Hi Paul,
I followed your suggestion and, unbelievably enough, I found that the problem is in the level shifter. :-O
I can't really understand how can a 74HCT245 enter this state... I hope it's a faulty device,...
Ok.
I don't know for sure, I'm just guessing.
Between the serial ports and the strips there's a single 8-port level converter (74HCT245) followed by a 100ohm resistor for each port.
What makes me think of the...
It happened again, after many hours.
Right now all my LED strips, connected to Teensy 4.1 Serial 1, 3, 4 and 7 and frozen, but the program is running.
I can use the serial monitor or the infrared remote to interact...
I'm using Teensy 4.x Serial ports for driving LED strips via WS2812Serial, either directly or indirectly via FastLED and they seem to freeze at random times (all LED strips at the same time). This happens especially...
Update
Ha! It happened with the WS2812Serial-only (no FastLED) version too.
That restricts the search quite a lot and probably exonerates FastLED.

Hi everyone,
I've developed a library for Teensy 4 + Audio Adapter board, based on FastLED + WS2812Serial and built a physical project on it.
Code, photos and detailed documentation is here:...
I've developed a library specific for Teensy 4 + Audio Board to simplify the development of complex sound reactive effects for LED strips, and to provide runtime support for rendering simultaneous effects on multiple...
