[Feature Request] Display rotation possible?
lechk82 opened this issue · comments
First of all: I have been searching for a way to integrate LVGL and esphome for a long time, and I am very impressed by this project.
Is there a way to adjust the display orientation using the rotation parameter?
Two options:
- Clone the repo and do this #7
- Optionally, make it configurable via YAML and create a PR.
Hello I tried with value 0 ; 2 ; 3 but the screen is rotatted only bu 90° right and with a lot of glitch. Any help on the correct value to use ?
Hello I tried with value 0 ; 2 ; 3 but the screen is rotatted only bu 90° right and with a lot of glitch. Any help on the correct value to use ?
I initially had the same problem and solved it as follows:
hd_device_sc01_plus.cpp:
disp_drv.rotated = 0;
disp_drv.sw_rotate = 0;
LGFX.cpp:
cfg.offset_rotation = 2;
Oh OK, my need is a bit different, I need to rotate by 180° (because of my dock I cant put the screen in the other way)
Do you know the value for 180° ?
Thank you !
Tested 0,1,2,3 for cfg.offset_rotation giving me 0, 90,180,270 degrees, respectively. choose the one you like
Hello do you modify the 2 occurences of cfg.offset_rotation in LGFX.cpp or only one ?
do you modify anything in hd_device_sc01_plus ? (what is your values of disp_drv.rotated and disp_drv.sw_rotate ) ?
thank you
@multinet33 My mistake was, that I changed cfg.offset_rotation = 0; in line 73. Changing cfg.offset_rotation in line 40 works for me.
For the life in me, I can't figure this one out. I did set disp_drv.rotated = 0; and disp_drv.sw_rotate = 0; and I also changed both line 40 and 73 to 2. Screen is still in Landscape. Am I missing something?
Make sure that disp_drv.rotated = 0; and disp_drv.sw_rotate = 0 are not overwritten, as esphome sometimes pulls the git sources. In addition, a clean build is sometimes helpful
I cloned the git - https://github.com/genasoft/ha_deck/blob/main/components/hd_device_sc01_plus/hd_device_sc01_plus.cpp and they are set to 0. On top, this clone is brand new as I wanted to start fresh (initially I thought that this might be causing the problem).
I have also deleted the instance in ESPhome (HA) - all cleaned from BUILD, STORAGE and IDEDATA.
Do I need to swap HEIGHT and WIDTH variables?
apart from the changes mentioned, i haven't changed anything else, so specifically only this:
hd_device_sc01_plus.cpp:
disp_drv.rotated = 0; disp_drv.sw_rotate = 0;LGFX.cpp:
cfg.offset_rotation = 2;
I suspect that some caches remain in the build directory in your case
You could fork the repo, hardcode the rotation settings in your fork end use that one directly as a component.
I am deleting the full build directory, so unless there is somewhere else cache, that shouldn't be the case.
strange-v, any idea that would help solve the issue?

This is what I did - https://github.com/genasoft/ha_deck/tree/main
right, i've just seen it, i'll try your component and see what comes out for me
your fork gave me an error, so I forked it myself and it works as expected. I also removed the background image because it overshoots the rotated image area. try it with my fork: https://github.com/lechk82/ha_deck
Ha, it worked with your fork. This is very weird. Could it be because of the background?
Thanks
On my side anything else that 0 ( 1 2 3 ) in LGFX.cpp: cfg.offset_rotation line 40 put the screen in portait mode
so I can have only one orientation in landscape on only one orientation in portrait
Make sure before re-compiling, you clean up everything - build, idedata, storage,cache/platformio/cache/http, external_components
I compile it via ESPhome under home assistant
before I always make a clean build files so it download all dependencies every times
is it the correct way to do it ?
i think yes because every time I put back 0 I get my screen landscape (but I would like it in 180 degrees because I can’t reverse my screen due to my case)
The directories that I gave you are within the ESPHOME docker image. Before any new build, you have to go in there and clean up. I was having a lot of misery when I didn't do a complete clean up.
