Reset dashboard values

Can you confirm the payload to the parse function always contains 20 values in the correct order

for the most part unless there is a voltage foible, yes because my 'master' arduino forces the order by sequential polling for the other boards...

but that voltage foible is super rare (and i think due to funky PC USB dock, which won't be used in my final project implementation anyway)

Give this a try I think it meets your needs
