  1. Hey guys,

    I'm very sorry for the hassle, I'm not shutting GF down or moving websites. I started a new job and went through a very intensive two week training period with 14 hour days so there was no time left to look at forum posts here. The hosting for the downloads just happened to expire during that period and I didn't see the emails. I saw it once the training was over and everything should be sorted out now. Things should calm down going forward and I should settle into a routine where I can keep up with forum posts going forward. Once again, sorry for the hassle.

    Thanks,

    Jack.


  2. Hello Sandro,

    The only thing that is different between the 2MB and 512KB boards should be that in the 2MB board there is one extra address line that the 2MB chip provides. The circuit board is exactly the same, its just that on the 512KB board that address line connects to a pin that does nothing while on the 2MB board it gives access to more address space.

  3. Sparkfun must have made a mistake then... I didn't realize they were even still selling Papilio boards. 

    I have a VGA wing here in front of me and R1, R2, R3 are 391 (390 ohm)  and R4, R5, R6 are 821 (820 ohm). So if all six resistors on the board you have are the same value then they made a mistake when they manufactured the boards...

    We should get you a better board, are you in the United States?

  4. The clocking wizard usually does a pretty good job of getting you close to where you need to be. Please look at this tutorial to see how to use the clocking wizard:

    32Mhz was selected because I wanted something below 50Mhz that would be considered low frequency. Also, for the Spartan 3E it had to be over 10Mhz if I remember correctly. I found two reels of 32Mhz oscillators for $10 on eBay and since at the time I was manufacturing all of the Papilio boards on a pick and place in my basement the decision to go with 32Mhz was made easy. :)

  5. If you try to connect the 96Mhz clock to an external pin you are not going to see anything on a LED attached to that pin, it is going to be too fast. You want to slow down the clock to something you can see.

    Please take a look under the symbols area for the Building_Blocks there are pre-made tools to help connect to a 32Mhz clock (which is the default clock for Papilio) and slow the clock down. You can do something like this:

  6. JTAG only works on Channel A of the FT2232 that is used on the Papilio Pro because MPSSE is only available on Channel A. The newer FT2232H has MPSSE on both channels so it should work to switch them around. Just double check the datasheet and make sure MPSSE is supported.

  7. Carter Lee,

    Here is the latest design that we have for an HDMI wing. We have confirmed that it works, and I actually manufactured 100 of these, and Alvie has this working with the ZPUino soft processor. But sadly, we never found the time to properly release this wing so it is just sitting around. I mentioned in another post that if you send us your shipping information at support@gadgetfactory.net I will send you one of these wings to play with for free.

  8. Hello Henrik,

    Have you had any luck with running downloading DesignLab and loading some of the examples to the Papilio board? That might be a good place to start to make sure that there are no unexpected hardware issues lurking beneath the surface. If you can run the Papilio DUO Quickstart and some of the other Demos such as VGA output then that might help get us on the right track. It is also where the latest version of the Retrocade Synth software can be found.

  9. Hello,

    There is no official guide to doing something like this but I can help you through the process. But there are several different ways this can be done and we will need to narrow in to a specific method before determining the correct pin numbers for what you want to do. So can you provide more information about how you want to do this? Are you using a Papilio DUO or a Papilio Pro. Do you want to use the AVR chip of the DUO or do you want to use the ZPUino soft processor?

    Thanks,
    Jack.


  10. Hello Carter Lee, 

    I don't think that Hamster has any of these HDMI Wings available yet. But I have a newer version available that I can send to you, as long as you don't mind any documentation or support... If that is ok then send us an email with your shipping information at support@gadgetfactory.net

    Thanks,

    Jack.

     


  11. Under windows Designlab is using the start command to open the .xise file. This means all your should have to do is make sure that *.xise files are associated with Xilinx. It should do that automatically as part of the install process. But if it does not then you can just right click on any .xise file and associate the file type with Xilinx ISE.
