Measuring pulse lengths
Archiver
Posts: 46,084
Hi all,
I would like to know how to measure low pulses for lengths of 0.2,
0.5, and 0.8 s. I looked at the PULSIN command and immediately ran
into a problem. I have a BS2 and BS2SX. The limits for maximum pulse
with according to the manual are 131.07 ms and 52.428 ms
respectively. Thus, I would like know if there are any other ways of
measuring pulses. As always, any input would be appreciated.
Sincerely,
RP

you the difference between .2, .5, and .8 then you could use a if or while
statement with a pause and a for next this is very rough but the idea is
here. now if your pause is set correctly you will get readings of 2, 5, or 8
with debug
looking:
if pin 1 = 1 then timing
goto looking
timing:
for i = 1 to 10
pause 100 'this is a 100ms pause it will need to be shorter to give the
count you need
if pin 1 = 0 then reading
next i
goto overflow
reading:
debug ? i
goto looking
overflow:
debug ? "too much time
goto looking
