CC2652PSIP: Timer Edge Capture for Counting

Hello Chris,

We may not have an exact example here, but we can try modifying the period example to use edge capture:

(reference the SDK documentation by pressing the "GPTimer Driver" hyperlink) 

GPTimerCC26XX_Handle hTimer;
void timerCallback(GPTimerCC26XX_Handle handle, GPTimerCC26XX_IntMask interruptMask) {
    // interrupt callback code goes here. Minimize processing in interrupt.
}
void taskFxn(uintptr_t a0, uintptr_t a1) {
  GPTimerCC26XX_Params params;
  GPTimerCC26XX_Params_init(&params);
  params.width          = GPT_CONFIG_16BIT;
  params.mode           = GPT_MODE_PERIODIC;
  params.direction      = GPTimerCC26XX_DIRECTION_UP;
  params.debugStallMode = GPTimerCC26XX_DEBUG_STALL_OFF;
  hTimer = GPTimerCC26XX_open(CC2650_GPTIMER0A, &params);
  if(hTimer == NULL) {
    Log_error0("Failed to open GPTimer");
    Task_exit();
  }
  Types_FreqHz  freq;
  BIOS_getCpuFreq(&freq);
  GPTimerCC26XX_Value loadVal = freq.lo / 1000 - 1; //47999
  GPTimerCC26XX_setLoadValue(hTimer, loadVal);
  GPTimerCC26XX_registerInterrupt(hTimer, timerCallback, GPT_INT_TIMEOUT);
  GPTimerCC26XX_start(hTimer);
  while(1) {
    Task_sleep(BIOS_WAIT_FOREVER);
  }
}

Thanks,
Alex F
