How to use BUTTON command right?

[Tissy]

Hi Gert,

I think this is what you may be after:

' ---------- [ I/O Definition ] ----------
TRISC = %00000001       ' Set PORTC (0-2 input) rest Outputs
PORTB = 0

' ---------- [ System Inputs ] ----------
Switch      Var PORTC.0         ' Momentary Switch on PORTC.0


' ---------- [ System Outputs ] ----------
RedLED      VAR PORTB.1     ' All LEDs connected
                            ' between RC pins and
                            ' ground via resistor

Main:
    If Switch=1 Then                      ' If button is pressed:
        Toggle RedLED                     ' Toggle the LED
        loop: If Switch=1 Then Goto loop  ' Wait until the button is released
    Endif
Goto Main

Is this wht your after try it and lets us know
it uses 1 button to turn led on/off

led1_status var bit
button1 var portb.0
led1 var portb.1
main:
if button1 = 1 then ' if the button is pressed

if led1_status = 1 then ' if its last state was 1

led1_status = 0 ' make it 0
low led1
pause 500 'debounce

else

led1_status = 1 ' the last state was a 0 so now make it a 1
high led1
pause 500 'debounce

endif

endif

Hi,

Thanks to Tissy and Chuck for your examples.

I can conclude that you don't use the BUTTON command when you "read" a switch.
I just thought that it was possible to set up all the parameters with the BUTTON command.

But I think that your examples teach me that using IF - THEN and GOTO or WHILE - WEND gives me much better possibilities.
