Hi team,

Is there an apps note to describe the theory of dual touch recognition mechanism using TSC2013-Q1?

I would like to know how to use X1, X2, Y1, Y2, IX, IY data to calculate coordination in double touch.

regards,

Hello Shinji,

Other than what may be in the data sheet, we do not have any app notes describing the use of this feature. I can, however, provide the reference firmware that makes use of this feature. This should be a good starting point on how to implement dual touch.
