Hi Andy,

I saw STA=1; inside i2c_transmit() function.

I want only to see the interrupt workes. And I wish see the interrupt workes in the LPC. But i'm frustrated. Neither this simple code is working in LPC, but it workes in the simulator.

Ok, I removed STA and STO from my code and tried again. It doesn't work too.

What's my problem ?

void main(void)
{
  P1M1 &= 0xEF;
  P1M1 |= 0x20;
  P1M2 &= 0xDF;
  P1M2 |= 0x10;

  P1 |= 0x10;
  i2c_init(0x00, 0);
  EA=1;
  while(1)
  {
  	i2c_transmit(M24C01);	// send peripherical address
    while(STA);// wait trans.to be completed (device address)
  }
}
