Iâm not sure I understand the numbers you quote 492k and 2G. The file you need to install is just APP1.hex (or APP2, APP3 if putting in different slots). This is a 183k file. The rest of the material in the zip is the source code etc.
You start up the DSO with the USB connected and left hand button pressed which puts it in download mode and then just copy the APP1.hex file across.
By the sound of it you may have the latest hardware with 8GB disc. You can check this by looking at drive properties when mounted. If so then this software may not be compatible with this yet as it was built for the previous models with 2GB discs. That is one area I am interested in sorting out. There is no harm in trying as you can restore the original software if you have its hex file.
I guess you are getting a HEX file that is bigger than what it is supposed to be(possibly rendered in HTML format). You should use the right-click save-as option to save the HEX file before you use. Check the HEX file size to be sure you got it correctly.
Three days ago I also got my DSO QUAD. It reports HW ver. 2.72 and the drive size in Win Explorer ist 8MB.
It took me a day to find out about this firmware stuff.
What works:
- Gabonator
- Pawn stuff
What doesnât work:
- APP_G251
- Wildcat 3
Both install, start and do a lot, but e.g. the time base setting is never displayed and
I canât fire up the CAL screen. Looking at the code this is wierd, as short/long/extra long
key presses are correctly processed but the cal routine ist probably never called as
one of the first things it would do is blank the screen, but that remains undisturbed.
Thanks to the Gabo package I could set up a dev environment on Win, rebuild his latest app version
and run it as APP4.
@tsipaki7
I find your SYS and APP versions posted somewhat surprizing as I understand the 8M hardware
requires SYS 1.60, mine has that. Also my APP is 1.10 and Iâd like to know what 2.53 is.
Try the wildcat3.zip file from the post above yours. If it unpacks with no error then the download is ok.
Then try one of the appX.hex files.
Warning! make sure you have the hex file for the stock firmware before you do anything!
I found that installing something as APP 2-4 often corrupts APP1.
Wilhelm
mr.django, I appear to be in the same boat. I have HW version 2.72 and got the errors you report with APP_251 and Wildcat 3. I was also not able to observe a signal from the signal generator.
Iâm going to try Gabonator and Pawn Stuff later and report back.
Is this âPawn Stuffâ? All I could find in a quick search was something called QuadPawn.

And just to confirm, this is Gabonator?

Re: issues with hardware 2.72:
The code I posted was not tested with and never meant to work with the newer HW2.72/SYS 1.60. File reads/writes
will likely fail with this version as cluster size used is different with the newer 8Mb drive it uses. One of the first things the
program does is read the config file, which will likely corrupt the menus, among other things, if not read properly.
Unfortunately, at this time, I donât have one of these later 8Mb version devices, so I canât test any possible
modifications to make it compatible. I just purchased another Quad (NOT from SEEED), but it turned out
to be a 2Mb version (with a sub-standard âcloneâ ADC that had to be replaced, I might add⌠Produced nothing
but garbage on one channel at the faster time bases) .
For those with the earlier version, hereâs a minor update, bug fix and performance improvement:
CHANGELOG TO VERSION W3.1:
-Fixed color background for FFT values being used from out of bounds array index, producing faint
blue background (or possibly something else if recompiled) instead of black. Also changed FFT
frequencies display to green to match channel D color (provides better visibility than red).
-Fixed inadequate buffer size being used under some conditions when using spectrograph function.
-Fixed a bug where meter readings of one channel would show up on another channel if it was turned
off and FFT turned on.
-Changed triggering selection logic to better integrate with FFT when not displaying trace.
When all channels are off, triggering will be set to FFT displayed channel. Also, trigger selection
shortcut will acknowledge FFT channels, if on, when switching trigger source, rather than channel D.
-Changed V/div shortcut: now if selection is already on V/div, will toggle channel on/off, rather than
going to other analog channelâs V/div and turning that one on, if off. Also if FFT is on with all
channels off, shortcut will go to the FFTâs channel V/div but will not turn it on (long press again
to toggle channel trace on/off if desired).
-Added V2 cursor = db in FFT mode, V2 cursor position added at top of screen. Helps calculate db
readings, particularly near bottom of screen.
-Changed graphics of FFT freq displays so peak trace can be clearly seen through them, providing
better visibility at top of screen.
-Changed most often called for background graphics refresh source from ROM constants to run time
loaded RAM arrays. Provides significant increase in frame refresh rate (specially in single frame
buffer mode) and reduction of ROM size allows program to still fit within 2 âslotsâ in spite of
increased size/complexity.
-Start/Stop will now pause spectrograph.
-Eliminated needless simultaneous drawing of hidden trace graphics while in spectrograph mode
(speeds up refresh).
-FFT summing mode now engages a bin earlier at the extreme left in the spectrum.
I just installed The Wildcat 3.1 app. (Hardware v2.6, SYS 1.50)
Thank you so much for this, Wildcat!!!
Itâs fantastic!
I just found one issue.
The frequency of the internal signal generator is 4 times higher than indicated.
The internal frequency counter and the FFT display the real frequency. e.g. with the signal gen set at 1 kHz the app displays 4 kHz.
I confirmed with another frequency counter and it also shows 4 kHz when the signal gen is set to 1kHz.
Any idea?
Sorry if this has been addressed before.

Markus
Are you using the modified SYS that was designed for the community app? That will cause that effect with the WIldcat APP which is designed to use the standard stock SYS.
So⌠is there -any- firmware out there that works with HW 2.72? Or am I now stuck with an albatross?
Thanks for your answer!
Good question :oops:
On my display it says SYS 1.50 SmTech 1.6
Could you please target me to the correct SYS?
Edit: just found everything on page 1 of this thread.
Now thatâs embarrassing
Ok found everything on the DSO wiki
Works like a charm now!
HW 2.72 with 8M?
HW 2.72 with 8M?
I have HW 2.6
Having a new Quad with 2.72/8M I am wondering what to do about the community software.
Just a thought - would there be any way to reformat the 8M as a 2M and reduce the cluster size so it would not have the software issues? Or, could a small partition be copied onto the device with something like Partition Master?
-Cory
I donât think one would be able to make the 8M device behave like a 2M one. Itâs not about partitioning, itâs more about the fundamental hardware block size used when the device erases and writes new data. That means the routines that do writing have larger buffers.
I think the most fruitful approach is to use the SYS 1.60 which supports the 8M device and then adjust the apps to be compatible with this. The calls made to the SYS are pretty much the same with the main differences being in the memory allocation, so it should be relatively straightforward. This is also evidenced by the gabonator app which largely works with 1.6 except for storing data. I did start to look a this as a family member has a 8M model whereas mine is 2M, but have not had much time to pursue this further recently.
The 2.72 / 8M issues seem to be fixed, please see the last upload in this thread: <LINK_TEXT text=âhttp://www.seeedstudio.com/forum/viewto ⌠187#p19187â>http://www.seeedstudio.com/forum/viewtopic.php?f=26&t=5128&p=19187#p19187</LINK_TEXT>
New update:
Tentative support for 8MB devices. Integrated bobtideyâs mods. Note that this has not been tested
on other than 2MB units at this time.
Added persistence and map modes, BMP load, and 30db extra gain to all FFT functions.
Updated spectrograph and XY modes + many minor improvements and bug fixes. See
changelog in README.TXT for complete list and how to use these. Program still fits
within 2 slots.
Persistence mode of RF eye pattern
in RAW data mode
Persistence mode of a video signal
in NORMAL data mode
30db additional FFT gain with
auto scaling
Voice print of person speaking
MAP mode of video frame
XY display of stationary pattern
in persistence mode
I tried this latest on my 8MB 2.72 with 1.6. It seems to work though I donât understand how to operate it. After bringing up the meters on the right, are you able to change what is displayed as in the original app?
Also, I assumed, maybe incorrectly, that app1, app2, app3 refers to the slot residency? I tried that and it looks like they boot in the correct slot but I get a blank screen.
Anyway, I applaud what everyone has coded and love the little device. I wanted something for on my desk as sometimes the DDS freq generators and other equipment I have wonât start and I canât figure out what is going on without a scope. After purchasing this little unit, I also bought a larger inexpensive DSO as well so it was âscope weekâ at my house. Been using an oldy but goody 300mhz tek 2465 for years which had a ton of functions with cursors, etc, but no storage.
So please keep up the good work. I would love to be able to boot wildcat from 2 or 3 keeping the original in 1. I have gabonatorâs code in 4 which I like as well.
Jerry.
after installing the wildcat version and reinstalling the original factory app, I can no longer install the wildcat. It installs ok with .rdy message, but boots to a blank screen.
Any ideas?
App1, app2, etc do refer to slot residency. However, most apps, including mine and the originals occupy 2 slots.
So if, for example you have the original in slot 1, adding another version in slot 2 wipes off the last half of the one
installed in slot 1. Likewise, installing in slot 3 wipes off whatever program is in slot 4. The gabonator app installed
in slot 4 I believe adds the rest of the code in some undocumented part of the ROM. This needs to be kept in mind
when adding programs so they donât overlap and destroy each other and kind of limits it to only 2 programs unless
2 of them can fit in only 1 slot each.
There has been some effort to rewrite the code to all these apps so only the first part of each of the programs fit in 1 slot
only, the rest to the aforementioned undocumented area. However this was only compatible with the older 2M devices.
The meters in my version can be changed like the original app, but the controls to do so may be different. While the
first âpageâ showing displays for both ChA and ChB canât be changed, the 4 remaining pages, each set up for one
of the channels can be changed to any relevant meter with source from any channel, but only until the page is changed.
Change pages with long press left toggle center. To change the meter items or source, long press right toggle center,
this will change the focus (blinking) to the meters. Use the right toggle to change between meters and the left toggle to
change the meter item itself (Vdc, Frq, etc). With a meter highlighted (blinking) short press button 4 to cycle between the
different channels as the source (Item will change to the channelâs color). Note that voltage meters are not available for the
digital channels. Keep in mind what while you can cycle between small, large and no meters without changing the selected
items, changing pages will return the pages to their default settings.
Custom meter settings can be saved by saving the entire configuration to a different config file, but only 1 page can be
saved (the one showing), since changing between pages restores defaults. When recalled, the custom settings will be
restored. My version allows 9 additional config files to be saved/restored. Hold button 3 down to access config save,
then if desired, change file number with left toggle. Config #0 is the boot up file. In order for all this to work, 9 extra
config files MUST already be on the deviceâs flash drive as the program will only save them if a file already exists.
This was done for compatibility with older devices which had systems that corrupted files. Copying these files and
putting them early in the file allocation table prevented the corruption. The 8Mb devices I believe fixed the corruption
problem, as did the Alterbios add-on for the 2Mb devices. Simply copy 9 instances of the xxxxx.WPT file with a
Windows machine, then rename them CONF001.CFG to CONF009.CFG.
For further info on operation, check out the changelogs and other info in the readme.txt enclosed in the archive.
A brief description on how to use the different functions is included. Holding down button 1 on the device will show
a chart of button functions. Iâve started to write a comprehensive âuserâs manualâ for my version. When I can find the
time to finish it, I will post it, along with some likely further updates (finishing up an additional log amplitude screen
option for the FFT function). The program is getting a bit complex, hopefully this will be of help.
wildcat, thanks, all that above really helps.
Why do you think it wonât install? If I use app1 and have nothing in #2, I still get a blank screen when I load your program. It worked the first time. It is almost like it is stuck in standby mode???
Now that I know how to change the meter pages I would like to install it in slot 1.
Thanks.
