Updated: I added information about the AVR dev platform in the second post.

Hey Luke,

do you think a combination of the VNC2-32L1B and the Atmega 328 would solve the problem getting USB on that "baby" The VNC2-32L1B is otg compatibel an would be the right choice. Is the Atmega328 strong enough to handle that? What do you think?

Hi Achim,
I am not sure what you mean, can you explain it in more detail?  The VNC2 does not need a microcontroller because it has a built in programmable 16-bit uC with free IDE.  So it is the best of both, it combines the features of a AVR and the features of the Vinculum I into a single chip.  A interface is still needed to convert the NDS GBA DMA interface into something that can talk with a uC like the Vinculum I, Vinculum II, AVR, etc.  I handled this with a CPLD but there is probably other ways of doing it too.

I will be posting a blog post today with the logic files and an explanation of how it works.

I spent a few minutes every day for the past two weeks writing up this blog post
http://blog.lukeskaff.com/?p=121

It covers the DMA interface between the DS and the FTDI vinculum.  Next blog post will cover the code for the PTP/MTP controller and schematic.

Cheers

Amazing work, Luke.

Thanks Steve!

It is long overdue for me to post this information so I have been working on a new blog post this weekend and the schematic.  Attached is the schematic, I will post the code and schematic in a new blog post in a day or two.

More than year have passed. Any news on further development? I mean, is there a possibility others can build a compact/portable device practical for location use?  Smiley

Thanks

It's sorta been mooted. There are android-based hdr controllers, etc. If anything, the fact that OCC is not USB-based is it's remaining strength, it works with almost anything. I'm currently hooking up two medium format Pentax's with a modified OCC design for FX work, and have recently used it to bracket with a Leica M8 and a Leica R4 (film!) camera.

Wishful thinking on my part, to avoid using ND filter to cope with daylight situations. Not an Android user  Sad

some  time has passed til luke posted a usb version.

Based on a found blog ( http://www.circuitsathome.com/camera-control/arduino-based-controller-for-canon-...) i spend some time setting up these version to the DS. Here allready the circuit plan. Maybe someone is able to reprogram the "bracket" getting that version supported by the DS.

The process developping the board is stil on going.
For testing the usb i use this board attached to th occ rev 3.3

edit at: 03:15:2012
-> new circuit plan attached. old one had a failure. The four data lines have to be attached to the maxim chip, not the atmega.

I know someone who can program the PTP code. If only he had one of your boards. Cheesy

Hello Steve,

that sounds good. Send me a pm with your address and iŽll send you the unit when i got them from my vendor Smiley and the final test has been done.
