how to use "Pattern_Input_to_Binary_File_(cont).vi" to read data using DMA?

[fady]

I am a beginner in this area, I have a PCI-6533-DIO-32H digital I/O card and I want to configure it to put the data it gets into memory (DMA) and use some labview program to take data from memory and process it. I found this vi on thw website and I was wondering how can I configre it to do DMA write/read. I am also not clear if this task (DMA read/write) requires using VISA to write an instrument driver or not. Any help or directions will be greatly appreciated. Thanks

Hi,

The default data transfer mode is DMA in LabVIEW. You will not need to configure anything. If you wanted to change it to IRQ, then there would need to be some changes made. Also, doing a DMA transfer does not require the use of VISA to write an instrument driver. This DMA transfer is possible through the driver, and so there is no programming necessary to configure it. I hope this helps, and have a great day!
