Hi mukadder,

yes I did sort it out, the code below works.

Regards.

Herbert Larbie



#include"targets\LPC22xx.h"
void Initialize(void);
// Macro Definitions
#define SPIF (1<<7)
#define SPI0_SEL        0x00000080
#define SPI0_MSTR       0x00000020
#define DATA 0xC1
// MAIN
int main()
{
Initialize();
// Do forever
while(1)
{
// Write data out
S0SPDR=DATA;
// Wait for transfer to be completed
while(!(S0SPSR & SPIF)){}
}
}
// System Initialization
void Initialize()
{
     S0SPCR = 0x00;
     PINSEL0 &= 0xFFFF00FF;
     PINSEL0 |= 0x00005500;
     IO0DIR = SPI0_SEL;
     IO0SET = SPI0_SEL;
     S0SPCCR = 0x08; // also used 0x20
     S0SPCR = SPI0_MSTR;
   }
