Add support for keyboard/mouse

[septatrix]

Is it possible to use the keyboard/mouse when running this demo? Currently this does not seem to be the case.

Adding rudimentary keyboard support might not be too hard as one can just read from stdin (or use termios to not wait for Enter). Mouse support might be harder but should also be possible using /dev/input/mouse or similar.

Hi,

We have drivers for libinput and evdev. See here.

[septatrix]

Would you accept a PR for adding them to this example or is that out of scope for this repo?

Sure!

The libinput driver got support for handling touch, mouse and keyboard too via

libinput_find_devs();
libinput_init_state();
libinput_read_state();

These updates were added by @Johennes, so there are any questions probably he can help. :slightly_smiling_face:

@kisvegabor
Any reason why this sample repo is not updated with latest drivers which supports SDL including touch?

I have a RPI 3B with Waveshare 2.8" 480x640 TFT with capacitive touch. Demo shows up on the display but now trying to get touch working.

What all changes are required to make it work?

By just switching drivers to master and copying drv_conf to local gives this error. Trying to avoid spending time troubleshooting for now.

Just updated, see https://github.com/lvgl/lv_port_linux_frame_buffer/issues/20#issuecomment-1079006480

Basically, it's just the lack of manpower that we can't keep all the ports up to date. :slightly_frowning_face:

@kisvegabor I am trying to create samples with documentation which just works. Already did with WT32-SC01 + Arduino & ESP-IDF versions.

After I shared LVGL+WT32-SC01 on FB groups, several people bought WT32-SC01 as well. Trying to do what I can to support LVGL 😊

Sounds great, thank you! :slightly_smiling_face:

Still a relevant feature proposal

[kisvegabor]

Have you tried the libinput drivers mentioned here?
