I think this Problem would be better placed in the slimmer thread.
Anyway, did You use pull-up resistors for connecting the button?
If not, this could be the problem.

Hello,

I have now a running 4x20 LCD Display with a slimmer config like
https://github.com/terba/slimmer/wiki/Building-a-player.
But I have a litte Problem with the Buttons. The Rotary Encoder works
well but when I connected the Button from the Encoder to GPIO 6 for
example the PI received many pikeyd events from this Button.  I looks
like there is no debouncing . Did anyone know this Problem ?

You could try the HDMI version of the waveshare 3,5" touchpanel: 'link'
(https://www.waveshare.com/product/modules/oleds-lcds/raspberry-pi-lcd/3.5inch-hdmi-lcd.htm)
This one dont use the PIN 18.
You can stack it on the amp for the touch function but you need an
additional HDMI mini to HDMI cable for the display.

Hi Paul,

did you see a possibility to get a running config with TFT and Justboom
interface?
Alternatively, I would try  slimmer as an interface

Kind regards

horst

There is no way to disable that in the drivers.
