From ASCII to binary (SPI config)

CitRam — Mon, 27 Jan 2014 06:37:35 GMT

Hello!

I'm learning to write code for FRDM KE02Z. I woluld like send binary word via SPI, for example write binary word like 11110111 not ASCII characters. In my task eighth bit must be parity bit. I already tried use parity bit set in Component Inspector/SPI0/Atribute Set List, but KE02 doesen't support SPI pairty bit.

Could you advice me how should I change the subroutine string uint8_t OutData[BLOCK_SIZE] = "FF", for ability writing binary word not ASCII characters.

Below my code

#define BLOCK_SIZE 4


uint8_t f;
uint8_t OutData[BLOCK_SIZE] = "FF";
uint8_t InpData[BLOCK_SIZE];
volatile LDD_SPIMASTER_TError ComError = 0U;
LDD_TError Error;
LDD_TDeviceData *MySPIPtr;


/* User includes (#include below this line is not maintained by Processor Expert) */


/*lint -save  -e970 Disable MISRA rule (6.3) checking. */
int main(void)
/*lint -restore Enable MISRA rule (6.3) checking. */
{
  /* Write your local variable definition here */


  /*** Processor Expert internal initialization. DON'T REMOVE THIS CODE!!! ***/
  PE_low_level_init();
  /*** End of Processor Expert internal initialization.                    ***/
  
  
  
  MySPIPtr = SM1_Init(NULL);                               /* Initialization of SM1 component */
  //SM1_SelectConfiguration(MySPIPtr, 1U, 1U);               /* Select chip select 1 and attribute set 1 */
  while(1){
  Error = SM1_ReceiveBlock(MySPIPtr, InpData, BLOCK_SIZE); 
  //f=atof(OutData);/* Request data block reception */
  Error = SM1_SendBlock(MySPIPtr, OutData, BLOCK_SIZE);    /* Start transmission/reception */
  while (!SM1_GetBlockReceivedStatus(MySPIPtr)) {          /* Wait until data block is transmitted/received */
  SM1_Main(MySPIPtr);
   }
  }
  /* Write your code here */
  /* For example: for(;;) { } */

  #endif
