Hi Steve,
 
I was just trying to to the continuous digital waveform writing with my NI 9476 card with internal clock, but from looking through the examples delivered with Labview I couldn't really 100% determine if this card can do this.  The specification says
| Timing | 
Hardware | 
| Max Clock Rate | 
2 kHz | 
And the example shipped with labview called:
Cont write Dig Port Int Clk does not indicate to support the NI 9476.
Does this mean I cannot send digital waveforms to all 32 outputs of my card based on hardware timing?
 
Thanks & regards,
 
Lieven
