DRS Oscilloscope for Raspberry Pi and Mac OSX 10.8

I made a pre-compiled package for Mac OSX 10.8 (Mountain Lion), so one should be able to install the DRS Oscilloscope software with one mouse click on a recent Mac.

The Makefile in the tar ball now also supports OSX 10.8, so one could even compile it from the sources on a Mac, after libusb-1.0 and wxWidgets have been installed. That might then also work on older versions of OSX.

In addition, the software has been adaptes so that it compiles nicely on a Raspberry Pi (http://www.raspberrypi.org), a screenshot has been attached. Together with a Raspberry Pi and an old screen, the evaluation board is one of the cheapest available oscilloscopes.

Question for using Multi board

Hi.

I have 2 DRS4 evaluation V4 boards, and I want to use these 2 board to multi board DAQ system for 4 ch vs 4 ch DAQ.

But there is no option for multi board use. I just only find the multi board trigger mode check button on DRS4 Oscilloscope program, but I couldn`t check.

Is there any method to use multi board?

Best regards.

Gyuhee.

This mode is not yet implemented in firmware. Maybe I find some time towards the end of this year to add this. At the moment, you have to build and external trigger to synchronize the two boards. There are also 16-channel boards on the market where you would not need a multi-board mode. Just Google for "DT5742".

/Stefan

Thanks Stefan.

I will build external trigger system.

I have some question according to GetWave function. In drs_exam.cpp simple GetWave(0,0,wave_array[]) etc...is used. Is there primary (cell) calibration, secondary calibration (Readout) and remove Spikes used, as in DRS Oscilloscope application?

Yes, yes, no. To get spike removals, you need the function RemoveSpikes from Osci.cpp in the DRSOsc project.

Hi,

We are using drs4 board, but oscilloscope app will somehow stop to work if we config trigger into "or and", When I look into the drs4 firmware file drs4_eval3_app.vhd, I couldn't find the trigger_config value assignment which is mentioned at(#7 offset 0x1E from 31 downto 16) in manual_version 4.

could you help me find this trigger_config access point?

thanks

Hongwei

The "and" in the trigger section means now "coincidence". So the V4 board can trigger on a coincidence between two or more channels. If there is no pulse at the same time on the coincidence channels, the board will of course not trigger. The according firmware was introduced in V4, so please look at drs4_eval4_app.vhd (not eval3).

I just realized that the V4 firmware might be missing in the distribution, so I have attached it here. Look for drs_ctl_trigger_config.

Best regards,

Stefan

Ah, great, that helps, Thank you!

Hongwei

By the way, will there be a drs4_eval4.vhd as well?

Here it is.

Thanks. have a good day

I just realized that the V4 firmware might be missing in the distribution, so I have attached it here. Look for drs_ctl_trigger_config.

Best regards,

Ah, great, that helps, Thank you!

By the way, will there be a drs4_eval4.vhd as well?

I just realized that the V4 firmware might be missing in the distribution, so I have attached it here. Look for drs_ctl_trigger_config.

Best regards,

Stefan

Ah, great, that helps, Thank you!

Hi,

could you help me find this trigger_config access point? Or is there any drs4_eval4_app.vhd missing in the source files?

Hi,

Our group had previously heard that a "DRS-5.0" might be on the horizon and that it may have ethernet capabilities as well as 16-input channels (we heard this when ordering the DRS-4). Is this still in the works and accurate information? If so, is there a rough estimate to the "release date?"

Thanks for your time,

Zach Miller

You mix up two things: The DRS5 chip is a new device with improved samling speed (10 GSPS) and lower dead time. This chip might come in 2-3 years. The 16-input board you mentioned is a DAQ board based on the DRS4 chip. This board well be operational beginning of 2013 as a prototype. It is not clear however at this point in which way this board will be made available for public. Maybe we will license this to industry. The design is however pretty much defined: 16 channels with gain 0.1-100, 1 GHz Bandwidth, Gigabit Ethernet output, and multi-board capabilities. Trigger on each channel with logical combinations. 80 MSPS continuous sampling (in addition to the DRS4 sampling). Each channel can be biased 0-210 V for SiPMT or APD power. A 19" 3 HE crate will host 16 boards with 256 channels.

/Stefan

Thanks, Stefan. That was the information we were looking for.

Cheers.

DRS-4.0.0 DOScreen.cpp

Hi,

I found an old thread regarding a fix for DOScreen.cpp for DRS-3.1.0, that fixes an "ambiguous overload problem." Currently when I attempt to build the drs-4.0.0, I get this similar error:

src/DOScreen.cpp:332:39: error: call of overloaded ‘Append(int)’ is ambiguous

This section of code is different than what the previous thread was correcting, and though I attempted to apply the logic of the old thread, I haven't fixed this yet.

The following is the code for that section:

-----

329 for (int i=0 ; i<5 ; i++)
330       if (tc & (1<<(i+8))) {
331            if (i < 4)
332              wxst1.Append(wxT('1'+i));
333            else
334              wxst1.Append(wxT('E'));
335           wxst1.Append(wxT('&'));
336        }
337      if (wxst1.Length() > 0)
338         wxst1 = wxst1.Left(wxst1.Length()-1);
339      wxst1.Append(wxT(')'));

------

I've attempted a few fixes, but unfortunately, my understanding of the code is not great, and I haven't managed to fix this yet. Any help would be appreciated.

Thanks,

Zach Miller

Just put (char) in front of wxT(...), like

if (tc > 0) {

wxString wxst1, wxst2;

wxst1.Append((char)wxT('('));

for (int i=0 ; i<5 ; i++)

if (tc & (1<<i)) {

if (i < 4)

wxst1.Append((char) (wxT('1'+i)));

else

wxst1.Append((char) wxT('E'));

wxst1.Append((char) wxT('|'));

}

for (int i=0 ; i<5 ; i++)

if (tc & (1<<(i+8))) {

if (i < 4)

wxst1.Append((char) (wxT('1'+i)));

else

wxst1.Append((char) wxT('E'));

wxst1.Append((char) wxT('&'));

}

if (wxst1.Length() > 0)

wxst1 = wxst1.Left(wxst1.Length()-1);

wxst1.Append((char) wxT(')'));

Hi Stefan,

Thanks for the response. I have tried that and it fixes all the lines except the ones that have:

wxst1.Append((char) (wxT('1'+i)));

Those lines still don't compile for me. I've also tried: wxst1.Append((char) (wxT('1'+(char)i))); and wxst1.Append((char) (wxT((char)'1'+i))); as well as a few other combinations of (char) and Append.

I get the same error of: "Call of overloaded "Append(int)" is ambiguous."

Any other help would be greatly appreciated. Thanks!

-Zach

wxst1.Append((char) (wxT((char)('1'+i)))); maybe ???

Aha!

wxst1.Append((char) (wxT('1'+i)));

That one actually works as you initially thought, but you my editor was being picky of (char)wxt... instead of (char) (wxt....). For some reason, it has to have the extra set of parentheses around wxt(). Thank You!
