How can I solve this?

[Mapo]

Hi everyone,
I have two buttons and would like to change the position of the controls.
In simple terms:
Dim Button1 as byte = 0
Dim Button2 as byte = 1
If portb.button2 = 0 Then
....
The compiler writes this error:
*** Invalid Cast for this type of variable! ***

How can I fix this?

Hi,
Dim Button1 as bit = 0
Dim Button2 as bit = 1
If button2 = 0 Then

Hi,
Or did you want to do something like this?
 Symbol Button2 = PortB.1
 if button2 = 1 then

Example: key 1 moves forward and key 2 moves backward.
Now, using a switch, I'd like the ability to swap key 1 with key 2.
Of course, I'm not limited to just two keys.

Hi,
If I understand correctly

if Switch = left
Button 1 = forwards
Button 2 = backwards

if Switch = Right
Button 1 = backwards
Button 2 = forwards

If this is the case I think it would be best to have a couple of subroutines or procedures, one for left and one for right which returns a temporary variable for the direction.

Regards,
Bob

Dim Button1 As Pin
Dim Button2 As Pin
Symbol Switch = PORTC.0
 
Main:
    If Switch = 0 Then
        Button1 = PORTB.0
        Button2 = PORTB.1 
    Else
        Button1 = PORTB.1
        Button2 = PORTB.0
    EndIf
End

Make sure you have the correct port direction set i.e. I/O

I am sure you have a reason for wanting to do that, if it is an internal switch for factory customisation so it is a set once and leave then it would be fine. However, if it is an external switch I am not sure that is a particularly practical solution I think it would get annoying in use as you press the button for one direction but it goes the other way due to the switch position being changed.

Of course, I'm not limited to just two keys.

If it was just the two then as you are using switch anyway I would have suggested using a DTDT switch to swap them instead of remapping them in code, but that may not work so well if you are swapping more than two inputs.
