dear
following is my code
i am not getting spi clock..i tried sample code too..here i am interfacing ads1174 to tms320c5505..
void spiInit()
{
Uint16 temp;
temp = SPICCR;
SPICCR = temp & 0xBFFF;
SPICDR = 0x0004;
SPICCR =~(1<<15); // reset the SPI_CLK
// SPICDR = 0x0031; // SPI_CLK = (SPI_IP FREQ/(CLKDIV+1))=120MHz/11+1=7.692MHz
SPIDCR1=0x0000;
SPICMD1 = 0x000F; // 16 character, FLEN+1, no interrupts
SPICMD2 = 0x00F1; // CLEN, type of transaction,read,30bits
SPICCR =(1<<15); // Enable the SPI_CLK*/
}
int main(void)
{
ProgramPLL_100MHz();
SYS_PCGCR1=0;
SYS_PCGCR2=0;
SYS_EXBUSSEL =0x3000;
// SYS_EXBUSSEL = 0x1A00; //spi mode1+gpio
i=0;j=0;
spi_reset();
spiInit();
FrameLength_setup(3);
adcInit();
while(get_spi_busy_status());
while(1)
{
while(!((SPISTAT1 & 3) ^ 2)& 2); //temporary use. most likely will need to consider the other reserved
//bits to not interfere with the correctness of the result.
SPIDAT12_clear();
SPICMD2 = SPICMD2_READ;
adcOutCh5[i]=(SPIDAT2 & 0x00FF);
adcOutCh5[i]=adcOutCh5[i]<<8+SPIDAT1;
printf("%d\n",adcOutCh5[i]);
i=i+1;
// SPI_dataSend ('k', 8);
}
*/
}
