Hello,
We are doing some EMC test on our device. We have a problem on NetDCU8, with the touch panel interface (J7).
Indeed this port appears to be damaged (because we change touch panel). Can you tell me if there is a driver (or protective chip)
between the touch panel (pin 15,16,17,18 of J7) and chip that operate this fonction. (is this signal direct to Analog port input adressed?).
Can repair this by soldering new drive chip? Can you give some information about touch panel interface hardware ?
Best Regards
Antonio
