16F886.h

[KevinKevin]

hello all.

I have some problem reaching int_RB with 16F886. I took a look to the 16F886.h and compared it to the 16F876A.h , those 2 pics are nearly the same )

i change in 16F886.h line :
#define INT_RB 0x1FF0B08

to :

#define INT_RB 0xFF0B08

after this the int _RB works.

but i have seen this under :

#define INT_RB0 0x010B08
#define INT_RB1 0x020B08
#define INT_RB2 0x040B08
#define INT_RB3 0x080B08
#define INT_RB4 0x100B08
#define INT_RB5 0x200B08
#define INT_RB6 0x400B08
#define INT_RB7 0x800B08

and after checking 16F886 datasheets , this pic have single INT on all of theses PINS

so i tried something like this :

#int_RB4
void RB_isr4(void)
{

printf(" Inside RB4 \r\n");
}

enable_interrupts(INT_RB4);

but #int_RB4 is an unknown preprocessor directive.

Anbody solve this problem ?
Thank you.

Which compiler version are you using?

[KevinKevin]

Sorry

4.032

WELL i tried to replace the int_rb HexValue with hexvalue_of_rb_X

exemple :

#define INT_RB 0x200B08 // this value is #define INT_RB5 0x200B08

and the PIC only reach int_rb on rb5 pin change.

On the 16F887 you have the same problem.
I haved asked ccs about is but they say it isnt supported by the ccs compiler, i think thats wrong.
The Datasheet clearly saves that it support interrup by pin.

Hi all,

Take care migrating any code to the 16F886 or 887.
The current testing of these devices with CCS functions appears to be minimal and there are many changes between say the 876 and the 886.

I have spent many hours with the assistance of PCM Programmer attempting to get the i2c module working as a slave but it just doesn't at the moment.

I guess we will have to give CCS time to complete their testing.

Cheers

Mark
