How To install the "extra widgets", eg lv_meter?

How-to
1

What do you want to achieve?

I want to create a “meter” widget as described in the “extra widgets” section of the documentation.

What have you tried so far?

I have just tried to use the example given in the documentation, but all the lv_meter_… functions were marked as non-existing.

Code to reproduce

Just try the example from Meter (lv_meter) — LVGL documentation.

Screenshot and/or video

No screenshot or video available as I can’t find the “Extra Widgets”!

Environment

  • Cheap Yellow Display (CYD):
  • LVGL version: 9.4.0

I just need to find the package to install.

Thanks in advance,
Josef
