Hi Andy, thank you very much I greatly appreciate you taking your time to help me out, this solved the issue, I overlooked it while going through the datasheet. I also adjusted the led current to be sure and started from the lowest setting. Now continuing with the project, I have eight of these sensors that I will control through a TCA9548A. Getting the 8th LED's on now works. If I get this to work, I will upgrade further if possibly to 64 pcs.
