Issue enabling Opacity

General discussion
1

As mentioned on another post, I am trying to play with the lv_chart widget.
I would like to use the example that used a faded background under the series so I set LV_COLOR_SCREEN_TRANSP to 1 in lv_conf.h (LV_COLOR_DEPTH is set to 32). However, when I compile my application I get lots of errors (see attached showing some of the errors).

Can anyone help?

Hi,

There were some reworks and maybe it was broken at some point, however, I’ve jest tested it an it worked well with the latest master.

Okay, thanks for that.
I will ensure I have the latest release and will try again.

Best Regards
