<![CDATA[[Tab5] Lvgl Testing]]>Tab5 has a big screen. So I'm plan use it to learn lvgl on it.
But bad news is seems UIFlow2.0 using LVGL9, and rare data about that.

About issue of UIflow2.0:

  1. While using widget with callback, in callback function use lv.get_target() seems can't get the object which fire event.
  2. I am trying use slider, basicly function normal. Except leave finger out of screen after adjusting slider, slider holder will jump to position of 100%.

  1. Slider Odd (Auto jump to max. value. I think might be something wrong in update loop.)
  2. Can't success in using grad_dsc_t (can do in style way, but couldn't do in drawing API)

other's going well.
I prefer LVGL with micropython, althought slow in speed, and troublesome in callback function. But more Object Oriental to make coding logically (I think more clearly.)

And ...
It's so easy use LVGL in Tab5. Same version UIFlow2.0 firmware in Core2 AWE, have to run M5.begin first. (In someway , Tab5 might wrong in someway....)

  1. Sorry!! My Bad.
    [LVGL8.4] lv.get_target() --> [LVGL9.0] lv.get_target_obj()

  2. slider : Still odd.

** testing LVGL python examples in the middle way. So far so good.
