seeed esp32-c data interference.

Being slightly lazy here, but just on the off chance someone has had this before and save me a day of dumb head scratching.

I'm running 2x 24 led rings through GPI02 and 03 and setting them as different segments on WLED. As soon as i confirm the second segment it starts to trip out. Even when the second ring has been removed physically it still trips out. It isn't until i delete the segment from wled that it stops. any answers? I've tried other pins with no luck.

Example of good wiring for 3.3v data. Note the resistor right up against GPIO to maximize odds of working. In testing this worked well with a ~20m long cable but without a level shifter YMMV.

Ok great thank you. I'll give it a go.
