Part Number: MSP430FR2675

Hello,

Does this touchpad support multi-touch?

  • Yes, both mutual mode and self mode all support multi-touch.

  • Hello, Eason

    Thanks for the reply.
    The CapTIvate Technology Guide does not explain much about the touchpad.
    There is no diagram of the touchpad detecting multi-touch.
    Also, Customers cannot verify that the touchpad supports multi-touch because no evaluation boards have been released for the touchpad.
    For this reason, we need a screenshot of the touchpad detecting multi-touch in the GUI in your environment. I would appreciate it if you could show us.

    Best regards,
    DDdoor

  • Sorry, to be late.

    Do you mean trackpad? If so, I must say, currently it only support justify one finger. It is because of software design not the CapTIvate technology itself.

    If you want the example code and hardware, I can share with you.

  • Hello,Eason

    Thanks for the reply. Thanks also for the video. I have explained the content to the customer.
    Customer's product will have a slider, buttons and a touch pad (track pad).
    Are there any guidelines regarding clearances, such as what customers should be aware of regarding placement between each sensor?

    Best regards,
