Multitrellis issue

by Moris526 on Thu Oct 08, 2020 5:16 pm

Hi.
I made a 32 Neotrellis units board.

If I just load 6 on the Arduino Multitrellis code it works fine. But If a go beyond that I start to get more and more issues like freezing or data errors.

Im new to electronics but I read it could be a Pullup resistors issue?

I attached a video with a rolling sequencer like light that skips steps or changes colour when a button is pressed

The first thing I'd to is make sure all the board interconnect solder joints are rock solid.

Yes. They are solid.

In fact, I can load any 6 units from the 32 in the multitrellis code and they work just fine.

The pullups theory couldnt be right?

Unlikely. They're all there, all the time.

All your address selector jumpers are correct?

You have adequate power to the trellises (trelli?)?

Someone suggested that I should remove some pullups...

No problem with the jumpers I think.

I supply power with 5v 10 amp transformer (220v here) connected at 6 different points around the edges.


I really want to make this work. Do you know if I can hire someone to help me?

You can post on the jobs board https://www.adafruit.com/jobs. Did you ask on discord.. #help-with-projects? There are no doubt others that have a 32 neotrellis build. I've only done the 4 trellis kit.
