NOOB in need of help

Sounds good.

How do you make it do one thing when the button is pressed and another when it is not? Like while pressed make a motor run and then stop when not pressed without it being a seprate button?

Thanks for the help

main:

Pause 200

if portb.0 = 1 then gosub pressed0

if portb.1 = 1 then gosub pressed1

if portb.2 = 1 then gosub pressed2

if portb.3 = 1 then gosub pressed3

goto main

pressed0:
toggle portb.4
return

pressed1:
toggle portb.5
return

pressed2:
toggle portb.6
return

pressed3:
toggle portb.7
return

end

Try this way it should do what you need.

See TOGGLE command on manual.

Your posted code should do that.???

Dave, let him discover the Toggle instruction.

The toggle wasn't waht I was looking for. I did try it. When you hold down the button and the toggle was going - on/off/on/off etc.....

Thanks for all the help. I am sure I will be posting more questions as I move forward.

Thanks again -

Hi Keith,
Looks like a classic IF THEN ELSE to me.

TRISB = %00001111    ' 4 upper as outputs 4 lower as inputs
IF  PortB.0 = 1 THEN ' if true then goto next statement
PortB.4 = 1          ' turn on this port 
ELSE                 ' goes to here if false
PortB.4 = 0          ' Turns this port off
ENDIF                ' ends the if then test for true / false and allows code to continue

make sure to use resistors pulling down if you close switches to activate or pulling up if you open switches to activate.

Not sure at all but...

        TRISB=%00001111
        PORTB=0

Loop:
        PORTB=(PORTB<<4)
        PAUSE 200
        GOTO Loop
