Martin, did you try a calibration?
--

Thanks for the super quick response.?
Just done a CONFIG/MORE/CLEAR CONFIG? then 1234? enter.

sadly the unit has same issue after that procedure.
I wish I had made a note of the original formware version so that I could try and to back to that and check.?

Martin

The image suggests a failed calibration, possibly caused by updating the FW and not doing a CLEAR CONFIG
Can you try a CONFIG/MORE/CLEAR CONFIG?

Hi.?? Has anyone seen this issue before ??
My Tiny SA is original version 0.3 hardware purchased a long long time ago...
Was working OK with no problems but had original firmware in it, so I devided to update it.
Using the Tiny-SA app uploaded the latest tinySA_v1.4-142-ge5dbf70.bin firmware and power cycled unit.
Screen now shows random pulses and fails all selftests :(

I've tried other versions of older firmware and unit still exhibits same behaviour.




Regards

Martin

Push the jog switch to the side (not down) and switch the tinySA off and on, release the jog switch
If this removes the weird spikes in the regular scan do a CALIBRATION and run the selftest

I've had my TinySA for a year or so now, and it's always worked well.

Yesterday I looked at the signal from my UV-5R by leaving the sockets unconnected - just the yellow end caps on them!
It worked great... the large attenuation from having no antenna meant I could see a small signal around 144MHz.

I flashed the latest firmware on it. Tried calibration and it all failed!
I flashed my original firmware (1.4.83-gbe4f4d6 built Apr 13, 2023)

Calibration still failed! So did the self test. =(

When I say "failed" - I mean the WHOLE set of tests (besides the screen)... not just the Attenuation one (Test 12)!

I'm surprised a little - I thought I was safe with no antenna attached.... guess I've fried lots of stuff. =(

Can anyone confirm?

I turn it on :



This is the result of calibration with a connector across the sockets.

Can you try if a terminal emulator SW like Tera can connect to the tinySA serial port?

Its a clone

Guess the file rename should be possible?

Yes, rename possible
I think add "Name" button like "DEL", after enable it, next click on filename - call text input dialog for enter name and after rename it if ok (but leave file extension)
need use?f_rename(old, new) function
Add use this function increase code size

I was not actually expecting a programmatic resort and had assumed the underlying core SD i/o would support directory file listing with multiple sort options (like filename, create date, modify date) so the list of filenames could just be retrieved again in the desired order. Appears my assumption was wrong.

@ctech, Here is a link to the source on Github. If you find a way to do sorting within the TinySA memory limits, please submit a pull request.

TinySA contain only 48k RAM, for all

I add file browser option in NanoVNA and Tiny. For all I use 4k RAM, shared vs LCD buffer (for all, include read buffers, FAT cache, and small text draw buffer)
Also limits in code size.
For sorting need load all filenames (if use short names 8 byte for file, for long name up to 255 bytes)

Interesting how possible sort something and not load in memory, sort operation mean swap objects, lot of swaps. There store sort results?

PS?adding a file browser even in this form, given the resource limitations, was quite a non-trivial task.

In the wiki you can find the link to the github repository with the code.
Feel free to study how the file names are read from the SD card and displayed on the screen
Any proposal for some way to sort without loading all file names in memory is most welcome.

@Erik
I would think an in-place sort wouldn't use any extra memory. Bubble-sort for instance is very easy to implement, if not the best performance.

I don't know anything about this firmware or the structures used so maybe there is some other limitation that makes simple sorting not possible? If so maybe that's another area that could be optimized. Is any of this code available to look at? Maybe from the NanoVNA?

Hi Phil,

OK sounds good, PM me if you wish to discuss in greater detail. It will save cluttering up the forum.
