Hello again
Following my previous post on the above:
I guess 17 is a bit tight for 1.1mS as 17*64uS is 1.088mS, that's why
it seems to work with a larger number, maybe the remote I'm using is
a bit out of specs. By putting a breakpoint at start2 timerL=18 pretty much
everytime.
start2: cpi timerL,17 ;If startbit longer than 1.1ms,
I think I figured out what the var "inttemp" does. (DUHH)
It is simply a counter for timerH, when inttemp overflows, then
timerH is incremented. The var timerL cannot be used for this
purpose as it may get cleared in the decode routine
inc timerL ;Updated every 64us
inc inttemp
brne TIM0_OVF_exit
inc timerH
Regards
John Samperi
