Touch problems on new 11.2 boards

      Touch problems on new 11.2 boards

      Hello,

      wanted to ask what's about issue 2213?

      Source Code

      1. 0002213: [Touch driver] Touch coordinate depends extremely on the pressure and are very inaccurately on bigger panels


      Some of our customers have problems with the touch. They told me that the touch does not react always when they press.
      Sometimes they have to press up to ten times until they see a reaction.
      I haven't such strong problems but sometimes I also have to press 2-3 times until it works.

      I have seen issue 2213 in the roadmap and would like to ask if there is maybe soon an update which probably solves also my problem?


      Best regards, Andy
      Hello,

      at the time we have no fix deadline for resolve this issue. Because a lot of customers use SVGA and XGA LCDs with NetDCU9.2/11.2 and touch without problems.
      Maybe we should try it first to resolve the issue be modification of drivers WCE Registry settings.

      Which additional settings are adjusted at the time?
