Hope I get a Christmas present, the turkey did not answer my problem.
Made the change as suggested in post under gpt_1 add interrupt to the ISR module.
That was the only change to the .c code.
Compiles ok but will not link. conflict in memory model.
I have tried all options in build properties run time but no change.
If more infon is needed I can supply.
Please help.
