Hi Stefan,

Thank you for pointing me to the document. Does it apply only to version 5 of the board or can it be applied also to version 4 (which is the one I have)?

Dmitry

 Hi,

I am getting the following compilation error when trying to compile version 5.0.2 software:

---------------------------------------------------------------------------------------------

Full error report:

g++ -g -O2 -Wall -Wuninitialized -fno-strict-aliasing -Iinclude -I/usr/local/include -DOS_LINUX -DHAVE_USB -DHAVE_LIBUSB10 -DUSE_DRS_MUTEX -I/usr/lib64/wx/include/gtk

Hi Stefan,

Unfortunately that did not work and from suggestions in the error I do see a good solution:

----------------------------

src/DOFrame.cpp: In member function ‘void DOFrame::LoadConfig(char*, int)’:

src/DOFrame.cpp:617:25: error: call of overloaded ‘wxString(char [1024])’ is ambiguous

let me know if you see one.

Thank you,

Hi,

has anyone experienced a shutdown of the DRSosc.exe or DRScl.exe when executing a Timing Calibration? Also, when we add the command b->CalibrateTiming(NULL); to the drs_exam.cpp and run the exe, our program shuts down immediately and windows shows an error message (identical to DRSosc and DRScl).

Any help is appreciated.

Hi,

I'm trying to recompile the USB microcontroller firmware starting from the drs_eval.c file but I'm not able to get a .iic file close to the one provided with the eval board. It seems to me that this drs_eval.iic file does not match the drs_eval.c and drs_eval.hex files or that I'm doing something wrong. Could you please help or give me an explanation.

Thank you.

Stephane

 Thank you Stefan.

Would that be possible to get the corresponding drs_eval.c source file since I'm assuming the one provided with the eval board is not the right one?

Thank you.

Stephane

I'm very sorry to insist but if I take the .hex of the distribution, convert it to .iic using the hex2bix utility, and reprogram the board, I can't read the board correctly (invalid magic number read with drscl for instance). Also, when using the uVision2 project file you provide and compiling the drs_eval.c, I get the same result  (i.e. no way to generate a functional .iic file starting from the sources). So, either I'm doing something wrong (and I don't know what) or the drs_eval.c is not the correct one.

It works as expected.

Hi,

I'm currently working on a little DAQ system with four DRS evaluation boards. Do i need to apply any specific settings when using the clock in/out connectors for synchronization? I do not see anything like that in the drs_exam_multi example.

Any help would be greatly appreciated!

Best,

Simon

When running drsosc on a raspberry pi, it seems the exit doesn't seem to work at all.  This is true for the "exit" button on the window, or the file menu exit, or the "x" on the window.  I end up having to kill drsosc manually from the command line.  This wouldn't be such a bad thing except that it doesn't seem to store any settings when killed in this way.  I'm wondering if anyone else sees the same thing, or if there is a fix out there, before I go and delve into why.

Hi,

we want to run two instances of our little DRS DAQ program but obviously the first instance started always claims all DRS boards for itself and the other one exits with an error. The 2 boards used in the example below have the serial number # 2413 and #2414 and are v5 boards.

The first one:

mathes@ikauger5:~/src/DRS4/Cpp> ./drsdaq -b 2413
DRSController: found board with serial number #2413
DRSController: found board with serial number #2414
DRSController: using board with serial number #2413
CalibratedFrequency= 1.00721
====================================
DRS type:            DRS4
Board type:          9
Serial number:       2413
Firmware revision:   21260

...
And the second one:

mathes@ikauger5:~/src/DRS4/Cpp> ./drsdaq -b 2414
musb_open: usb_set_configuration() error -6
musb_open: Found USB device 0x04b4:0x1175 instance 0, but cannot initialize it: please check permissions on "/proc/bus/usb/1/7" and "/dev/bus/usb/1/7"
USB successfully scanned, but no boards found
...

How can our goal be achieved?

Thanks

Hi Stefan,

do you know how these numbers (400ps and 60ps) scale with the sampling rate? The manual says they are for 5GS/s, do they change with slower sampling?

Thanks and best regards,

Simon

Hi

I have a question about the function SetTriggerSource in the class DRSBoard (DRS.h/DRS.cpp)

In the implementation there is the following comment:

// Set trigger configuration

// OR 0=CH1, 1=CH2, 2=CH3, 3=CH4, 4=EXT

// AND 8=CH1, 9=CH2, 10=CH3, 11=CH4, 12=EXT

What does this exactly mean? I am assuming that this are the bits which are set?

e.g

source = 1 ==> CH1

source = 4352 = 0x1100 ==> CH1 and ext

How is the AND/Or logic implemented?

When i have:

source = 0x1803 (bit 12,11,1,0)

what is the right way to set the brackets to expalin the logic?

(EXT and CH4 ) or CH2 or CH1 ?

Hi,

I`m trying to calibrate my DRS4 evoluation board to an input range of 0-1V but it doesn`t work.

1) First I tried to calibrate it with the drsosc (version 5.0.3) Software. The -0.5V - 0.5V calibration works, but during the 0 - 1V calibration the Software crashes.

2) I also tried to calibrate the input range with a C++ DAQ Package (based on drs_exam). Here the code of the calibration:

    ....

    b->SetInputRange(0.) (Center at 0 V )

    b->CalibrateVolt(NULL);

   ....

   Calibration Works

   ....

   b->SetInputRange(0.5) (Center at 0.5 V )

   b->CalibrateVolt(NULL);

  ....

   Results in: Found 4096 stuck pixels on this board.

Did I do a mistake or is this a normal behaviour of the board? Also the board often crashes and I get a magic number 0000 after restarting the DAQ. Then the board needs to be restarted via pulling the plug. ( I ensured that I terminate the USB connection before I close the program with "delete drs"). Is there a possibility to avoid this error?

My OS: Ubuntu 14.04 LTS.

Ciao,

Julien

I also use Ubuntu 14.04 LTS and for my V3 borad I have to use drsosc 4.x or ealier to perform the calibration.

I'd like to be able to know which channel (0,1,2,3 or external) was responsible for the trigger.  DRSBoard::GetTriggerSource() seems to always return 1.  Is there a way to get this information?  Using the DRS4 evaluation board and software version 5.0.3.

Thanks,

Cosmin
