LCD Rotate Display 180 Degrees

Good Day

I'm trying to integrate LCD  NHD-5.0-800480TF-ATXL into our system.

The display is now working. However due to hardware and physical location of the LCD I need to rotate the display 180 degrees.

I tried using updating files as mentioned in this discussionRotate the 3.5 inch LCD screen to 180 degree.

The result is it will only rotate the logo and when i run some GUI applications or display images it will revert back.

Any ideas what needs to be updated to successfully rotate the screen?

Thanks

Hello carlovalgocela and karinavalencia,

As noted in the same thread you have in Timesys Support, it appears the framebuffer driver does not support rotation in it's default state; an application or framework, such as Qt or X must be leveraged, unless the driver is customized to rotate. If this is a hard requirement, please contact Timesys Sales to discuss a dedicated engineer to integrate.

Thank you,

Timesys Support

Hi Carlo,

If you use QT4 library, you can rotate screen with 'transformed" option like that : YourApp -qws -display transformed:rot180:1.

Regards,

Emmanuel
