#int_ssp not work
PostPosted: Fri Oct 16, 2009 4:44 pm     Reply with quote
Hello All

I have two Pic microcontrollers 18F2550.
I use I2C (One PIC master and one PIC slave).
My problem is the #int_ssp not work.

MASTER:
Code:

#use i2c(master, SDA=PIN_B0, SCL=PIN_B1, address=0x01)
#use rs232(baud=9600, xmit=PIN_C6,rcv=PIN_C7,STREAM=PC)

#INT_SSP
void i2c_isr()
{
 printf("\n\r&&&&&&&&&&& enter master interrupt &&&&&&&&&&&&\n\r");
}


void main ()
{
  enable_interrupts(GLOBAL);
  enable_interrupts(INT_SSP);

for(;;) {      
        i2c_start();
        i2c_write(0x02);
        i2c_write('a');
        i2c_stop();
      }


SLAVE:
Code:

#use i2c(SLAVE, SDA=PIN_B0, SCL=PIN_B1, address=0x02,)
#use rs232(baud=9600, xmit=PIN_C6,rcv=PIN_C7,STREAM=PC)

BYTE  state;
unsigned char i =0;

#int_ssp
void i2c_isr()
{
   printf("\n\r********Enter interrupt************\n\r");
   state = i2c_isr_state();
   printf("++++++++++++State = %x+++++++++++++++++++++++++\n\r",state);

 
}



void main ()
{

enable_interrupts(GLOBAL);
   enable_interrupts(int_ssp);
     
    
   for(;;){ }

}

Look at these threads for sample code for an i2c slave:
