Hi,
the switch is actual for a maximum of 10 possibilities decisions written. For a project I need 12 decisions. If you change it, may be to do it for 16 decisions to have some on spare.


Jorg

There are other options.

1) Split over two (or more) switch statements.
2) Use a lookup table.
3) Use a calculation (if possible)

Give us some more details of your use case - and I'll try and provide an example.

Hi

As Martin suggests above, I use "switch" statements one after each other. First has options for up to 10, then the next 11 to 20.

Regards

Hello!
Workarounds are present. But it is easier programming with one variable for the decision. You see one oled screen with 12 possibles inputs you can choose. There are other screens where you can choose 12 inputs again. The program must know, where you are actual standing on the screen. To split into 2 varables is more complecated.

Hi Jorg

You can use the same variable in the switch.
You can also create 2 switch witch 6 position just choose the nummber.
it also has the advantage that the icon is not so wide

switch with 20 position

switch(.x) 0..5 - first 6 options
switch(.x) 6..11 next 6 options

What happens for each option? For example if you set a variable to a value then a lookup table would be ideal.

For example say you set an led to a colour on each option then:

colour = lookup[.switch_value]

If things are more involved (for example some action) then create a macro for each action and use a lookup table of function pointers

In a C block;

FCV_LOOKUP[0] = FCM_Action0;
..
FCV_LOOKUP[11] = FCM_Action11;

Then use a line of C to run the action depending on a variable..

Stefan types fast!

It depends how many options you have - 12 would be fine in two switches. Lots - I'd look at other routes - very large macros make for unreadable (and unmaintainable) code..

Hi ,
I thought, that the numbers are fix in the switch. To change them was a good solution for me.
Thanks to all.

Hi Martin

this looks quite interesting,

could you please explain this with an example code, when you have free time

Thank you

Function pointers is an interesting option, but I don't think Flowcode would simulate this functionality.
