Case

Hello to all,

Can somebody give me an example of as using the instruction CASE?.

Thank you

Code:

---

select case Avar
    Case 1
        ' blah blah blah
    Case 2
        ' ZZZzzzzZZZZ
    Case 3
        ' Swing la baquaisse dans le fond d'la boite a bois
    Case NothingWork
        ' Read PBP manual... everything is explain black on white
    END SELECT

---

Leonardo,
Here is a file that uses the SELECT CASE. It is a templete for decoding and then acting on different buttons from a 16 key pad. I use it as an "INCLUDE" to add the routines to the project. Only a couple of CASEs have any meaningful actions in them at this point. Hope it helps.

Select case dtmf ' dtmf is the variable that I am comparing the cases to
case "1" 'this says if dtmf = "1" then
portc = %10010111 'do this
case "2"
portc = %10011001
case "3"
portc = %10011011
case "4"
portc = %10011101
case "5"
portc = %10011111
case "6"
portc = %10100001
case "7"
portc = %10100011
case "8"
portc = %10100101
case "9"
portc = %10100111
case "0"
portc = %10101001
end select ' gets you out of the case statement like endif

This is the general gist of it. I too just learned how this thing works.

Hello,

Thank you to all for their answers, I will make the tests and then I inform them.

Hello,

Can you publish the circuit please?

Leonard,
I am using a basic 16-key keypad, which can be bought surplus on the cheap (BG Micro, All Electronics Corp are a couple places that carry some).

Here is a link that has info on setting up a keypad matrix. The matrix size can be adjusted as required for your application:

Or do a google search (that's how I found the link).
