First Light Doesn't Work

[christmasmatt]

This may sound like a really silly question but for all of my props, the first pixel in the line doesn't work.

The data from the first pixel will be pushed to the second, the second to the third and so on.

There is nothing wrong with the pixels themselves, I have tested them.

They look like bullets so shouldn't really be a manufacturing issue (some seeds have blobs of glue where the first pixel is meant to be to cover manufacturing issue), have you got your props setup in xlights with a null pixel? See this thread for how to set it, you would want to check to see if it is set and then remove it.

Null Pixel assignment

Hi can someone please confirm how to assign a null pixel in xlights. I have an Advatek Pixlite 16 controller, and I have read from forums that I need fit the null pixels, at the front on the prop between the controller and first pixel. Also how do you fit null to 5050 LED strip. Thankyou

They're 3-wire, not 4-wire? (Maybe xLights needs the usual upload to controller and rerender.)

Check the port configuration on the controller settings. I'm assuming it has one null pixel. Assuming on the hardware side, not xLights

My seed pixels do it but I think it is just a manufacturing issue

 

[Juddge]

will be a null pixel issue or a incorrect start channel setup in the outputs / visualiser / models

Shoot up screenshots of the Xlights visualiser for that port and also the port in the controller.
