Hello,

I have started to implement the DCL library, but I get an error with the PI-structure. I have just opened the file for the first time ...

Just rename "PI" to something else solves the prob. for now. But that shouldn't be the "normal" way.!?

Has anyone hints?

Thanks!

Maybe name "PI" is already reserved for smth? It's possible, that you have "#define PI 3.1416" somwhere in your headers. So you get "typedef volatile struct {...} 3.1416" after preprocessing.

Perfect! This approach solved the problem! I just did not get this idea yesterday. Many Thanks!

As previously stated, the error is because many people #define PI in their code for the mathematical constant. A new version of DCL (v2.1) will release in C2000Ware on 9/22 which removes this conflict.

Regards,

Richard
