SainSmart DDS120 & DDS140 USB Oscilloscope
doctormord:
I would guess, it's available at the expansion header.

I found out that the sdcc compiler doesn't support dual data pointers. Dual DPTR gives a huge performance boost, so I'm unsure if I want to base a new firmware on it.
Other than that, I got fosphor working, by telling my shell to
--- Code: ---export LD_LIBRARY_PATH=/usr/lib/fglrx
--- End code ---
before compiling. Proprietary code was needed. My GPU should be able to cope with 220MS/s, according to some benchmarks made by fosphor people. From this evidence it appears that direct sampling of an oscilloscope signal is achievable. OpenCL/OpenGL interop opens up some really interesting use cases.

I'm wrong again. There are some more command codes :(
doctormord:
Someone asked for demo-code or "SDK"?
Its in here:
http://m5.img.dxcdn.com/CDDriver/CD/sku.271544.rar
The included publicDLL.dll only supports "GetFre; GetVolt; Setpara".., the programmcode refers to "getData".. |O
--- Quote ---The publicDLL.dll and demo.exe, placed in the same directory as the oscilloscope software,
Oscilloscope software at run time will be part of the measurement data is written DLL, while demo.exe simultaneously read and display these data.
Provides demo.exe VC source code, users can refer to write their own applications.

Edit:
Seems like the software is also for the BM204 (beside BM102/BM104). The BM204 got an external trigger input:

Edit2:
The provided demo.exe is working when copied to the DDS120-Software-Directory. (DDS120.exe and Channel 1 needs to be running)
Source-Code is avail here:
"Oscillograph\Demo\VCSource"
Seems like the demo.exe is only talking to the software, not to the scope directly.
My Driver-CD is done at 20140606 with manual from 20140522.
If someone needs, there a download-link from my amazon-seller. (Sent via mail)

:palm:
So that's why I couldn't get it to work.
It just seems to incredibly useless. What could have been the point of this?
