Device Header File

[Enquirer]

Hi all,
I am a newbie to CCS compiler. I am trying to setup the device header file to point to the specific address and it's not working for me. see example below

e.g for a PIC18F452 CCP1CON

#define CCP1CON (*(volatile unsigned char *)0x0FBD)

I don't want to use the setup_ccp1(CCP_PWM) function as it doesn't give me much info.

Just use the #byte declaration:

#BYTE CCP1CON=0x0FBD

Your pointer declaraion, ought to be possible to make work, probably with:

#define CCP1CON (*(int8 *)(0x0FBD))

However the byte declaration is easier, especially since it also allows #bit declarations as well. It is the volatile keyword, that will prevent it working.

Best Wishes

I like these:

#pragma BYTE T0CON = getenv("SFR:T0CON")
#pragma BIT INT0IF = getenv("BIT:INT0IF")

But maybe they're only in V4 ?
