PMW3360 Pixart

Anyone building trackballs that have issues with tracking dark gray (graphite) to dark green spectrum? Wondering if anyone that’s had this issue has tested it in a PMW3389.

What you're referring to as a "spectrum" here? Illumination by green LED?

I can't get the particular sensor to properly track Dark Green and Dark Gray trackballs. Dark Gray works ok but skips. Dark green doesn't do well with tracking going to the right. Was wondering if anyone else had ran into this issue.

Yeah. I tried this. I even let the trackball almost sit on the sensor lens and i the issue remained. Dark Green once it got a certain distance the sensor couldn’t see the ball at all.
