Unfortunately, I do not have a worked example demonstraiting this. However, when you call the adc11_get_times_and_values there are two parameters that are pointers, in Labview you will need to use arrays. The next point is that the array for the values should be:
values array = number of samples requested * number of active channels
The Number of values is the value passed in the get_times_and_values function as the third argument. The number of active channels is set in the function call adc11_set_interval.
Finally the values array, has reading one after the other eg if three channels are used then the array would look similar to this
array 1, 2, 3, 1, 2, 3, 1, 2, 3 ........ etc.
To start with I would recommend that you try this function with just one channel activated. If you are unable to get any response check the ADC11 with Picolog.
Perhaps someone else on the forum can give you a worked example.
