#116776 - Beware! Responding to: ???'s previous message |
See Jez's post about applying slowly-varying analogue signals to digital inputs:
http://www.8052.com/forum/read.phtml?id=116747 Which is pretty much what I was getting at in my original post: I said: ]You can connect a variable voltage to a digital input - it will give a '1' when the voltage is in the guaranteed '1' range, a '0' when the voltage is in the guaranteed '0' range, and something indeterminate when it's in between!
