  Subject: [lpc2000] spi in lpc2106



  Hi friends

  i am working in Lpc2106 and facing problem in spi mdule.
  Actualy  i am using spi module in master mode. i checked my code in
  jtag debugger(wiggler in CrossStudio)and found that when writing data
  to the SPDR register then SPif bit in SPSR also sets showing that
  data is transmitted.

  But the problem is that nither data nor clocks in the MOSI & SCK pins.


  If some body can help me i will be very thank ful to him.

  My source code attached
  int main (void){


        IOSET=0x80;
        IODIR=0x00;

        PINSEL0 = 0x00005500;

  //Config over
          init_spi();

          IOSET = MMC_CS; // Chip select High
          MmCardSendByte(0xAA);
          IOCLR = MMC_CS; // Chip select Low

          while (1);
  }

  void init_spi(){
      unsigned char ch;


      IODIR |= MMC_CS; // io direction of mc chip select
      IOSET = MMC_CS; // Chip select High

      SPCCR = 0xfe; // clock counter
      SPCR =  0x20; // spi master mode,

  //   ch = SPDR;// data read

  }

  BYTE MmCardSendByte(BYTE bt)
  {
    BYTE input;
    SPDR =  bt;
    while (!(SPSR & 0x80));
    input = SPDR;

    return input;
  }
