touchpad three dimensional
For my application in need more capsenses than the number of pin available on my design. I would like to use a matrix button or touchpad but i'm confused. It is write that "When more than one row or column sensor is in the TOUCH state, then the finger location cannot be resolved, and the situation is considered an invalid condition."
My question is, is there any way to measure more capsense with the 3rd dimension?
If I use a matrix 3 by 3 for example, and I measure step by step
I am able to measure my 9 electrodes right?
Thank you very much
