Help with Giga Display rotate 180 degrees?

Projects General Guidance
1

Hello!

I'm working on a project with the Arduino Giga R1 Wifi and the Arduino Giga Display.
I'm building a UI for the project using LVGL 8.3.11, and am using the Arduino_H7_Video library for setting up the display.

My issue is that the physical display need to be oriented a specific way within the enclosure I have for it (in order to maintain access to the USB port), but that specific orientation results in my interface being upside down.

How can I go about rotating the display or interface 180 degrees? or flipping the display on X and Y. I've tried digging into the H7 video library to see what drivers are being used for the Display so In can try and make changes there. But I have come up with nothing. Would really appreciate some help!

My sketch is currently setup as per this tutorial for getting the display working with LVGL 8.3.11 and Squarline Studio.

If you're using the TFT_eSPI library with LVGL, use the setrotation call
tft.setRotation( 1 );

This is how I've setup the display:

I just found the answer, using same hardware I think the syntax is wrong, instead of lv_display_set... use lv_disp_set... . That is what everything else nearby used so I tried it and got rotation!

It's right in the tutorial you linked to.

Rotating the SquareLine UI

If there is a need to rotate the UI created in SquareLine on the GIGA Display Shield, there is a single line that needs to be added to one of the exported library files. In the

/ui/src

folder, find the

ui.c

file and open it.

The code we need to add is:

lv_display_set_rotation(dispp, rotation);

The rotation can be set to 0, 90, 180 or 270 depending on how much you want to rotate the UI.

If the lv_display_set_rotation(dispp, rotation); method works, is it possible to implement this dynamically at runtime instead of manually editing the ui.c file? This would make it more flexible for different use cases.
