Is it possible to use the USB-6509 to detect and read digital changes for 50+ channels. And the changes could be as small as only 2 milliseconds wide?
My first idea was to use the Change Detection feature of the 6509 to trigger a read DIO-event.
The data read could then be used to indicate which IO-port changed.
An alternate solution could be to poll the DIO continuously and detect the changes through software.
Although this would require a lot more processing. What data rates would be possible over USB?
Is this even possible over the USB-interface or do I need a faster interface, like the PCI?
Thanks,
