Loads a new LED pattern to play on the currently selected LED channel (selection is made through the pat.channel property).
pat.play(byref pattern as string, patint as pl_pat_int)
Pattern string, can include the following characters:
'-': both LEDs off
'R' or 'r': red LED on
'G' or 'g': green LED on
'B' or 'b': both LEDs on
'~': looped pattern (can reside anywhere in the pattern string)
'*': double-speed pattern (can reside anywhere in the pattern string). You can use this symbol twice to x4 speed. Adding even more '*' will not have any effect.
Defines whether the pat.play method is allowed to interrupt another pattern that is already playing:
0- PL_PAT_NOINT: cannot interrupt
1- PL_PAT_CANINT: can interrupt)
Maximum pattern length is 16 "steps". The on_pat event is generated once the pattern finishes playing. Looped patterns never finish playing and thus the event is never generated for them.
Note that channels 1-4 require you to map LED control lines. See pat.greenmap and pat.redmap properties for details.
