MMMM..This works Ok on the AVSIM51 again...but I just Can't put it to work in real.

When I load another type of program (that only uses outputs to ports) everithing works ok, but when I try to get imputs from the ports, I just Can't read them......

May be this is because I'm putting only a pushh button to GND. Tonight I will try to use a 10K pull up resistor connected to Vcc I order to see if this works.



Thanks!
