Re: DC17 Badge Pre-Release Information
I don't really have a lot of experience with hardware, and this confused me a bit. I thought standard TTL was 5 volts, not 3, and wikipedia claims that USB is actually native 3V. FTDI's site was actually advertising a TTL to USB shifter, which is what started my suspicion.However, this year will require a bit more soldering skill to get it up and running and you will need a level shifter to convert the 3V TTL-level serial of the badge to RS232 or USB level.
So, is a level shifter necessary for USB communication, or just interfacing with 5V components?
edit:
Reading the product page more closely, I find:
Is the cable just needed for converting USB signals to RS232?This version of FTDI's USB to TTL serial adapter cables has it's I/O pins configured to operate at 3.3V levels.Last edited by YenTheFirst; July 21, 2009, 19:06.It's not stupid, it's advanced.Comment

Re: DC17 Badge Pre-Release Information
It looks a little more involved. Please spend some time in the HHV I am sure you will get your questions answered.
The cable has one of these chips in it.

The FT232R is a USB to serial UART
interface with the following advanced
features:
• Single chip USB to asynchronous serial data
transfer interface.
• Entire USB protocol handled on the chip. No
USB specific firmware programming required.

Re: DC17 Badge Pre-Release Information
Just think "Iron Chef America"! What you may say? Well, when one competes in the "Iron Chef" cooking challenge each chef already has an idea of all the courses to cook. They just do not know the secret ingredient.
So, with the badge hacking contest. You know the processor. What do you want it to do? There is a DSP, do you want a DTMF dialer?
I think the team that will win the Black Badge this year will already have a plan for what they want the badge to do even before they see the badge.
We know we have a chip that is both a DSP and a micro controller. So. you can already start brainstorming. We know last year the badge was built to have interactivity with other badges. So, maybe this years badge maybe the same.
Teams that come with a base design and parts are the teams that will win!Comment

Re: DC17 Badge Pre-Release Information
Also SparkFun has a great little 3.3v FTDI board which is great for doing chip reprogramming, and drivers are available for Linux / OS X / Windows:

They have >300 in stock, which is good. I use them all the time for USB programming of AVR based boards, and they are a generic USB->3.3V TTL serial device.Comment

Re: DC17 Badge Pre-Release Information
cheap source of the level converters are the nokia DKU-5's etc, 3.3v, you can find them for a few $.
just make sure you get the right ones, some are pure usb, some 5v, some are level converters ( the ones with the longer usb plug are usually the right ones)- Null Space LabsComment

Re: DC17 Badge Pre-Release Information
ups had it out for delivery for 3 days, finally got here though with our current weather iw as expecting melted cd's. Picked it up from freescale directly.

Re: DC17 Badge Pre-Release Information
i've always had a bit of a love/hate relationship with codewarrior and it seemingly continues!
So FYI for me its very unstable with windows 7 32b 7100, 4 times out of 5 it'll crash on startup, shutdown or in use, and if you install it in Virtual XP, it's not licensed to run in a 'terminal server'
It also doesn't work with 64 bit windows, it is said to be supported on Vista 32, i did check it in the various compatibility modes.
Time to install Vista 32 then, and give that a shuftie.- Null Space LabsComment

Re: DC17 Badge Pre-Release Information
just an FYI
The hardware hacking kits this year will INCLUDE a level shifter that will work ...
But the kits will likely sell out on Thursday.

Re: DC17 Badge Pre-Release Information
Ok, I think I have made some good progress with CodeWarrior and Processor Expert.
I am very new to this whole DSP + Microcontroller programming. Or a DSM :)
This tutorial really helped me understand CodeWarrior and Processor Expert.

Take a look at all the "Beans" we have to work with. There is even a OS. I do not think that "MicroC_OS_II" will be used on the badge because the source needs to be downloaded and it may even need a license.
There are still a lot of telephone type beans. Just a guess. Oh, and even a DSP for 3DES and DES. Cool chip.Comment

Re: DC17 Badge Pre-Release Information
How will the contest be judged? Is it a largely subjective thing, where it's just the design you like best, or is it something a little more objective, like how "evil" the badge is? Also, for exceedingly evil badges, when a full demonstration would be a flagrant violation of the law, is it enough just to demonstrate that it WOULD work? ;)Comment

Re: DC17 Badge Pre-Release Information
The contest is completely subjective (I'm the only judge and I don't accept bribes...yet) and is based on how cool, unique, mischievous, interesting, and technically competent the hack is. :)
See previous contests and results here to get an idea of the caliber of entry:
