Subject: [lpc2000] LPC 2144 I2C Slave

I have a problem with i2c slave because I not have the correct inizialize
procedure.

I have used this procedure:

_BOOL init_i2c_0(void)
{
I2CSlaveState = I2C_IDLE;
I2CS_ReadLength = 0;
I2CS_RdIndex = 0;

//--- set pins ---
MEMMAP = 0x2;

IODIR0 = 0xF0;
IOSET0 = 0xF0;
PINSEL0 = 0x50;

//--- set i2c pll ---
I2C0SCLL = 0xD;
I2C0SCLH = 0xC;

//--- set i2c slave ---
I2C0ADR = 0x20 << 1;

//--- clear flags ---
I2C0CONCLR = I2CONCLR_AAC | I2CONCLR_SIC | I2CONCLR_STAC | I2CONCLR_I2ENC;

//--- set flags ---
//I2C0CONSET = I2CONSET_AA;

//--- Install interrupt handler ---
if ( install_irq( I2C0_INT, (void *)I2C_0_SlaveHandler ) == FALSE )
{
return FALSE;
}

I2C0CONSET = I2CONSET_I2EN | I2CONSET_AA ;
return TRUE;
}

I think this is incorrect because the interrupt is not activated.

Please help me....thaks all.
