DSO203 GCC APP - Community Edition (2.51+SmTech1.8+Fixes)

[alienrelics]

So... is there -any- firmware out there that works with HW 2.72? Or am I now stuck with an albatross?

I just installed The Wildcat 3.1 app. (Hardware v2.6, SYS 1.50)
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.

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.

Thanks for your answer!
Good question
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 that's 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

[cory.play]

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?

I don't think one would be able to make the 8M device behave like a 2M one. It's not about partitioning, it's 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: http://www.seeedstudio.com/forum/viewto ... 187#p19187

New update:

Tentative support for 8MB devices. Integrated bobtidey's 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 don't 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 won't start and I can't 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 'scope week' 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 gabonator's code in 4 which I like as well.
