Matrix-odas -- can't open any device


#1

Hi,

I have a Matrix Creator/Raspberry Pi 3 Model B. I just installed ODAS by following the instructions given at https://www.hackster.io/matrix-labs/direction-of-arrival-for-matrix-voice-creator-using-odas-b7a15b.

The installation went smoothly, but I got an error: can’t open any device when running
~/odas/bin/matrix-odas. Can someone help me resolve this problem?

Thanks,

David

Okay. I tried troubleshooting by following the instructions on this page (https://matrix-io.github.io/matrix-documentation/matrix-creator/troubleshooting/), and I am now able to run the following two programs,
~/odas/bin/matrix-odas & and ~/odas/bin/odaslive -vc …/config/matrix-demo/matrix_creator.cfg. However, the matrix-odas app does not lit up the LEDs. I also tested the MATRIX Everloop demo program and LEDs are not working either. Can someone explain how to resolve this problem?

Thanks,

David

Hi @david,

I would recommend starting with a fresh installation of Raspbian stretch. Test the everloop LED example first to ensure the LEDs are working and then try the ODAS example again.

I have not seen your error before so it may be something that went wrong during the installation.

If the problem still persists after trying again, let us know and we will look into it more.

Best,
Samreen
