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

Hi Stefan,

Hi,Stefan:
recently,whtn I study the drs.cpp code ,I found that the buffer[1] is char but the addr and the base_addr are all unsigned int,isn't
there any problem that the addr may be cut off to 8 bits? Also ,I found that the data fpga recieved from the usb is 16 bits,so how can fpga get the true |

The FPGA is very small, so it only has an address space of 256 bytes. Look at the definition in DRS.cpp
#define USB_CTRL_OFFSET
0x00 /* all registers 32 bit */ |

Hi Stefan:
I'm still confused that althought the 8 bits buffer is enough,the FPGA receive the command through the uc_data_i register which is
16 bits wides.As we can see in the firmware, the locbus_addr is 32 bits wides. Does it means the locbus_addr[31:8] are always '0' because the address |

Sun May 6 11:45:09 2018, Stefan Ritt, confusion about the description in drs.cpp
|
The locbus_addr is indeed 32 bits wide, since the firmware was originally derived from some firmware running in a VME crate, and the VME bus has 32 bits
or addressing. So you will still find some "historic" remnants from that era. In the USB firmware, lcobus_addr[32:8] is always zero. Sorry for
the confusuion. |

Hi,
Is there a straightforward way to convert the xml file format into the binary format? I have some runs taken mistakenly with
xml. |

I have problems with driver installation on windows 8.1 (software version 5.03). I have sen that that has been an issue before (driver signing)
and I would like to know if this has been solved. We run several DRS4 evaluation boards on different PCs all running Win7 without any problems.
Therefore we are almost confident that it is related to Win 8.1. Thanks. |

Are there plans to add the drs software to github? (asking because I have users @ethz.ch that want to use it on debian,
thus I'm creating official debian packages of it, if license allows so, but talking to upstream (the developers) would be
much easier on github (or irc) than on this "DRS4 Discussion Forum".

Not github, but bitbucket: https://bitbucket.org/ritt/drs4eb/src/master/
But development kind of stalled, so there will be updates only in case of severe bugs, which are kind of gone after 10 years now.

Hello,
I compiled base file for drs system (DRS.cpp) to root framework (root.cern.ch) as dynamic library DRS.so. It can be used for building many
kind of applications under the root system. I applied it for older version of root 5.28 and for latest version 6.02 too. |

Dear all,
I have a question about the function that drs4 can perform.
Is there any function in drs4 that is analogous to that of "persistence display" in oscilloscope?? (accumulating pulses) |
|
Wed Jan 20 17:37:51 2021, Stefan Ritt, drs4 persistence

The chip itself can only sample a single waveform, that must be done in the attached software. The current DRSOscilloscope software coming with the evaluation
board has not yet implemented that, but if you write your own software you can do so.

Hej everyone!
I have some questions regarding what happens to some DRS registers in some scenarios:
