Three-Day Conference(Friday, Saturday, Sunday)
This is a must attend conference for technically inclined amateurs.
Now, more than ever, Amateur Radio needs this great meeting of the minds
to demonstrate a continued need for our current frequency allocations by
pushing forward and documenting our achievements. The ARRL and TAPR
Digital Communications Conference is the best way to record our
accomplishments and challenge each other to do more.
Just review past DCC proceedings to the see the depth of topics presented since 1981.
The ARRL and TAPR Digital Communications Conference is for all levels
of technical experience, not just for the expert. Not only is the
conference technically stimulating, it is a weekend of fun for all who
have more than a casual interest in any aspect of amateur digital
electronics and communications.
Each year the conferences invites top amateurs in the field to speak. Past speakers have included Geoff Baehr, N6LXA, Chief Network Officer of Sun Microsystems, Dale Hatfield, W0IFO, Chief of the FCC's Office of Engineering and Technology, Yutaka Sakurai, JF1LZQ, Vice President of Japan's Packet Radio User's Group, and Ken Kaplan, N0GZ, who wrote the OS/9 operating system.
This year's banquet speaker is:
Gerald Youngblood, K5SDR
His topic will be "Accidental Company", the making of Flex Radio.
This year's Sunday seminar is by
Chris Testa, KD2BMH
Introduction to SoC FPGA Programming for Mixed Signal Systems
Abstract: The latest generation of Field Programmable Gate Arrays (FPGAs) offer an unprecedented level of integration, combining a full ARM processor with standard peripherals like USB and Ethernet on the same die as customizable logic. These Systems-on-a-Chip (or SoC's) are available from all major FPGA vendors, and they allow the hobbyist to hack together a state-of-the-art embedded system with all of the bells and whistles of a modern smartphone, all with minimal effort.
In this seminar we'll cover the structure of these SoC FPGA's, from a high level discussion, down to the nitty gritty of designing and interfacing custom logic to meet your needs. We'll start with the basics like state machines, and end with integrating and processing real-world, mixed signals. The perfect setup to start you off on your next software radio or robotics project. This is not a vendor tool tutorial - all of the tools used are 100% Open Source. You'll go home with a set of working example projects that simulate the full concert of an embedded SoC FPGA, ready for your imagination to run wild.
What do you need to bring? . The computer labs are optional and will be held during the 30 minute breaks. If you would like to follow along, the best case scenario is to install Ubuntu or Debian on your laptop prior to coming to the seminar. Or we will provide you with a .1-line installer script. at the seminar for Ubuntu/Debian that can be adapted for th.s seminar.
Each year at the DCC a separate (and lockable) room is
provided for people to bring and show off their latest projects. Tables
and power will be provided. Bring your equipment and display for all to
see, learn, and ask questions about. Be sure to bring a small sign and/or
flyer naming and describing your project.
Meals are not included in the registration. Two lunches and the banquet are available for purchase at the time of registration. Since numbers must be provided in advance to the hotel, trying to buy meal tickets after arrival at the conference does cause difficulties.
Conference presentations, meetings, and seminars will be held at the
Austin Marriott South, Austin, TX.
It is highly recommended that you book your room prior to arriving.
A block of rooms at the special DCC room rate of $105.00 single/double.
This special rate is good until 5:00 PM CDT , Wednesday, August 13, 2014. after that you will pay the regular room rate..
To book your room, use the reservation link below or call the hotel directly (phone numbers below) and mention the group code DCC when making reservations. (note: the group code will show as TAPTAPA on the web reservation form)
Be sure to book your rooms early!
