Hello

I just received my Teensy 3.2 and I meet a little problem with leds WS2812B. I use as recommended a SN74HCT245 to convert my signal from 3V3 to 5V. The problem is that I turn on all the LED glows white: / I have double checked my wiring. On the other hand, when I connect DIN directly to pin 2 the everything works oO

I do not understand why with the 74HCT it does not work ..

Thank you
 
Something is almost certainly wired up wrong. I know you double checked, but if you want us to help, you need to share photos of the wiring.
 
Thanks for your fast reply!

I made all the cables, I always disconnect anything and I say to myself "And if it was the 74hct is the problem" I replace it with another chip and bingo it works!

You really need to check everything ^^

Thank you
