Delay function on CC1110

Emanuele,

The SimpliciTI code (http://focus.ti.com/docs/toolsw/folders/print/simpliciti.html) has some routines to put in a software delay that might be helpful.  Here's the code for the CC1110 radio:

bsp_board_defs.h:
...
#elif MRFI_CC1110
  #define __bsp_CLOCK_MHZ__         13  /* MHz uses default CLKCON.TICKSPD and CLKCON.CLOCKSPD */
...

bsp.h:

#define BSP_CLOCK_MHZ   __bsp_CLOCK_MHZ__

bsp_board.c:

...
* =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
 *   BSP (Board Support Package)
 *   Target : Texas Instruments CC1110EM/CC2510EM
 *   Top-level board code file.
 * =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
 */
...
void BSP_InitBoard(void)
{
#if defined(SW_TIMER)
#define MHZ_CLOCKS_PER_USEC      BSP_CLOCK_MHZ
#define MHZ_CLOCKS_PER_ITERATION 35

  sIterationsPerUsec = (uint8_t)(((MHZ_CLOCKS_PER_USEC)/(MHZ_CLOCKS_PER_ITERATION))+.5);

  if (!sIterationsPerUsec)
  {
    sIterationsPerUsec = 1;
  }
#endif   /* SW_TIMER */
}
...
void BSP_Delay(uint16_t usec)
#if !defined(SW_TIMER)
...
#else   /* !SW_TIMER */
{
  /* Declared 'volatile' in case User optimizes for speed. This will
   * prevent the optimizer from eliminating the loop completely. But
   * it also generates more code...
   */
  volatile uint16_t repeatCount = sIterationsPerUsec*usec;

  while (repeatCount--) ;

  return;
}

I hope this gets you started.
