  1. I have never tried out the ethernet shield with the Papilio DUO so not sure what the problem is that you are running into... If you load a blank circuit to the FPGA side then there should not be any conflicts... You could also try to use one of these types of ethernet modules: http://store.gadgetfactory.net/ethernet-module/ Jack.
  2. Yes, I haven't visited that code in a while but I'm pretty sure what you are running into is that certain libraries are disabled for the Papilio One because there is not enough memory to support them. What are you trying to compile anyway, I can't really tell from your pasted information... It should say in the comments for the example what boards are supported. I think the Papilio One barely supported the Amiga mod player by itself, but definitely not with other players... That was the whole reason for the RetroCade light version. It was made for the Papilio One. Jack.
  3. Not everything will fit into the Hyperion version of ZPUino. Hyperion sacrifices some memory that was available for program space for video memory. The Papilio One does not have any external memory so it is very memory constrained compared to the Papilio Pro. Then Hyperion makes it even more so... I would recommend trying the regular version of ZPUino for the Papilio One and see if it works. If not then the Papilio One does not have enough memory for the example you are trying to synthesize.

  4. This looks really cool, I can't wait until I get some time to dig into this and check it out some more. Jack
  5. Hello, The USB channel on the Papilio is a max of 3Mb/s so it will probably not be fast enough for what you are wanting to do. Alvie has created a USB wing that is a PHY and a USB core for the FPGA but it is just USB 1.1 I think so probably not fast enough. If we can get a USB 2.0 USB PHY wing then that would open up a lot more possibilities for projects like this one... Jack.
  6. Thank you for the understanding and I'm sorry we don't have a better answer. The material in the old ebook is still valid with the Papilio DUO, so it is still a great read... Jack.
  7. Hello RoelandK, I'm sorry but the eBook was never updated. Mike Field was going to do the ebook but right after the kickstarter finished he got hired on at a new job where he suddenly found himself with much less time to work on Open Source projects... We spoke about the book several times since, and he really wants to do the book, but he just does not have the time anymore... I'm sorry that was never completed, if you would like a partial refund or a store credit please send us an email at support@gadgetfactory.net and we will try to make this right for you. I have actually considered updating the ebook myself, but I think it would be after I finish up the next Papilio board and a new software suite to go with it since that will probably be the most beneficial to the Papilio community. After those are done then I think updating the ebook is the next step. Jack.
  8. Hello adamada, You should check all of your configuration settings. The easiest way to do that is to open the *.xise file and compare it to an xise file that is successfully generating a bit file that loads to spi flash. You have probably accidentally set the configuration to a quad spi chip or something... Jack.
  9. Hey Brad, The 5V rail is connected directly to the USB connector so you should be able to draw as much as the USB socket can provide. If you are powering from a USB socket then it is limited to 500mA unless you are connecting through a powered hub. The Voltage regulator on the 3.3V rail can supply a maximum of 600mA if I remember correctly. Jack.
  10. Hey Keith, that long 12" cable on the digital side is going to add resistance to the equation too. You might want to take a look at that next. Jack.
  11. Please take a look at the VGA section for the VGA circuit of the Computing Shield: http://papilio.cc/index.php?n=Papilio.ClassicComputingShield#vga This is probably the important part that is affecting your design: The VGA cable should be providing 75 ohm resistance. If you are not using a VGA cable with 75 ohm's then that might be why the colors look dim? Jack.
  12. DesignLab should also have some audio examples that will work with the LogicStart MegaWing audio output. They are ZPUino examples, not straight VHDL examples. Jack.
  13. The Papilio Loader should cause there to be a restart after the bit file is loaded... Maybe there is a bug in the Linux version, try to do a papilio-prog -C command and see if that forces the restart. For the multiple bit files, the spi flash supports that but there is no completed project yet to demonstrate that working... Jack.
  14. Hello, The digital joystick on the LogicStart MegaWing is super easy to use. It is just a digital logic '1' on each directional pin when you move the joystick in that direction. Here is the documentation with the ucf settings: http://papilio.cc/index.php?n=Papilio.LogicStartMegaWing#joystick Or download the LogicStart MegaWing ucf file: Jack.
  15. Hello Thomas, This looks very cool, I've been doing a contract job that is eating up most of my time. But hopefully I can give this a spin this weekend. Thank you for posting it, Dhia is going to get it up on the blog and social media tomorrow. Thanks! Jack.
