Memory Allocation with DAQPAD 6070e

[Manuj]

Hi ,

I want to allocate a specified amount of memory in either my DAQPAD 6070e or on my computer which i can then refer later on.I tried using the VISA MEMORY \ALLOCATION function but unfortunately it cannot see my firewire connected DAQPAD(this I beleive is because DAQPAD runs on traditional DAQ drivers). Unfortunately I have not been able to find any other way of doing it.

Can anyone please tell me how i should approach this problem ?

Hi Manuj,

Thanks for your post.

In order to allocate memory for a DAQPad 6070e aquisition/generation you must use the 'AI Config.vi' or the 'AO Config.vi'. These VIs have an input that allows you to specify the size of your buffer (allocated memory for that acquisition/generation) as a number of data points. With this information LabVIEW will handle the memory allocation for you and create the buffer automatically.

Most memory allocation in LabVIEW is handled automatically for you. If the allocation you are referring to does not concern AI/AO buffers, then please let me know. I will be glad to help.

A little more information about what this memory would be used for (data type), and the context in which it will be used would be very helpful indeed.

Thanks,
