hooray at last,the answer i needed,thanks eric 73

Unless I misread the diagram those displays have 40 pins. Good luck on your search. Did you check that they use the same controller?

You need the resistive touch panel.

yes they do,i need to know if i need the resistive touchscreen or the capacitive one!

Do the LCD modules you selected have 18 pin connectors as described in the wiki? -- NanoVNA Wiki: /g/nanovna-users/wiki/home NanoVNA Files: /g/nanovna-users/files

Calm down Paul! No one can tell you which one is better because it's personal preference. Besides, there is only one person who attempted to change the display and that info is in the Wiki/Files

John, If you're sweeping an antenna that's in close proximity to the VNA, leakage from the cables is probably not going to be a limiting factor. Other aspects of cable quality (impedance bumps at

Hi aa_Talaat Sort of right. For the input impedance measurements you may calibrate Ch0 on the output side the inserted attenuator. 40dB is a bit tough as it will introduce larger measurement

There is limited output power control on the nanoVNA you can use (limited, no 30dB control) Use a terminal emulator to connect to the nanoVNA and you can use the "power" command to 4 levels of output

I build a common emitter amplifier based on BFP420 BJT, and would like to measure its gain and input and output impedance. As the gain should be within 25dB, so I connected a 40dB 50 ohm input/output

Hi, Thanks to all who appreciated the software. Consider it as my contribution to the group. Kind regards, neb

bug reports for this gcc bug are already exists. I just fixed NanoVNA code to avoid it.

Hi Rune, please don't think that I am referring to your own excellent software. I know it works when all the bits are in the right place ;) What I refer to is the general disease of of always needing

And file a bug report?

Isnt it amazing how i cant get an answer to a simple question!,if i wanted to use a tab i would have asked that!!,pointless as my tab doesent support the app,just wanted to know what screen to get out

just installed gcc and tested it. The root of cause is GCC compiler bug. It produces garbage code. I will implement workaround for this GCC compiler bug.

Hi Andy, Python 2.7 is end-of-life in little over a month. Developing new software using that cannot reasonably be encouraged. If anyone wants to port NanoVNA-Saver to other platforms or languages, it

file board.c, line 65

I don't have gcc at the moment, so I cannot implement patch for your compiler. You can try the following change: volatile uint32_t dfu_reset_to_bootloader_magic __attribute__ ((section (".noinit")));
