Arduino Micro as RGB to GRB converter for WS2812B/APA106 LED packages.

Former Member
Former Member over 9 years ago

Hi,

I have been playing with an Arduino Uno for a little while just seeing how the code works addressing the individual WS2812B LED packages. I have a general idea about the concept, and will happily modify existing code for fun/experimenting.

However, I have run into a bit of a problem trying to link a strip of ten WS2812B's with another series of ten APA106's. It appears that one or the other expects data in RGB format while the other expects data in GRB format.

Blue is okay, but red on one package displays as green on the other with the same data string. I was wondering if anyone had come across any code which I could run on something like an Arduino Micro which would receive the data in on one pin and reformat it before sending it out on another? I would like to place this between the two groups of packages as a format converter.

Something small like an Arduino Micro would be easily concealed and could run happily off of the 5V provided for the LED packages.

Any help would be appreciated.

Thanks

    Hi Clem, t

    Thanks for the links. Unfortunately the Bit Banging info was a bit over my head. image

    I will keep researching in the Google and Youtube Libraries until I find something that I can Frankenstein together for this purpose.

    Cheers.
