FMC Projects: FMC projects & co. presented in FOSDEM 2012

Added by Javier Serrano about 17 hours ago

A bunch of us attended FOSDEM 2012 in Brussels, Belgium. Presentations included the FMC kit, Self-Describing Wishbone and the ZIO software framework for Linux software support of IO gear.

FMC TDC 1ns 5cha: 02-02-2012: V2 design ready

Added by Erik van der Bij 6 days ago

Based on the experience with the V1 prototype, nine Issues were found. Corrections have been made to the schematics and PCB layout and these will be reviewed on 7 February. After this CERN's design office will generate the final production files.
The firmware VHDL code is under thorough review and production test software has to be written. This work should be ready by the end of the summer.

Simple VME FMC Carrier (SVEC): Schematics review held

Added by Erik van der Bij 6 days ago

Three months after CERN placed the order for the design, we received the schematics for the Simple VME FMC Carrier (SVEC). One week later the first design review came up with suggestions to make the design even simpler and more compatible to the SPEC design that it should follow as closely as possible. The compatibility will make that firmware developed for the SPEC will be easy to port to the SVEC.

CERN Open Hardware Licence: 31-01-2012: OHL being discussed on LWN.net

Added by Erik van der Bij 8 days ago

LWN.net is a reader-supported news site dedicated to producing the best coverage from within the Linux and free software development communities.
In response to CERN's Call for Comments LWN.net currently discusses improvements to the CERN OHL licence.

Note that cernohl@ohwr.org is the official mailing list where the CERN Open Hardware Licence is discussed and that is guaranteed to be followed by the relevant people. Fortunately the most interesting messages from LWN.net are transmitted to this official mailing list.

FMC ADC 200k 16b 11cha: 200 ksps ADC documented

Added by Erik van der Bij 9 days ago

Ross Millar, student at the University of Glasgow, has worked for six months at CERN to debug the 200 ksps ADC, write firmware for it and develop a new version of the circuit board. He wrote an extensive report about his work.
Before this ADC can be produced in quantity, the final design has to be verified and the firmware needs to be re-aligned with the firmware of the 100 MSPS ADC so it can more easily be maintained and driver code can be more easily shared.
We needed to put the project on hold because of lack of manpower and the availability of a commercial and proprietary alternative for CERN's applications.

OHR Support: OHWR MAINTENANCE ON 2011-01-30 (MONDAY) 08:30 CEST

Added by Enrique García 12 days ago

Hello everyone,

Next morning we'll be doing some server updates on the OHWR main server.

As usual, the maintenance job will happen next monday at 08:30 CEST. Our estimation is that it will take about 30 minutes to complete.

All of the ohwr.org subdomains & services (including svn.ohwr.org, lists.ohwr.org, and the git repositories) will be interrupted for a short while during that interval.

We apologize for any inconvenience this could cause.

Best regards,

The OHR-support Team

White Rabbit: White Rabbit presented in CERN's fieldbus WG

WR was successfully presented in CERN's fieldbus working group. You can find the slides and some pictures, including the latest and greatest 18-port switch box at http://www.ohwr.org/documents/148

OHR Meta Project: 23-01-2012: Creotech produces 4 CERN OHR designs

Added by Erik van der Bij 16 days ago

The Polish company Creotech, that was already involved in the design of the SPEC PCIexpress FMC carrier, has decided to commercialise three Open Hardware designs that were initiated by CERN: SPEC, FMC ADC 100M 14b 4cha, the FMC DEL 1ns 4cha and the FMC DIO 5ch TTL a.
The same company has also created modified versions of the CERN's SPEC board for dedicated applications of its clients. These designs will soon be published on the ohr site as Open Hardware designs.

CERN Open Hardware Licence: 18-01-2012: Call for Comments on OHL v1.2

Subject: CERN OHL v.1.2

Hi,

Thanks to all the feedback we have received on the CERN OHL v.1.1, we have made a few revisions and are now submitting the CERN OHL v.1.2 for comments and feedback (see text of the licence at http://www.ohwr.org/documents/144). The main changes were introduced in article 3 of the licence.
One point in particular is still under discussion and concerns article 3.3(e) – attempting to send modifications to the Licensors whose design was modified and those who requested it. On the one hand questions of practicalities arise – does every minor modification/debugging need to be sent to everyone? – while on the other it may be perceived as a fair return, for contributors, to be notified of modifications that were made. Your input and suggestions on this point are most welcome!

Another point which we would like also to consider is the question of compatibility with other licences.
David Mellis (of the Arduino team)had made the following suggestion:
"what about the possibility of aligning this license with the TAPR one, so that they could, for example, serve as localized versions of the same license? The licenses seem very similar in intent and approach (at least to a legally-naive reader) - it would be great if we didn't have to worry about choosing between them. At a minimum, maybe there's a way to allow for compatibility between them (i.e. the ability to combine TAPR OHL-licensed documentation with CERN OHL-licensed documentation)?

We hope to make the CERN OHL v.1.2 practical to use for anyone, so let us know if you think there are other points that could be improved as well.

Best regards,
Myriam

CERN Open Hardware Licence: 11-01-2012: CERN's Director General cites OHL

Added by Erik van der Bij 23 days ago

In his New Year's presentation 2012 to all CERN's personnel, CERN Director General Rolf Heuer devoted one slide on the CERN Open Hardware Licence.
The slide reads:


Implementing new IP schemes
to bridge the gap between CERN and society

CERN Open Hardware Licence

A legal framework to facilitate knowledge exchange
across the electronic design community.
Version 1.1 of the Licence was issued in July 2011.

In the spirit of knowledge and technology dissemination,
the CERN OHL was created to govern the use, copying,
modification and distribution of hardware design documentation,
and the manufacture and distribution of products

Knowledge Transfer | Accelerating Innovation
