time delay on relay release

[temp]

On the T100MD I close and open a relay at a certain frequency as follows:

if pulseperiod(1) < 33000 then
  setio  out1
else
  clrio out1
endif

how do I insert a delay (say 5 seconds) before the relay releases?  I need a certain amount of hysteresis in the circuit.

You can use Out1 to trigger a timer (lets call it T1)

Then before you execute the CLRIO statement, perform a check:

.....
ELSE
   IF TESTIO(T1) = 1
            CLRIO OUT 1
   ENDIF
ENDIF

This way, OUT1 will not be cleared  unless T1 contact closes.
