Touch screens that have linux drivers

Embedded Linux Discussions

Hi,
I was looking at your 2064-K-TS-001-ND touch screen. Does that come with a linux driver? If not, do you have any touch screens that have linux drivers?
Thanks,
Chris

This TS050 Touchscreen is designed to work with Khadas Products:

  • Edge2
  • VIM4
  • VIM3/3L
  • Edge-V
  • Captain Carrier Board

It uses the FT5336 chipset, which is mainline. Making sure you're not a bot!

Hi Robert,

Thanks for replying. I hope you had a nice weekend. Thanks for providing the links. I did not see the FT5336 in the code you referenced, but I will assume the driver will mostly support the functionality.
Best Regards,
Chris

Dug into Khada’s git tree… common_drivers/arch/arm64/boot/dts/amlogic/kvim4.dts at khadas-vims-5.15.y · khadas/common_drivers · GitHub

	ft5336:ft5336@38 {
		compatible = "edt,edt-ft5336", "ft5x06";
		reg = <0x38>;
		interrupt_pin = <&gpio GPIOM_8 GPIO_ACTIVE_HIGH>;
		reset-gpios = <&gpio GPIOM_9 GPIO_ACTIVE_HIGH>;
		status = "okay";
	};

They have not touched the mainline input driver: History for drivers/input/touchscreen/edt-ft5x06.c - khadas/linux · GitHub

Hi Robert,

I failed to mention I am hoping to use 64 bit linux “amd64.” I believe this is a separate and distinct architecture from ARM64. I can keep looking. Thanks for all your efforts.

Best Regards,
Chris

Well, amd64 doesn’t use device-tree’s, and that display was designed for Khada products. So without knowing more about your hardware design, that display would probally be a bad choice.

For an off the shelf amd64 system, you’d be best looking HDMI screen with a USB based touchscreen adapter..

Something like: https://www.digikey.com/en/products/detail/dfrobot/DFR1170/26460582 ( 10.5” IPS 1920x1280 FHD 100% sRGB Portable USB-C and HDMI Display for Raspberry Pi They don’t list the ‘usb’ driver, probably native usb-mouse)

Hi Robert, The hardware design is very much fluid right now. There is nothing to know except we are hoping to use Linux for the software. I will look into what you suggested. Thanks for providing that link for the DF Robot. I am going to check it out. We really like Digi-Key.

Biggest thing you should figure out, is the display output, whether it’s lvds, eDP, HDMI etc.. That’ll get you into a panel, then what touchscreen drivers are available..
