This program is for a Pic16f877a (slave) who communicates with another pic16f877a (master), writed in Mikrobasic.

Code:

program slave 

sub procedure interrupt 
if PIR1.SSPIF = 1 then 
PORTB=%00000000 
delay_ms(2000) 
PIR1.SSPIF=0 
end if 
End sub 

main: 
     trisc=$ff                      
     trisb=0                        

     adcon1=0                      
     sspcon=%00110110              
                                  
                                  
     sspadd=$A2                
     PIE1.SSPIE=1                
     PIR1.SSPIF=0                
                                
     intcon =192                  


     while true 
     Portb=%11111111 
     wend 

end.

My question is of this works, and when I write I2C_rd() in the interrupt proces, can read the data of the master?

That code makes no sense. Find an example that works and work from that.

Mike.
