Hi Stefan,

That's fine for me. I thought it might be interesting for others as well..

Yes of course no problem.

You can download via github https://github.com/veloxid/DRS4-v5-shared and I also put it in the attachment.

It's tested with Ubuntu, Fedora and RHEL.

For mac OSX one needs to create a dylib out of the so file.

Hi

Did you copy the udev rule 41-drs.rules into /etc/udev/rules.d/ ?

Which operating system are you using?

Hi,

I am trying to understand some details about the timing calibration.

We wrote our own code but we more or less use the ideas of the Oscilloscope class.

In the binary file writing of in the function Osci.cpp::SaveWaveforms() (line 924ff)

the following code is executed:

if (m_waveDepth == 2048) {
    t = (tcal[j]+tcal[j+1])/2;
    j++;
} else
    t = tcal[j];

I do not understand the averaging of the to adjacent calibration constants. Could you explain this? Do one have two measurements?

Cheers

How to configure DRS oscilloscope for the oscillations with an amplitude greater than the value of the exposed
in the trigger (internal). 

Can I adjust the internal trigger DRS oscilloscope for signal extraction 0.5 volts (for example) from any of the four channels. In our case, there is a lot of noise with low amplitude, which must be removed during the registration. We need to record the individual pulses of higher amplitude than the noise. So we want to use the internal trigger DRS oscilloscope to cut this noise by setting up its threshold amplitude noise.

    That's it? Thank you for your comprehensive answer.

Hello everybody!

After some times i init my board, or if i stop the program during the acquisition, i get the error message "Invalid magic 0000". The only way i can solve this problem is to physically disconnect and plug in again the USB cable.

What's the point? Is there a bash command / code i could use to reset it?

Thank you very much

Hello, thanks for your answer. Unluckily if i try to reset in this way it keeps hanging

I also tried with sudo tee /sys/bus/usb/drivers/usb/unbind and binding again; same thing happens. It seems the board needs to be reset when this happens. Is there a way to do that - to reset the board instead of usb?

Thank you

Hello,

is it possible to set a completely negative input range like -1 to 0 or -0.95 to 0.05 ?

Thank you

Hello there,

is it possible to setup trigger in double AND configuration (a pair in and or other pair in and). 

eg (CH 1 AND CH 2 ) OR ( CH 3 AND CH4)

Thank you

Hi,

I would like to use the DRS4 with my macbook pro running osx 10.6.8.
I have installed the wxWidgets and the libusb-1.0 libraries and I am using the Linux code vers. 4.0.1. After
compilation, the following errors come out:

ld: warning: in musbstd.o, file was built for unsupported file format which is not the architecture being linked
(i386)
ld: warning: in mxml.o, file was built for unsupported file format which is not the architecture being linked (i386)
....
....
ld: warning: in main.o, file was built for unsupported file format which is not the architecture being linked (i386)
Undefined symbols:
  "_main", referenced from:
      start in crt1.10.6.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
make: *** [drsosc] Error 1


Do you have any idea on how to solve the problem ?? or maybe do you have a package working with osx 10.6 ? I
remember to have seen, long time ago, a package that could work with 10.6 (or 10.5 ?), but I cannot find it now
(but maybe I remember wrong).

Thanks for any help,

Enrico

No, I have a MacBook Pro 2.8 GHz Intel Core 2 Duo.

Good point, but all libraries are already compiled to 32 bits, since the laptop is running at 32 bits. Unless you mean that I
have to convert to 64 bits, but this means to change all content of the PC, and I don't want to do this. Can the applications
run with 32 bits or do they need 64 ? 

Thanks,
Enrico

Good.

Ok, but I don't understand where is the point to correct. 64 bits do not appear explicitally (at least to me, who am not a drake of programming ...) 
neither in the Makefile neither in the (few) source files I have examined.

Thanks again,
Enrico

Hi Stefan,
   I made some progress. Understood what was wrong in the make phase. You have only to add the option -arch i386 in the CFLAGS line of the makefile.
Then the make is ok, it produces the 3 executables. drs_exam and drscl seem to work correctly. 
DRSOsc.app does not work as app, in the sense that if you click it, an error message comes saying "You can't use this version of the application DRSOsc.app with 
this version of Mac OS X. You have Mac OSX 10.6.8. The application requires Mac OS X 10.7 or later. "
If you execute drsosc from the terminal, the graphical window pops up, the waveform is displayed, but you don't have access to the graphical interface, no button works, you can't do
anything. To quit the app, you have to kill it from the terminal with the kill command.
But anyway is a progress with respect to yestarday.
Any idea/suggestion to overcome the above problems ? I thought it is a problem with the graphical library (xwWidgets) but I have checked it, it's ok, I have also reinstalled it
(release 2.8.12_3) but nothing changed.

PS. the chip test output (done with the drscl ) is the following (see below). Is it normal or what ? THANKS.

Hi Stefan,
yes, the makefile has already the recipe to create the app. For OSX 10.6 a obvious modification must be done in the info.plist file. Then everything goes right. Now I have the DRSOsc application
running on my mac with 10.6.
Thanks for the help.
Best regards,
Enrico
