Dear friends,
Somebody has a good example of capacitive touch button for the 16f887 in pbp.
in advance thankful,
vicente.

Hi, Dear Friend,
may be a look here could be useful for You :

Now, I do not remember any '887 programs about " Button touch " had been posted here ...
may be some pointers here : http://www.picbasic.co.uk/forum/show...1611#post71611
try the SEARCH function of the forum to be sure ...

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!

F887 will do it. In fact every chip with ADC can do it with some effort.
At www.microchip.com/mtouch there are alot of app. notes and informations. Look for the more recent files.
They have theory of the various phases of the touch evolution.
First there was the charge/discharge with a loop through the micro, then the S-R Flip flop which I recall the F887 has inside, then the ADC use etc.
Of course it is a lot easier with a dedicated module for the the touch senors.
