Triggering

[merbanan]

Hi, I was thinking of how to implement triggering. Is it possible to run a GPIF program once and then fetch the FIFO data at a later time ? On the sainsmart the calibration pulse can be connected to the RDY0 pin and thus start GPIF program zero quite quickly. I just need a way to get the generated buffer without anything overwriting the FIFO before I am able to fetch it.

I think the FIFO is never overwritten. If it is full, no new samples are acquired until a block is successfully sent over USB. You may also try to write a FIFO program that checks for fifo full condition and then terminates. I don't have any experience writing such a program, though.
