Buffered High-Speed Capture (NI 7350 only)

Buffered high-speed capture lets you create a buffer that holds captured positions that you can read asynchronously from the motion controller. The motion controller automatically arms the next high-speed capture, and writes the captured high-speed data into its onboard buffer. The enabling of high-speed capture occurs on a firmware-timed basis, which provides better frequency than the non-buffered high-speed capture method.

Buffered High-Speed Capture Algorithm

The following figure shows the basic algorithm for buffered high-speed captures applicable to both C/C++ and LabVIEW code.
