Re: Brand new vna screen messed up

If, when the unit is running on battery only, the activity LED is flashing, check the LCD cable.

If the LED is not flashing - you've got other hardware or firmware problems. Since there are a number of manufacturers of the original Nanovna, and the quality varies, you'll have to go slow and eliminate each area. Good luck.

Could have your DFU file DiSlord to use and fix the problem with ?
It's not a bug, just a small limit I have placed on the DFU file format, I can modify to allow more DFU types. What did you use to compile to the DFU file with I wonder ? |

Apparently, I made a big mistake.? I let the Eclipse run and run.? It now has all
project boards known to man in it.? When I did a clean then build all, it took more than half an hour. I kept seeing the boards coming across on the Console, like F103Dicovery, then Olimex, then Nucleo, etc. Perhaps 100's of them. I guess I have to figure out how to select one project board only... It apparently, now, compiled almost all of them without errors. I will have to search the hard drive for the files... 73 Glen K4KV ps - Life was a lot more simple, when I wrote all the code myself and did not use Github |

If you bought it on eBay, you need to open a refund complaint with eBay support and send this unit back to get a refund.

It sounds like you were sent a faulty unit - ebay is very good at keeping its vendors honest. Aside from that, if you see the activity LED flashing (not the charge LED) when the display is white, it's most likely a display issue. If you're VERY careful, you can pop the LCD out of its frame and touch up the solder on its ribbon cable. On Tuesday, August 4, 2020, 2:49:08 p.m. EDT, bmanthug@... <bmanthug@...> wrote:

Re: building from source
Using an Ubuntu 18.04, here are the instructions in order to have a build from the excellent work of DiSlord
======================================================================================= wget sudo tar xfj gcc-arm-none-eabi-8-2018-q4-major-linux.tar.bz2 -C /usr/local PATH=/usr/local/gcc-arm-none-eabi-8-2018-q4-major/bin:$PATH git clone --single-branch --branch H4 cd NanoVNA git submodule update --init --recursive make =================================================================== After that, successful build output files reside in NanoVNA/build folder. Hope these help you guys. This is the method I use and it works and builds ok for me here. 73, Christos SV1EIA |
Re: NanoVNA application by OneOfEleven

I've finished off the firmware upload code but I canonly test on my little NanoVNA-H (STM32F072 MCU), I can't test on the H4, so proceed with caution.
If you try it and it fails then do let me know, and also make sure you have an ST-Link of some sorts to hand to recover your VNA. |
Re: NanoVNA-Saver on Linux OpenSuSE Leap 15.2
In addition to the packages mentioned below, it is also necessary to install opt-python38-setuptools from the OpenSuSE site. Then pip can do its magic.

Yes, you can install more than one OS - just re-partition your drive or install on different drives if you can.
