Changing buffer size of during Double Buffered Pattern Generation PCI6534

[Engineering Services]

Hey guys,
I am trying to change the size of the circular buffer during double buffered pattern generation on a PCI6534. I can do it right now by constantly re-configuring the ports, but I think there must be an easier way. I have already tried modifying the size using the transfer method and have tried calling the blockout mehod with a different size(while running) to no avail.
Thanks in advance
Dave

Dave,

Greetings. Why do you want to change the size of your buffer during your continuous pattern generation? Reconfiguring your operation is probably your only option.

Well, I'll try to describe the best I can without giving out any "classified info." I am developing a signal generator that simulates products as they run accross the assembly line. Each of these products is defined in a buffer that is sent to the PCI6534. The length of the buffer corresponds to how many encoder counts are generated from the beginning to the end of the product(encoder counts generated by a PCI6602).
For this signal generator, I need to be able to change the length of the product on the fly. And so, I would need to change the length of the buffer before sending it to the output card.
