Hi you all!
solved my LCD flashing problem with your help: donīt need to clear the display every second but used the "Dec5" command. has zeros in front instead but works fine for me.

New problem: Wanna read the status of 2 bcd-rotary switches with digits from 0 to 9 making a variable from 00 to 99 ( 10 to 99 would do ....) for a digital overrev switch in an electronic ignition.

But I donīt have any clues how to tell my favorite 16F628A to read the two switches ......

I couldnīt use RB0 because I need this to count the frequency.

so letīs assume I got 8 Input ports........

oh yes: and I need the external crystal too, so RA6 & RA7 are in use...


PLEASE Help!
