Thanks for all the feedback on my 3 button
to 2 input
I was thinking about John Payson's
approach of botton 3 shorting 1 and 2, but I wanted to
make this interrupt driven since it will be a low use input. That would have
to be scanned...
besides if I take anymore advice from
John on this project
I'm going to have to put his name on the
The dual diode approach using RB6 and
RB7, with a common
cathode SOT-23 device only adds one
small part and with it INT
driven, it will be very hard to hit both
buttons at exactly the same time.
Once I get an INT and read the pins I
will not re enable INTs until I read
11 on the port again for a DEBOUCE
length of time....etc.....
I'm keeping in mind Dave Duley's 1 pin
RC approach though!
Thanks again all.
