Swing load ksv 1,5

Did you select the Menu (3 bars, top left of screen)?

Trace settings are there.

I have this app working on my phone, but I can't figure out how to change traces. I click on a different trace bubble near the top and it just takes me to the settings for that trace. I'm assuming I'm missing something stupid here, can anyone help?

The Gekko version of the early nanoVNAs had the solder pads for an SD card slot - look at my forum photo from almost a year ago.
I actually added a slot to mine but then sold the unit and bought a better made one (no SD pads).

I have ordered an ST32F303 and I'm looking for the proper LCD panel so that I can convert my H into an H4.
I will add an SD slot to the PCB as well.

I bought the two units from Amazon Seesii USA with 2 day shipping on the
last one. Both units were labeled with 50 KHz starting frequency. But
they can start at 10 KHz if that is entered under Stimulus.

No for H need compile its own firmware, it have about 14kB free flash. Only Fat32 and short filenames need ~10kB (but i don`t test this for H firmware)
Also H version not have SD slot on PCB board, need add it, but this difficult for me (for my test).

DiSlord,
With your comment below, do you mean that the non-ExFat version of your firmware that supports the SD cards should work on an H if I add an SD slot?

DiSlord,

With this firmware I see :

Add support ExFAT filesystem and check work on my SD card

Samsung EVO Plus 128Gb HD XL

All worked, support ExFat need additional 4kB flash and can`t be suppoted on NanoVNA-H (if add card slot in it)
But on H4 stiil more flash space (only ~89kB + 64kB for calibration save used from 256kB)

On Samsung EVO Plus 128Gb HD XL read speed ~300kB/sec write ~190kB/s

Apologies in advance for what is probably a very basic question, but I am a complete newbie when it comes to Python. My Mac installation runs perfectly from the Terminal Window, but is it possible to run NanoVNASaver as an application rather than from the Terminal window?

I've tried to set up a "Run Shell Script" Application using Automator, but I'm not sure of how the path needs to be set up or even if this approach is the best one to use. I'm using the following command: python3 /Users/john/nanovna-saver/NanoVNASaver, but I get the following error:
Traceback (most recent call last):

ModuleNotFoundError: No module named 'PyQt5'

I have also tried "cd /Users/john/nanovna-saver" and then NanoVNASaver, but I get a different error: -: line 1: NanoVNASaver: command not found.

I receive no errors when executing "NanoVNASaver" from the Terminal Window. I am running Catalina 10.15.4. Many thanks in advance for any possible suggestions!

Hi DiSlord,

It's working now , see screenshot attached (after 2 port calibration).

This is shown in Tera Term :

?CMD0 Ok
?CMD8 Ok
?CMD8 0xAA010000
?CMD8 Ok, run ACMD41
?ACMD41 99
?ACMD41 0x0080FFC0

Thanks again for you fantastic work.

Thanks for made test (i don`t found old SD cards at home for check it)

As i see all SD card types work

SD cards work
SD HC cards work
SD XL cards should work if format to Fat32, but need test, possible i enable exFat support

Read/Write speed not big, but this limits of SD card SPI bus mode and processor.

In future i try

revert SPI speed slowdown to 36MHz
add save s1p and s2p data files as *.s1p or *.s2p (need read more about this format, it just text but possible variants)

I think this a good extend NanoVNA capabilities.

Thank you very much, it works now.

Found my error in card type detect

Yes, but you card answer
CMD58 CCR = 0x0080FF80
Not set Card Capacity Status (CCS) bit

Need read datasheet

It still doesn't work, SDHC card uses block as read/write unit and small capacity SD card uses byte as read/write unit, is there no driver for small capacity SD card?

Yes possible old cards can`t work on high SPI speed like 36MHz

I try set 18MHz speed for work, this little slowdown write from 150kB/s to 140kB/s

Also, i found RTC clock (internal timer) run to fast, as i see in datacheet STM32F303 use internal 40kHz LSI, but ChibiOS use default 32kHz value settings

SD_SendCmd CMD17, 0x20, 0x0000003F

Its mean Card answer on CMD17 (read sector) Incorrect address specified
1 variant i`m not correct detect card type (old cards use another adress mode)
2 variant card not correct deocode adress (from bigger speed)

Try this variant vs slowdown SPI for SD card (to 18MHz) and fixed RTC clock (for set normal clock timer need run time command and set new time)
Also i add read/write speed log stat for test

On my cards result ~180-220kB/s for read and ~90-140kB/s for write.

Hello DiSlord, I installed a microSD card slot and tested that both 8GB and 32GB microSDHC cards can work normally, but I found an ancient 1GB microSD card that does not work.

The following is the information displayed by the terminal when using a 1GB microSD card.

CMD0 Ok
CMD8 Ok
CMD8 0xAA010000
CMD8 Ok, ACMD41 99
CMD58 CCR = 0x0080FF80

Thank you very much for your guidance. Now there is a problem that 617DB-1023 has been discontinued. I tried to use YB006T-1023 instead, but the consistency of YB006T-1023 will be worse. I need to find more 617DB-1023 before larger production Or alternatives with consistent performance.
