Dotstar panel not working when connected

by jessgingery on Wed Sep 11, 2019 12:25 am

Hi,

Im using 4 x Flexible Adafruit DotStar Matrix 16x16 parts and 2 of them are working perfectly when connected to a bluefruit.

Since we only just plugged them all together to create a scrolling sentence, we have seen that 1 of the matrix 16 x 16 panels has an LED that lights up green permanently in the bottom right corner.

The other panel is not lighting up at all when connected.

We have swapped it out into different combinations and know for sure that there is something wrong with this particular panel.

Did you test the panels individually before chaining them together? If not, can you backup with your wiring and somehow do that now?

HI there,

I have wired each matrix panel to power via the bluefruit individually.

All but three respond, the last one does not.
