i have connected a 4wire analog(resistive) touchpanel to my cop8
microcontroller
for measurement the supply is directly done with the cop i/o pins. no
problem in generall.
but on measuring the voltage in y-direction i have a drift of the measured
voltage. y-voltage on the left side is different to
the y voltage on the left touch side if the y-position is constant.
this effect is not visible on the x-measurement.
anybody a solution ?
which switching fet are used usually in this application.
