Hi, list. I got a new laptop the other day and installed the latest MPLab (v8.40) and transferred a project known to compile under 8.30 w/o problems. It (8.40) complained about missing declarations, in particular the ones below. #define BKBUG_OFF 0xFF7F #define BKBUG_ON 0xFFFF #define COE_OFF 0xFFBF #define COE_ON 0xFFFF Now I see they are not in the p24hj128gp210.h file under 8.40 but are present in 8.30. Can somebody please explain to me: * Is this intentional * if so, why, * if so, how can I find out what changes are/what to do with the _FICD(...) * how was I supposed to know about it, other than at the moment I attempted to compile?
