DLPC3478: Image flipping with internal patterns using WriteDisplayImageOrientation

Øyvind2929

Part Number: DLPC3478

I am working on an application using DLPC3478 and internal pattern mode. I can successfully project patterns.

However, I am not able to use the API to flip the image. It seems like the projected image is the same, using either of these configurations:

// This configuration ....

Dlpc347X::WriteDisplayImageOrientation(Dlpc347X::IR_NO_ROTATION, Dlpc347X::IF_IMAGE_FLIPPED, Dlpc347X::IF_IMAGE_FLIPPED);

// ...results in the same image orientation as using this configuration instead

Dlpc347X::WriteDisplayImageOrientation(Dlpc347X::IR_NO_ROTATION, Dlpc347X::IF_IMAGE_NOT_FLIPPED, Dlpc347X::IF_IMAGE_NOT_FLIPPED);

I am wondering if the image flipping is supported using internal pattern mode? And if it is supported, is there any particular order of commands (or similar) that I need to use in order to flip the projected image?

Dear Vivek,

I can share more details about the application and requirements, but I would prefer not to do so in this public forum.

My question is just if the above mentioned function is supposed to work on internal patterns or not? The documentation does not seem to describe which modes of operation the function supports.

Best regards,

Hi Oyvind,

The image flipping feature is supported in the internal patterns mode. You can look into the software programmer's guide for more info related to the

'Write Display Image Orientation' command . The link for the same is - https://www.ti.com/lit/pdf/dlpu075
