Lowering the voltage fixed it and I traced the pink LEDS down to a bad (open) ground connection on one end. Long term I think I need to power the strips in the middle and have a bit of a rethink but for now I have a 4000 LED array that works well enough. Thanks for the help.

I have a large LED array (4000 LEDS) and most of it runs fine, but 3 of the strands glitch on certain videos/pictures but is stable the rest of the time. Lifting v+ on one end of the glitching lines stops the glitching (but then I lose my whites - they go pink). The flickering only occurs when...

It came back to life but it's still a bit flakey (not every upload will upload).

It's socketed and when I pull it out it makes no difference to uploading. There doesn't appear to be any damage to the switch, I cut the usb power trace with a craft knife when I got it but it's uploaded fine many times since. I'll try grounding the reset and see what that does (I'm away from...

I have a teensy 3.0 that has the octo ws2811 sketch running on it, I know the USB cable / chip still works because I can display video fine. When I try and upload new code pressing the reset button doesn't trigger the upload in the teensy bootloader application like it normally does. I have...

I'm interested in using the new audio library to read in data to a buffer for speech recognition using pocketsphinx. It runs on an ARM M4 mobile phone so it should be possible on the Teensy. I've got as far as downloading the library and have got stuck at the instructions for the compiling the...

I’m working on a large WS2811 LED pixel strip array for an art installation. At the moment I’m working on the prototype (1000 leds at 3cm pitch on a frame 150cm in length with 20 rows of LEDS). I’ve had 9 rows wired up and have been connecting power and ground at either end of the 1.5m...
