Hi again Dennis, Well I´m just trying to understand how to simulate an analog measurement taken from the USB6001, and then import to a visualization variable. But it is quite difficult for me. It's some years since I use labview in school... so I forgot many things.
I did what you mentioned and errors disappear, but now the program indicates that the buffer is not enough. I dont know where to set the buffer size, and which is the exact size. I just want to extract 5V for example.
The theme of the loop is controlled, it is an issue that will solve later. I just want to see that the output is activated.
The code makes no sense. You try to generate a 0 Hz signal? Then you tell it to use a waveform for timing, then write only a single sample. If you want to generate a single voltage, get rid of the timing function and just wire a constant to the DAQmx Write.
It should be Analog DBL 1Samp like you have now with a scalar connected instead of that waveform as I said. Static voltages do not require the timing function either, as I also said. You can place the DAQmx Write inside a while loop and use a front panel control for the voltage setting. When the loop exits, be sure to write 0 volts before stopping and clearing the task.
