Hi!
We have a created this led dress which consist of 13 led strips controlled by a teensy. The whole setup is as follows:
A macbook is streaming LED values via Wifi using Cycling 74s Max software. The values are received by a Raspberry Pi 3 (in the LED dress) using Pure Data. The RPi also upack the values, and then send them via COMPORT to a Teensy 4.1. The Teensy write the values to the LED strips using OctoWS2811. Each LED strip is powered by a 5V reachargeable battery.
The setup has been working perfectly util recently. Suddenly the RPi lost contact with the Teensy. The Teensy did not show up on the RPi any more, and the orange LED on Teensy kept blinking. It was almost like when i power up a new teensy with the blink sketch.
We then uploaded the code once more to the Teensy, and now it works like a charm again.
But it would be a disaster if this happened during a performance, and i was hoping that someone could shed some light on what happened so we can avoid this problem in the future. Anyone experienced anything similar.
(The teensy is mounted inside a box, so should not be possible to touch anything and mess stuff up)
Best,
Pål Asle
