I have faced some problems while using triggering with 6534. They are listed below. Please provide solution me.
1. ) i was using pattern input with triggering(buffered) in which i am using the example given in library buffered pattern input-triggered.vi
Now i am using port 0 to take input. From line 0 of port 2 i want to generate a pulse which can trigger the operation & start acquisition. For that i am using write to single line.vi . My DPULL is open so bydefault the line will be at low level & by vi i will make it high which will trigger the operation.
In normal condition if we use write to a single line.vi it will write the given status on that line within a fraction of second and abort execution. But when i am usin
g it for trigger in following manner, it did not work.
First i started the VI buffered pattern input-triggered.vi.I have configured the start trigger with leading edge trigger. I have set the time limit properly.Synchronous operation is set at the front panel of vi.
Now if start the write to a single line.vi to give start trigger, nether it triggered the operation,nor it abort execution of single line write vi.When time out occured in triggered vi, then both vis stopped simultaneously. Why this happened?
2.) Similar problem i faced when i wanted to perform the change detection.vi Port 0 is configured for input.Line 1 to 7 are fixed with some status by connecting them to Vcc or GND. I have connected port 0 line 0 with port 2 line 0. So when i change status of line 0 of port 2 change detection should be occured o port 0. i am changing the status of line 0 of port 2 by write to a single line.vi But here i faced same problem as first that it was not writing to port 0 line 0. And bo
th process stopped when time limit occured in change detection vi.
So what can be the problem? Please help me.
