0100,0100,0100Times New RomanHello,
I expect this has probably been discused before.
I am after ideas/code snippet really, my requirement is a fairly efficient
keypad routine (I have seen a few very long ones), which is NOT interrupt
driven. My own bit of software will decide at what times it is appropriate to
scan the keypad. My own software will have multiplexed display the time
period between outputting new display data may be used for keypad
debounced, so not worried about debounce, my bit of software will sort that
aspect out.
Really after ideas for subroutine that gets key value from a 4*4 keypad. (I
will sort debounce and when to scan).
Many thanks for any help that you give.
Cheers
Andrew Farrar
