I have a Teensy 4.0 connected to an OctoWS2811 adapter that I plan to use to drive some LEDs. I loaded the BasicTest_RGBW program and plugged it into a strand of WS2812B LEDs. It appeared to work fine, displaying pixels in six different colors (and some unlit pixels) that change every couple seconds. Then I tried plugging it into a different strand of WS2812Bs and it displayed chaotic, rapidly strobing colors. The pixels mostly appeared white but sometimes flashes of other color would strobe in. The pixels would change dozens of times a second instead of once every two seconds. I plugged in another strand of bullet-style 5V WS2811B LEDs and I saw the same chaotic strobing.
These lights are all supposed to be compatible, in the case of the first two strands they are the same type of LEDs. Do you know what could be going wrong here? Are there some refresh rates that cause this problem with some lights? Thanks for any advice. If needed I can take video of this but the difference is so dramatic the description alone may be enough to indicate the cause.
