Grabs wrong buffer when continuosuly cycling without taking data #1

This appears to be happening when PXIe system continuously cycles while CsPy does not acquire data. (PXI communication box checked).

Blackfly server intermittently retrieves wrong image buffer possibly one before I want. I guess if Blackfly server runs retrievebuffer and if the buffer was filled by fake cycle, it pulls that one. Going to figure out how to not grab images during fake cycle.

There might be a clear buffer command that could be called when processing the start command.

You could try changing the grab_mode to drop_frames instead of buffer_frames. I think I set it to buffer_frames, but the behavior if the buffer filled up was not defined in the reference manual.
