I use gcc.
It doesn't accept PortC.0 = 1;

In the IO.H (for the chip) there is a section, e.g.


/* DDRB */
#define DDB7	7
#define DDB6	6
#define DDB5	5
#define DDB4	4
#define DDB3	3
#define DDB2	2
#define DDB1	1
#define DDB0	0

I wonder what it is good for?


I would use define if i could figure out how ;-)
