Hi! I'm tring to increase higer frame rate to 500 samples/s. I have tried the xep_fps_test.py and it works well. But when I make the same configures as in the xep_fps_test.py and try to make recording, no recording file show up after the fps is set above 40. My matlab for recording is attached, could you please help me find where is the problem? The current fps is set to 40 and it will fail to provide recording file when fps is set above 40.
