My touchscreen has four leads comming out via FPC, according literature they should be +X -X , +Y -Y.
now for making sure which is +X and -X and which one is -Y +Y, i was measuring resitance between the pins
i got no connections infinite resistance between pin 1 and 3 and 300 ohms between pin 2 and 4,
I am going to design controller for Touchscreen but i doubt touchscreen itself i have got two of those and both are showing similar behaviour
that is only between two pins i am getting resistance i.e pin 2 and 4 , and in rest all combinations (1,2) (3,4) (1,3) i am getting infinite resistance...
these are possible combinations
1,2
1,3
1,4
2,3
2,4 ---> here only i am getting 300 ohms
3,4
i think i should get few hundred ohm between 1,3 also..
what do you say..
or is there any other way..
