All the examples are broken

[gitcnd]

Except the first, all others here https://docs.lvgl.io/master/examples.html say this:-

Running the SDL lvgl version
Traceback (most recent call last):
  File "<stdin>", line , in <module>
AttributeError: no such attribute

... in the simulator.

e.g. here:-

https://sim.lvgl.io/v9.0/micropython/ports/javascript/index.html?script_startup=https://raw.githubusercontent.com/lvgl/lvgl/0bdd54abedf352e82acfbaabe8be48324f9435a2/examples/header.py&script=https://raw.githubusercontent.com/lvgl/lvgl/0bdd54abedf352e82acfbaabe8be48324f9435a2/examples/get_started/lv_example_get_started_2.py

@embeddedt Can you take a look at it? There were a larger refactoring in LVGL's API, and probably some MicroPython-JS parts were not updated. Most importantly lv_disp_... was renamed to lv_display_...

Because lv_micropython v9 development is happening on the feat/multi-instance branch, rather than master, the changes are not merged to the simulator's branch automatically. After merging feat/multi-instance manually the examples appear to be functional again (including the URL above).

Nice!! works again.

I'm interested in building this as a loadable binary .mpy for (at least) my esp32. Is there someone I can chat with about this effort?

e.g. https://forum.lvgl.io/t/standalone-binary-mpy-module-for-lvgl-so-we-can-just-use-it-in-micropython/13518

Thank you @embeddedt. Could you tell exactly which repo's which branch is used by the simulator?

I'll reply in the forum.

The v9 simulator uses the lvgl_javascript_v9 branch of the https://github.com/lvgl/lv_micropython repository.

The workflow that merges new commits on master into that branch is here: https://github.com/lvgl/lv_micropython/blob/master/.github/workflows/merge-to-js.yml

Clear, thank you!
