Re: Need a code example of slave spi-dma for 21262

Hi Pingu,

           The 21262_SPI_Slave example code uses the SPI slave in receive mode. The same code can be modified for transmit operation as below:

void main()
{
*pSPICTL = 0;

interrupt(SIG_SPIH, Transmit_data);

*pSPICTL =  SPIEN | TIMOD1 | WL32;

while(1)
{
  asm("nop;");
}
}

void Transmit_data(int i)
{
*pTXSPI =  source[int_count];
int_count++;

if(int_count >= N)
  *pSPICTL = 0;
}

Regarding the issue seen on the other post, I could see that Mitesh has suggested few things on his last post. It will be good if you can post your follow-up questions on the same post to avoid any duplication efforts.

Hope this helps.

Best Regards,

Jeyanthi
