the command "udevadm info -a -n /dev/ttyACM0 |less" I recieve a whole bunch of info with ATTRS{product} being "DWC OTG Controller" and the KERNELS being "usb1" (which doesn't seem correct). I have the web interface up and running and when I try and write to the Uno I get the error "Couldn't write to socket: [111] Connection refused Is the script running?". Any help getting the Pi interacting with the Uno would be greatly appreciated. Thanks in advance. Steve.
