Will their be GitHub - lvgl/lv_drivers: TFT and touch pad drivers for LVGL embedded GUI library for Version 8.0.0
The existing drivers should remain compatible with v8.
I go these errors when I try 8.0.0

LVGL 8 hasn’t been released yet so there is no lv_drivers release on PlatformIO for v8. You would have to use the master branch.
Hi,
isn’t it released now ? Does someone have a version 8 compatible evdev-driver ready ? Asking the community. Thanks in advance.
Hi,
evdev-driver works if you change the signatures (from return bool to return void) and a few assignments (from drv->disp->driver.hor_res to drv->disp->driver->hor_res for instance). It works in my case but maybe it is buggy and there is more to it and that is why it hasn’t been merged, yet.
