Hi all!
I don't know if I have problem, a faulty display or a firmware bug. I'm testing the function L/C Match. I enable the function by clicking "MARKER/SMITH VALUE/L/C MATCH" in the menu system, but I get no visible text on my screen! I also have a nanoVNA SAA-2N, and it's working nice in this model, but not in the NanoVNA H4.....
By studying the screen very close, I can see parts of letters. I can see the lines are interferred with black pixels! I can se the pattern changes when moving the marker and it seems to mee that the letters are written in black, and therefor they are not shown. Anyone out there seen this, or is it only me/my system?
I compared the SAA2N and the H4, and there is something odd with the SAA2N too, not really a problem, just a bit odd. When using the function on the SAA2N, some of the results fro the L/C Match calculation is not removed from the screen. This only happens when using a stylus to move the marker, and not when moving the push buttons!
I almost forgot to mention the firmware version information :-)
NanoVNA-H 4 have got the 1.0.45 from Dec 15 2020 - 20-03:40
The NanoVNA SAA 2N have got version: git-202001226-7b1abc9 Built Time: Dec 27 2020 - 00:35:52
Anyone else seen this problems?
