    LEDTS for XMC1200

    Hi,

    I'm going to get 5 touch buttons into my XMC 1200 project.
    There is no application note, only the Dave-App "LEDTS001"
    for XMC 4500.

    What can I do?

    Thank you for any help,
    Bernd

    Hi Bernd,

    Tell me what you want to do and I help you along. I have been working with this LEDTS for a few months now and have some code that may be helpful for you. Its not apps based, just a .c file and a .h file for LEDS plus some code in main.c.

    Best Regards
    Jurgen

    Hi Jurgen,

    Thank you for your answer. Are you a German?

    I'm going to develop a project with HD44780 LCD-Modul. I do need five touch buttons for some commands.
    I have some experience with Atmel controller and assembler but I'm a beginner in XMC1200.
    For LEDTS there is no application note and no app's for this controller and I'm trying to do it manual via datasheet.

    I think your experience could be very helpful for me.

    Regards,
    Bernd

    Hi Bernd,

    As promised, I have sent you an example on how to use the touch sense module.
    Please let me know if it is useful for you.

    Best Regards

    Hi Bernd,

    Between acrylic and glass, a touch button with a glass overlay has better sensitivity.
    The dielectric constant of glass is approximately thrice of acrylic. So, you can have a glass overlay that is about thrice as thick as an acrylic one for identical sensitivity.

    Best Regards,
    Syafii

    You could send me this example on my email rodrigo@eaglewingd.com.
    And another because it does not have an example of how to use this peripheral in DAVE4 ???

    Thank you so much
