Hi I've been trying to use Arduino 2560 to blink 2 LEDs at different frequencies(150&200Hz) - code attached below.

However, it seems like LEDs aren't being detected by the Prophesee EVK4 camera - (bias settings are at default (recording attached)) when the ROI is selected to narrow down region to LEDs.

Occasionally I see a warning message on command prompt saying frequencies aren't accurate but other times there's neither a warning nor any detection.
