I have absolutely the same problem
so sir, how you fix it? just adding the level shiffter?
Well i figure its probably one of two things or maybe the combination of both:
1. Added the level shifter into the circuit.
2. Added another 5V line towards the middle of the led strip as well as also connected the 5V and ground at the end of the led strip. This way the current of 5V is consistant throughout the whole led strip which i believe is deffinately helping in that sense that the led strip is behaving/responding to commands better.
Can u link me to the level shifter you use?
BTW, I notice when I connect the 5V at the strip end to DO or DI in the beginning all the led is bright blue.
Sounds like a really bad idea connecting the 5V to the DO or DI line of the led.
I bought the level shifter here: https://thepihut.com/products/adafruit-74ahct125-quad-level-shifter-3v-to-5v-74ahct125
