Matrix Creator ODAS demo, some LEDs don't work?

#1

I have a matrix creator on a Raspberry Pi 3. I went through the ODAS demo setup in https://www.hackster.io/matrix-labs/direction-of-arrival-for-matrix-voice-creator-using-odas-b7a15band it appeared to be working, but when testing it I found that LEDs D22 through 35 don’t light up. It seems to be tracking sounds ok and follows the sound of me scratching my fingers on the desk, but sound sources opposite D22 through 35 don’t cause the leds to light.

I thought maybe I could troubleshoot by installing ODAS-WEB but this is not working for me either. When I try to do the nrpm install I get a raft of errors.

Any ideas on how to fix?

#2

Update, I went to the HAL demos and ran some of them. Running everloop or any of the other demos that light LEDs, the LEDs 22-35 never light up, the other leds work normally.

when doing the fpga test it indicated 1000A instead of 10008 as it said.

#3

Hi @Greg_Corson,

1000A is the latest MATRIX Creator FPGA firmware version so that is okay.

You said you are using the MATRIX Creator w/ the RPi 3, what is your OS, Raspbian Stretch or Buster?

Apologies for the delayed response, missed the post. If the issue persists on Raspbian Stretch for HAL examples, it is possible that those LEDs have some physical issue.

Best,
Samreen
