Add an rotary knob object

Hi,
I work on an GUI with STM32F746DISCO and a larger 7β€œ Touch TFT.
LVGL works very well!

Often i use Sliders for MIDI or Audio Control and sometimes it could be better to have a Rotary knob for adjust Audio or MIDI values => for example loudness.

A rotary knob for Parameter Control is my greatest wish for LVGL!

Best regards
Werner

Thank you for the idea. It’d be really useful.
I’l think about it!

With the new object designs in 7.0 it should be possible to combine both this feature request and New type of slider, any ideas? into the same object. We’d just need an option to choose the degree range of the knob.

Hi,
I work allmost with LVGL at Applications for Musical instruments and with MIDI Control.
Take a Look at TOUCHOSC! A GUI with simple Control Elements.
