From your example it looks like you placed the device reading
(interrupt read) and writing (set report) into the same read thread. I
thought keeping them separate was a good idea: tight loop reads and
less frequent writes (LCD updates).

Hmm I'll see what I can come up with. The language of all these units is

inherited stuff or how even the functions and procedures manage to get anything
done. I've been programming with Pascal since Turbo Pascal bac
