Hi,

i like m nanovna, but unfortunately the display is not the best one. The original alignment of the display is portrait, but using it in landscape looks not so good.

Is it possible to rotate the display in 90° like on the photo?

Hi ersoz,

Normal display is Landscape, 320 pixels wide x 240 high.
Your picture shows Portrait 240 pixels wide x 320 high, with an egg shaped Smith Chart

Change of orientation would involve software rework, perhaps unlikely.

Hi Boo,

the display seems some old lcd from phones or something, the polarisation of the display is for portrait use. If you look at it in portrait mode you will notice the difference. In landscape the viewing angle is narrow.

Maybe some dev can write menu option to rotate it, some libraries for displays have easy options to rotate.

Regards, ersoz

Try these firmware.

Hi DMR,

unfortunately the portrait mode is not working. The Menu is outside the display and not useable.

The programming on the UI seems to be "hardcoded" to the landscape mode.

Try these firmware.

Thank you for the files.
88.dfu is the same like the photo before, with the E8.dfu the display is rotated by 180°.

I just got my NanoVNA. Yep it's small.

I didn't realize how small it was until I really stared at the pictures. At first I was wondering how difficult it was to read the display due to the size but I frequently use my cellphone in excess of 80x25 text for ssh sessions, so I figured I'd have no problem reading the Nano, and sure enough it's big enough for me to not need a magnifying glass.

But I did notice that despite being able to read the text on it just fine, it is very tiring to look at it. Turns out that it's much easier to read with one eye closed because the display looks different depending on angle - just in landscape mode. In portrait mode, the display looks fine with both eyes and thus less tiring. I don't have this problem with my cellphone, just the NanoVNA -- because my cell phone has an IPS display where the NanoVNA uses the cheaper TN display.

Not here to bash on the cheap display, $50 is $50. But I have to seriously second that a firmware settable portrait mode be added, which unfortunately would probably be a major UI rewrite. I'm not sure how many people find looking at the display tiring or not, especially if one has to bring their eyes closer to the display due to size -- and this problem is worse the closer you are to the display.

Just my 2 cents, can't afford any more, else I'd have a Fieldfox :-)
