Anyone knows proces of sensing touch position on strip like there are two electrodes connected on strip which is made of 18 pads connected in series with resistors .
I know that positions are already defined with algorithms buth im not shure which path is taking for caculation:
My definition:
burst impulses travel from electrode 1 through slider and charging CS2 so if i touch slider on "position 6" i will add paralel capacitance to that spot and analog result for added charge is already defined so the only thing to do is measure the voltage on CS2 and the touch spot is fixed with amount ofvoltage.Process is done in both way for recalibration of end positions
----------------------------------------
If anyone knows how it works please help me its giving me a headache,cheers
