I need some information to find out what is happening with some os my resistive touchscreens.
I have the following issue: after a couple of month of normal usage for my own virtual terminal, the touchscreen stops responding.
After all of the test that we made, always have the very same problem: the y-axis circuit in the touchscreen is open (there´s no resistance measurement).
Do you have any idea about this problem? I have the very same circuit that you have in almost all of your demo circuits…
Please, any ideas will be good for us to keep researching…
