Yet another USB connection problem... #7

Closed Black-Zero closed 2 years ago

Black-Zero commented 3 years ago

Hello,

today I tried to connect the Arduino with my MagicMirror. And nothing happens. After digging in how to debug I found the following line in the console output [2021-03-19 00:37:56.638] [LOG] 2021-03-19T00:37:56 <log> Fri Mar 19 2021 00:37:56 GMT+0100 (Mitteleuropäische Normalzeit): exec error: Error: Command failed: ls /dev/ttyUSB* ls: Zugriff auf '/dev/ttyUSB*' nicht möglich: Datei oder Verzeichnis nicht gefunden It seems that he doesn't get access to the usb port.

Installed serialport Version is 9.0.7. Installing a 4.x.x Version just drops me a bunch of errors...

How can I proceed to get it working? Thank you very much!

Greetings,

Black-Zero

Hello,

I got it responding to my MagicMirror. I had to change back from ttyUSB to ttyACM.

At 1st I checked, if the Arduino has been recognised by the raspberry via entering "lsusb" into the terminal. It had been recognised as Device 0004. 2nd: With "mesg" at the terminal I could figure out, that the Arduino hab been installed as ttyACM.

Greetings,
