DE0-Nano break-out board?

I suspect I missed this tidbit somewhere along the way. Has anyone done the work to get the DE0 break-out board to work with the P1V?

    Hmm there was a Parallax DE0 breakout board, but I can't find it in the store.

    This is the DE2 version of it

    No. I have the board. I'm wondering if anyone has re-mapped the pins for the P1V to work with it. In case no one has, I'm working on it right now

    I've attached updated pin mappings for the DE0-Nano which should allow the use of the "DE0-Nano USB" break-out board. The pin mapping is "vanilla" (pin numbers match the break-out board). So far, I've only confirmed that the RESN and PropPlug pins work. Once I get some LEDs to drive, I'll verify the other pins.

    I don't have the board anymore. I gave mine away before the P1v code became available. I wonder if Parallax has any plans to build more of them?

    Do you have the break-out board for the DE2-115? The changes I made were really easy to do in the Assignment Editor.

    Yes, I have the DE2 breakout board. Unfortunately, the DE2 is too big and bulky to take with me on the road.

    I think a lot of them changed hands when the later P2's started gaining interest Th2 P2 "Hot". At that time, Ken had said they were not going to make any more of the DE0 boards. With the release of the P1V code and the renewed interest in DE0's maybe they will rethink/revisit the adapter boards.

    It would be "quicker to market" for one of the board design capable members to put something together and put it out on OSH Park or Itead as an Open Source design. Maybe a group buy could be put together.

    I would think people would want different stuff on this board than the P2 boards because of the P1V/P2 differences.

    I built this Protoboard for my BE Micro CV

    This provides everything one of OBC's Propeller Experimenter Boards does: VGA, KBD, SD and EEPROM plus some breadboard space and sits nicely on top of the BE Micro. Both header rows are brought through as male pins to provide access to P0-P31 (and P32-P63 if you are so inclined)

    (Note: Half the breadboard space is currently used up with the resistors for the KBD - I need to change this and put them on the Protoboard)

    I have been playing with the DEO-Nano board design shown in the attached image. This design allows quick start accessory boards (eg, Human Interface Board) to be attached to the DEO. It includes a reset button, eeprom and prop plug port.

    Nice! I'll take two! :-)

    This looks very similar to my QuickStart Adapter. Mine has no EEPROM because it was made for the first P2 FPGA image nearly 2 years ago. Now it sees a second life...

    Seairth,

    Thank you for posting the pin assignments for the DE0-Nano. I haven't had a chance to play with it yet... my available attention span has been used with the other boards.

    At the time of your post you only had limited confirmation of the mappings... have you or anyone else had a chance to play with these assignments fully?

    Is there a pin mapping for the DE2-115 adapter?

    These pin mappings really do belong on Parallax's Official product descriptions. So, when there is some consensus, Ken should be flagged.

    Of the two add-on boards, I really like the one for the DE2-115, because it appears to leave the DIP connector of the DE2-115 completely open.
    I am hoping that this is the case... I want to put a camera on it:)

    On the other hand... the DE0-Nano board seems like it would have mass appeal since it offers easy expandability for important peripherals.

    I know that these add-on boards were designed practically over-night, without concern for anything other than the guys here... but they are really nice boards and with the right support from the guys
    on the forum might find a place in a broader market.

    If anyone is playing with the add-on boards... consider making a video and post it to YouTube.

    Thanks,


    Rich

    The QuickStart adapter board for the DeoNano, which I had described in this thread, is shown in place on the Deo in the first attachment. The second image shows a similar design for the BeMicroCV.

    Nice work NickL. Good to see these boards coming through.
