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,

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.

Hello StefanoM.

I'm a few days trying to use this touch sense to work, but I have not had success yet, nor any response from the forum.

In Dave4.4 I was scouring the help GLOBAL_LEDTS, it helps a lot, but I still have not found the function that does the reading of the pin.

Hope this helps you soon.

I also need an example of using the LEDTS peripheral to read a pin. I do not need to drive any LEDs. I just need to read one pin.
