Input command

Hi All,

I'm sending a signal to a input on a stamp, its a very short burst of
+voltage (I have a LED hooked up in parallel so I can see the pulse) I'm
using a "input=1 then" in a loop to see it, I have also tried the button
command"

My problem is that some times the program doesn't see the burst of
+voltage, is their a latching type of input command or a hold for one
second to see the voltage ??

Bob

    You have to say 'in(pin) = 1 then......
    If you are inputting to pin 0 then write
    if in0 = 1 then......

    Yes, I am using the correct input (pin)=1 command, I just didn't say it in
    the message.

    Then the next thing is to just set the pin high - don't pulse it. If you
    pulse it, by the time the program getss to the loop the pulse is gone and pin
    = 0.
