Swapping pins for OneWire

G’day,

For some reason my OneWire failed due to the zapped Tiva output pin. After a rewire to another pin and a sketch redefinition it’s working again. This got me thinking that a good fault finding process would be to allow the customer to be able to flip to another predefined pin without flashing a new sketch. E.g during setup() if a push button is held depressed Pin X is used for the OneWire, otherwise Pin Y.

Now for my problem.

After moving  DS18B20  ds(PIN_OW); into the setup() area’ I get the justifiable error

 'ds' was not declared in this scope

Original code

    #include "TM4C_DS18B20.h"

   DS18B20  ds(PIN_OW);  

New Code

    #include "TM4C_DS18B20.h"

  setup()

       DS18B20  ds(PIN_OW);  

Is there a workaround solution for this.
