Darrel, thanks. before your instant interrups tools never I was experimenting interrupts.

I have clear idea the hserin/hserout sustitution, but I ignored what's the procedure (concretly) for incress the speed.

I havew the display working now, but I need to find de solution for the slow scan.

The question is How incress the speed with the preescaler 1:1 now?

what's the value for load?

Thanks and regards
