I'm having great difficulty navigating between drop downs on my NanoVNA-H 4 edy555 design version 0.5.0.
First thing, I thought the first, 'about screen' disappeared after a short time, mine doesn't. If I tap the screen I get Display, marker,
stimulus, etc. I tapped or held and got trace. format, scale, etc. Then I tapped Format and got trace 0, 1, 2, etc. that's not correct.
Now tapping back only causes the grid to come and go with each tap. I did tap trace 0 and it did bring up the yellow Ch 0 in he upper left.
But back just keeps cycling the grid on and off. If I tap back enough it finally goes back to Trace, Format, Scale, etc. I can not get format to show.
It seems to know when the screen is tapped, but it doe not make the change as expected.
Would a firmware update help this?
Any thoughts?
Thanks, Mikek
