A puzzle: I got stuck at this state - at line 76 there is an empty #define - which won't compile.

Not sure how I managed it or how to cure it....

Any suggestions

Hi Martin

I deleted all your macros and all your code and changed the chip to a PIC, but still this error!
There is a strange thing (for me) What is this panel with Pins in your Program even I deleted all?

This problem is related to the "DC Pin" property on the panel. If you edit this and untick "generate a define for the property" then the problem goes away.

Or if you want a define for this property to be added, click the drop-down next to that checkbox and enter the define name and value.

Hi Steve

Thanks a lot. It solved the compiling problem.

In one of my program I had also this panel and I never understand why there are pins, and for what are this pins? a component?

In the 2D panel or 3D panel there are no components. I deleted all......

Many thanks, I don't think I'd have spotted that - and I'd have starting deleting things and that would surely have been last to go!
