Display offset Y

[ForTest]

Hi,

is it possible to add an Y offset to the screen?

I'm using SSD1963

Thanks

I try to explain better.

I want the display to add for example 10 px as offset to the Y axis, so if I tell it to plot at x:0 y:0 it actually plots it at x:0 y:10

The easiest thing to do is to modify all the gdisp routines and add this offset to the y component.

I was wondering if anyone knew of a way to set the video controller at init already with this offset.

Can you elaborate a bit on what you want to achieve? It this offset desired to be global to everything the display displays or just for certain widgets? Also, is this a permanent measure or should this offset change during runtime?

If this is just a measure to align the UI of a machine with a display behind a panel I would recommend modifying the GDISP driver directly. This way your application remains unchanged and upgrading to future versions of µGFX will not require any changes.

It's a permanent offset. It should works for all widgets and in general for everything plotted on the display.

In that case I'd recommend to adjust whatever GDISP driver you have to handle that adjustment for you.
How to do this depends on the GDISP driver model used but the overall idea remains the same: shift each pixel before the display controller gets access to it.

Did you manage to get this working?
