Understanding Null Pixel
« on: October 19, 2017, 08:03:25 AM »
Is a Null Pixel a programming thing or is it a actual physical pixel in the string. How is it done?
Thanks

The purpose of the NULL pixel is to recondition the data signal so that you can reach further distances.  I'm mainly familiar with the Falcon cards which just insert dummy data into the stream so that the NULL pixel grabs a command of 0 and doesn't turn on.  So if you had a string of 100 pixels the board is sending out data for 101 pixels.

You don't.  The controller does like I said.
