MCF52277RM - 4 wire resistive touch panel interface.

Question asked by Anuj Topiwala on Apr 13, 2015

Using MCF52277RM I need to establish 4 wire resistive touch panel interface. But I have 6-8 inch cable extending from the touch panel to main board. Will the inbuilt Touch controller with ADC biasing circuit be enough for noise free interface. The touch panel resistance is 200 ~900 ohm both x and y side with < 1.5 % linearity.
