Hi,

   

I am trying to design a new layout for a slider in the form for an arc of a circle. I have four pads on the arc. I have configured this to be a radial slider. But when I use the API to get the centroid position the maximum value of the centroid gets stuck at 3/4 of the resolution and in my case 75/100. I removed the last pad from the slider so that it had 3 pads but then it gets stuck to a maximum value of 2/3 of the resolution ie. around 66. 

   

The radial slider in the capsense datasheet is defined as 

   

"A radial slider is similar to a linear slider except that the sensors are placed in a circle"

   

Does this mean that I cannot have just a portion of the circle as layout for a radial slider and the last slider pad has to be close to the first slider pad?

   

The layout of the pads is attached in the PNG file. 

   

Regards

I think that you are quite right. The calculation of the actual finger position always includes the next pad which isn't there for your arc.

   

I would suggest you to define your layout as a linear slider.
