PIC to WS2812B / WS2811 IC

I am also going to be playing with these, but won't have it until the end of the week. Hopefully we can make these things work! Link to my thread

Somewhere here, I looked... I cannot find it... are some code examples for timing execution of code segments; they might be of value to you. Even without, it should be reasonably straightforward to initialize/ start a timer and read the value after to determine exact timing of the If [] Then statements. I have not used the WS LED strings, but I think you don't need help with what is required to do so - only to determine how long what you have takes.

My understanding of such things is limited, but I can "grok" the frustration of timing routines that are written in Basic, but executed in Assembler. I can think of no simpler way than to have your program do it for you.

One last ting... Have you any numbers for amperage required to run a string of these things? I suspect it could run into the 10's of amps for applications like Christmas lights?

Each chip is current limited to ~19mA per channel... and there is 3 channels...
