repsonse to #14 post and #4 requirement
'I'm doing a road test of the PAN1780 eval kit for Element14 and one of the things I wanted to showcase its BT capabilities was doing some light shows with neopixels.'
'I can always do something else instead . . . '
Sometimes just taking a bit of time off, asking the right questions, then overturning that one last stone enables one to find the treasure!
'doing something else' seemed like a load of extra work, and besides who doesn't like bright colored moving lights as a showcase demo to spark a conversation!!
Glad your persistence located the tid-bit of needed info to resolve. . . .
Anyway, thanks again @Robin and @MaBe for the support :)
