I know mate! When I was planning the project I thought I would save some money going through the Teensy route. I was aware it was going to be time consuming and full of head scratches but it also was the beginning of lock-down in my country so I didn't mind some problem solving to keep me busy. :lol...

I tried reducing the LED count from the Arduino sketch but when I go lower than the actual number of LEDs on the strip the behaviour gets worse. The whole strips starts going crazy. I'm kind of stuck with this project, going through the Arduino sketch for animation is going to be too time consuming ...

I am using FastLED 3.3.0 and at the moment I have two parallel output of 120 pixel each. I tried the FastLED-simple-test.ino and it works properly, same goes for other Examples sketches from FastLED library, except some problem with FastLED.delay(). But when I uncomment #define JUST_TEST_LEDS on the...

Still not working properly.

I also tried the example sketches from FastLED library and they don't work properly either, while the ones from Neopixel, like the strandtest, work perfectly.

I think that should mean that the problem is not in the wiring or soldering, right?

Thanks for the reply mad-matt. Changing bytesRead<30000 to 3000 did not work. And yes I was following the new FastLED parallel protocol for the Teensy 4 Dalready. I have also added a level shifter since last time I wrote. Essentially now everything works but with some random pixels blinking each sid...

I thought I'd add a video to show the behaviour and also the code I'm running on Tennsyduino:

Hi guys! I am putting together a project with 300 LEDs arranged in 5 strip of one meter each. I am using a Teensy 4.0 and WS2812b powered through a 5v PSU. At the moment though I am only testing a single strip of 60 LED, with the same set up. I get the 60 pixels strip to run the "JUST_TEST_LEDS" alm...

I also have a similar but slightly different problem when connecting Teensy 4.0 and WS2812b to MadMapper. I get the 60 pixel strip to run the "JUST_TEST_LEDS" almost fine as all LED blink as expected apart from the first one which stays on. When I then go into MadMapper something really weird happen...
