Force of habit or maybe there was a reason I put a pause after serout in a loop. I know that I discovered the hard way that I needed to do that in Python to keep the cpu from working too hard (and a little bit of pause made a huge difference).

But what about PIC's ?

I simply have --
START:
DO STUFF
SEROUT PORTA.0 T2400 (ETC)
PAUSE 200
GOTO START

Actually, I need to reduce it to 50 or so because I have it feeding a PI with a python script that's reading it but what effect does a pause have with a PIC's performance? Is a pause "good practice" or completely unnecessary? -- thanks much
