I changed the slave code and made it simpler. but SSP interrupt seems to be not firing (responding)

#include <16F877a.h>
#use delay(clock=20000000)

#fuses HS,NOWDT,NOPROTECT,NOL ...

Yes, but I am writing to another PIC if you re-look to my code:

What will be the range of addresses in my case ? What are the first and last addresses in my buffer ? How to know it if i am connecti ...

Yes, in the EEPROM there are three bits for addressing, allowing to address up to 8 devices on the i2c bus. But in my case, i have a PIC.

My question in other words is, how to know the register add ...

Ok, thanks but how to specify a register from the master to be written in the slave. Can you give me an example ?

Hi,

I am trying to conduct simple i2c communication between 2 PIC16f877A.

The communication seems to be not working:
