Erratic random flickering about espixelstick

[sticilface]

What CPU speed have you set 80Mhz or 160Mhz ?

I've set the cpu to 80Mhz.

Are you using the ESPixelStick boards? If not, what's your connection like between the ESP-01 and first pixel? Any line buffers or resistors? Also, how long is the connection? As for your wireless network, are your E1.31 sources (xLights and FPP) hard-wired or wireless? They need to be wired, and make sure only one is transmitting at time (I've been bitten by this many times with Vixen running idle). Are you using multicast or unicast?

Good call @sticilface. You'll want to set the CPU to 160MHz as well.

Nae worries. Like to help when i can! not often... but sometimes!

• I'm not using the ESPixelStick board. Not sure I understand your question but the dataline of the ws2812b is directly connected to GPIO2 of the esp01e. No buffers or resistors. I've controlled the strip before using the same setup but different software and never had any issues with flickering.

• FPP is hardwired and xLights is wireless.

The strange this is like I said that when the transmission of data stops the string can perfectly well hold it's color without flicker.

I'll see if it helps when I flash with cpu set to 160Mhz.

Thanks for the lightning fast support!

@sticilface 160Mhz totally did the trick! Thank you. Just curious what causes the flickering when running on 80Mhz?

I'm just 2 days into this so it's like seeing magic :)
