I2C slave not work

[victor pasilla]

i am trying to communicate 2 pic using the I2C bus,

master generate sda and sdl signals, but the slave not responds,

this is the code for the master
....
..
#use I2C(master,sda=PIN_B0, scl=PIN_B1))
.....
.....
while (TRUE){
i2c_start();
if ( i2c_write(0xa1)==0){
resultadoADC[0] = i2c_read();
resultadoADC[1] = i2c_read();
}
i2c_stop();
delay_ms(100);
}
....
....


this is the code for the slave

...
...

#use I2C(slave,address=0xa0,sda=PIN_B0, scl=PIN_B1))

int8 resultadoADC[2];
int16 lectura;


#INT_SSP
void ssp_interupt ()
{
BYTE state;

state = i2c_isr_state();

if(state == 0x80) //Master is requesting data
{
output_toggle(pin_B5); //flag
resultadoADC[0]=make8(lectura,0);
resultadoADC[1]=make8(lectura,1);
i2c_write(resultadoADC[0]);
i2c_write(resultadoADC[1]);

}
}
void main (void){

enable_interrupts(GLOBAL);
enable_interrupts(INT_SSP);


i2c_SlaveAddr(0xa0);

setup_adc( ADC_CLOCK_INTERNAL );
setup_adc( AN0);
set_adc_channel(0);
output_low(pin_B5);
while (TRUE){
lectura = read_adc();
output_toggle(pin_B4); // flag

}

}

can you helpme please
