digital start ref trigger for analog input with another task (DaqmxBase)

[Novatrex]

Hello,

I am using the C API of Daqmx Base with a 6212 USB.

I can successfully create analog input task with a digital start ref trigger.

I can successfully create a counter output or a analog output.

Once the task is created I loop to do the following:

Start AI task – read AI data – Stop AI task

By doing so I can kind of reproduce the Digital Edge Reference Trigger, except that I do not have pre-trigger samples.

Anyway this works great. The problem arises when I create a counter task (or even an analog OUTPUT task). If I create another task the (Start AI task – read AI data – Stop AI task) loop will work at the first occurrence, but at the second I have a nasty error on the start task.

Does anyone encounter this kind of error? Were you able to solve it?

Hi Novatrex,

Can you elaborate on the details of the error, do you have a specific error code and mesage? If so, you could you paste them here or give a screenshot showing the error. Also it may be beneficial if you were able to attach a copy of your code so that I can take a look at it.

Best Regards,
