Hi,

I´m trying to setup an interrupt for SPI, but without success.

This is my code:

void SPI_IRQ (void) __attribute__ ((interrupt("IRQ")));

int main (void) 
{
  unsigned n,i,reply;
	IODIR1 	= 0x00FF0000;           /* P1.16..23 defined as Outputs  */

	// setup SCK pin P04
	PINSEL0 &= ~(3<<8);
	PINSEL0 |= 1<<8;
	// setup MISO pin P05
	PINSEL0 &= ~(3<<10);
	PINSEL0 |= 1<<10;
	// setup MOSI pin P06
	PINSEL0 &= ~(3<<12);
	PINSEL0 |= 1<<12;
	// setup SSEL pin P07
	PINSEL0 &= ~(3<<14);
	PINSEL0 |= 1<<14;

	VPBDIV 	= 0x02;					//Set the Clock VBP clock to 30 Mhz
 
	VICVectAddr0 = (unsigned long)SPI_IRQ;
	VICVectCntl0 = 0x20 | VIC_SPI0; // SPI Interrupt 
	VICIntEnable = 1 << VIC_SPI0;   // Enable SPI Interrupt 
	
	
	S0SPCCR 	= 0x00000064;			//Set SPI bit rate at 300Khz
	S0SPCR  	= 0x000000A0;			//set control register Master Mode and
Interrupt enable
	
  	result = write_byte(0x06);

  while (1)/* Loop forever */ 
  {	
  ;		
  }
}

void SPI_IRQ(void)
{
	IOSET1 		= 0x000F0000;           // Turn on LEDs
	S0SPINT		= 1;
	VICVectAddr	= 0x00000000;	
}

If I just dissable the interrupt I can se that the byte is sent.
But if I enable the interrupt nothing happens when I try to send
something. The application just halt. No interrupt is generated...

Can someone please help me?

Thanks 

Peter
