Can I Control the Pulse offset using the Counter Out?

Question

Hello Everyone.
I am trying to generate the Pulse as below;
I have seen and understood an example to generate a pulse waveform "GenDigPulseTrain_Continuous".
However, I can not control the offset of the pulse train.
Although the function gives me "initial delay(The amount of time in seconds to wait before generating the first pulse)",
I can not shift "t_dead" cycle.
/*01.Frequency Control*/
 // The units to use to define pulse frequency.
  m_pTaskWrite->COChannels.CreatePulseChannelFrequ​ency(vecstrings[0]/*LPCTSTR counter*/,
   "PWM_C0_CH_HIGH"/*LPCTSTR nameToAssignChannel*/,
   DAQmxCOPulseFrequencyUnitsHertz,
   DAQmxCOPulseIdleStateHigh,
   dDeadTime, 
   m_nFncFrequency/*frequency*/,
   prDuty.second/*dutyCycle*/);
  // The units to use to define pulse frequency.
   m_pTaskWrite->COChannels.CreatePulseChannelFreque​ncy(vecstrings[1]/*LPCTSTR counter*/,
    "PWM_C0_CH_LOW"/*LPCTSTR nameToAssignChannel*/,
    DAQmxCOPulseFrequencyUnitsHertz,
    DAQmxCOPulseIdleStateLow,
    dDeadTime/**2 + (prDuty.second *dCycleTime)*/, 
    m_nFncFrequency/*frequency*/,
    prDuty.second/*dutyCycle*/);
Please let me know how I solve this problem.
Thank you

Dear Zl,
Counting pulses is much easier with the FP-QUAD-510 or FP-CTR-500, but can be done with the FP-AI-110.  You can't directly count the pulses with a FP-AI-110, but you can do it in software. Bring in the data by doing a normal read. Then, using shift registers, if the previous voltage is less than .8V (low) and the current voltage is more than 2.5 (high), increase the pulse count. I have attached a program that shows what to do with the data once you bring it in. I took the data from an array outside the while loop, but your data will be brought in one point at a time inside the while loop. One thing to take note of, since Fieldpoint brings in data at 1 kS/s, this will only work with pulses slower than 500 Hz. The farther the duty cycle is away from 50% duty cycle, the slower the signal must be in order to catch the pulses correctly. Please let me know if you have any questions. Have a great day!
Sincerely,
Marni
