#158172 - Make your mind up!
Responding to: ???'s previous message
In your original post, you said:
how can I regularly monitor these changing inputs at the P0

Then you said:
the problem is not with regular monitoring
http://www.8052.com/forum/read.phtml?id=158169


So why did you specifically ask how to do regular monitoring?!

Of course, if you want to poll for changes - whether using a timer or otherwise - then your polling frequency has to be sufficiently high to guarantee that it will see all changes.

And, as we're talking keypads, you have considered contact bounce, haven't you...?
