Re: Speed of banner sensor

We were able to using Kevin's code were able to get Quadrature (two banners) from a four edge (one 1/4 white 1/4 black etc.) motor coupler on Cim motors running flat out, this was confirmed in code and with a scope. Last year after ship date. We could not, get anything else to work. As I recall there are spces for banners on their website. Things vary with the model, And some teams have reported that they drop out every now and again. Cims flat out are around 4800 rpm and since the interrupt was on both edges this was about 320 Hz as I recall, scope read about 160 Hz as it was only triggering on either falling or rising edges Good luck
