,
if she is not using the port P1.0 and P1.1 then there is no need to put pull up to these port pins. have you looked at her code. she is making all the port pins zero when p3.2 goes low. and any pin high after the key press is malfunction. think what happens if she measures all the port pins before she presses the key, p1.1 and p1.2 can show amazing values. when she makes all the pins zero, all will show low though. Why P1.2? :) Also she must check all the 8 port pin, not only P1.0 and P1.1 and thats all... For P1.0 and P1.1: That is why I said use LEDs. Then there is no problem of Pull up. See the above link. |
