I am using a 6542 HS-DIO card. I need to generate an output pulse synchronous to the input trigger which I have at PFI0. At PFI0 is a trigger with period 40MHz. Every trigger I need to generate an output pulse at the digital data & control port. I have tried to use dynamic data generation, and to poll for status using a while loop with HS-DIO "Is Done" command inside. This is not fast enough. I think this is because the PCI bus of the PC is part of the loop. However, I do not need it to be part of the loop, I want to configure the 6542 card for HW trigger, and let it run by its own. How can I do that?
