Hi all
I have already posted a help ple on this subject,
Hopefully I may get a bit more help ...
I will try to explain what I am trying to do.
I am using a 12F675, running its internal clock.
What I am trying to get my head around some timing loops,
I am trying to do following...
I need an output to trigger as soon as the pic gets an input, (easy)
But it needs to hold latched for about 20 seconds from the time the input is released.
If an input is applyed to the pic within the 20 seconds the timer needs to reset back to 20 seconds until the input is released. (then carry on as before)
I then need to be able to cancel the 20 second delayed latch by applying a second input
to the pic. (clearing the delay and lifting the latched output)
(A BIT MORE INFO)
The input pulses are actualy toggled inputs,
The input can be anything from 1 second to several mins.
The pic circuit is actualy going to be used in a low power radio link,
and its to control the transmit delay to stop it from chattering.
...................................
I have grasped the basics,
but when it comes to timing loops I am beat.
I have only been into pic programming for just over a year,
and are learning fast.
Half the problem is knowing where to start,
If you possibly could draft out a bit of program code,
I would be greatful.
Cheers
Dave....
