How to porting v7.0 apps to v8.0

How-to
1

Description

I recently shifted my code to v8.0, I get random compile errors, I assume the new release doesn’t use lvgl tasks, how do I port tasks in the new release ?

What MCU/Processor/Board and compiler are you using?

esp32

What LVGL version are you using?

v8.0

2

They were renamed to timers and the priority system no longer exists. Aside from that, the behavior is identical in v8.

3

Is it recommended to port tov v8.0 now ? Is it stable enough, as even lv_qr_code doesn’t work with it anymore.

4

lv_lib_qrcode was updated by @kisvegabor a while ago, so it should be working on v8 already.

Nonetheless, I would personally recommend sticking with v7 if you have an existing project, as there is a lot which has changed between the two versions.

Cool, I’ll spend at max one day to port, hopefully I’ll be able to, if I fail, I’ll fallback to v7.0

But guys, you can’t break so much between versions, atleast a detailed porting guide, will help us all.

Thanks

See this link https://docs.lvgl.io/master/CHANGELOG.html#migrating-from-v7-to-v8 in the docs. I found it useful, but by no means complete. I must say that it has taken me much longer than a day, but so far well worth it. LV8.0 is so much cleaner and compact in its implementation, thus I suppose the need for breaking changes.
