I have a 220 ohm resistor connected to the RB0 pin to the bottom left side of the pushbutton and a jumper wire from Vdd connected to the upper left side of the pushbutton. A 10 kohm resistor from the top right side of the pushbutton to Vss. The LED is connected to Vss and a 470 ohm resistor connected to the RB7 pin. Is the code the same if I use a LED in place of the piezoelectric speaker that was originally used in the code? Also, I would like the pushbutton (RBO) to be my only input and the LED (RB7) to be my only output but when I put in: [b]mov !rb,#$01[/b] (i.e. 00000001) the LED light comes on automatically with or without the pushbutton pressed. This code doesn't seem that complicated but I've run into many problems. I can easily code this in PBASIC for the BS2 but assembly is new to me.
