Hi All,

I have developped some code. Too complicated and large to paste here but somehow when I execute a particular piece of code on that block when node red is running it stops the Revolution Pi output (analog) block from updating??

All the other block keep functioning as normal, no errors , nothing that indicates there is a problem apart from the Revpi output not functioning anymore.

All the input blocks from node red still function and everything else also?

How do I debug this when nothing else happens? Any ideas ?

Thank you in advance!

Poor choice of word for block I meant to say node of course.
