    What's really amazing is that something so simple was used to play videogame, and we liked it It's almost p*rnographic : twelve 7400 serie IC one 555 one LM340three MOS 65**

    Device locked licence ?

    Wonderfull ! thanks !
  5. Friendly greetings ! I see some (more or less cheap) board that come with a device locked vivado/ISE licence. It provide an "augmented" software suite (eg : chipscope pro) and (eventually) some ip core strictly related to the card. Node locked licence, and floating licence are super-expensive for the hobbyist. Do you know of there is a way to buy a device locked licence (eg : for the papilio pro) The xilinx website is really :angry: so perhaps it's available somewhere ... but couldn't find it. (eg: i can't even access the online store )

    papillio pro schematic

    Ho ok thank you

    papillio pro schematic

    Hello ! i'm reading the schematic of the papilio pro, here http://papilio.cc/index.php?n=Papilio.PapilioPro The spec say there is a 32MHz XO but the schematic show a 6Mhz XO. Is there some trick i don't know about ? or an error ? Thank you
  8. Hello everyone, i can find the schematic of this wing http://store.gadgetfactory.net/audio-wing/ (there is the schematic of the dual input on the website, but where is the single output ?) Thank you
  9. a+ is a channel a- is another channel, everything else is ground ? (Oooo guess who doesn't have a multimeter )

    The next generation Papilio - help me shape it.

    I checked some tutorials about this but i got some problem because of some difference between version of ISE. (where the hell is the library manager now ? )

    The next generation Papilio - help me shape it.

    The real problem here is "up-to-date" but i'll try to contribute when i can. thank you
  12. That's papilio & logic And papilio + gic. And the gic of papiliogic could be... mmmm. Graphical err... Imagination & Conception ? Graphical Integration & Conception ? Gross Inception Componant ? Guaranteed Instant Craziness ? Graphical Interface for Conception ? Going In Circle ? Generaly Impatient Constructor ? Well mmmm, dunno
  13. I'm my wet dreams, i'm designing my board using the very awesome and well know logisim software. So ... LogiFPGA, unfortunally it's a kickstarter project for the raspberry pi. Perhaps ... papiliogic ?

    The next generation Papilio - help me shape it.

    Friendly greetings ! I'm still a newbie, i'm very very interested in FPGA, mostly because i'm a sysadmin and i believe in FPGA embedded in a server for some specialised stuff the cpu suck at. But i'm doing it as a hobby because i don't know any company crazy enough to believe this, so i'm on my own budget Being a newbie, what could i say ? keep it cheap and simple : i never wanted to buy thoses overpriced dev board with tons of stuff i'll probably never need. Arduino like or arduino compatible shield : Yes thats nice. But ... I have some arduino shield, including an ethernet shield. can i use it with the papilio pro ? i have no idea, at all. showcase : i bought the papilio pro as soon as i saw the SID player video. you need as much "cool" showcase as you can ZPUino & AVR : i don't care. probably some people like this. high speed serial : yesssss pleaaaase ! i don't know if i'll ever need it but that's a good selling point. (the arduino certainly can't do that) RAM : i don't know if i'll ever need it, i'll probably need it yes. but that's another selling point hdmi ouput : well... meh. if you can provide well documented, easy-to-use, up-to-date ip core. Sure why not, but the VGA shield seem good enough for me. (i'm not going to plug my fpga board on a high end expensive screen that have only dvi & hdmi) hdmi input : i, don't, care. if i really want to process image/video, i'll do it using the usb port. or buy a specialised fpga card. (and good luck to get free ip core for video processing) sram over sdram ? i don't know, i never tried to use the ram ... but i will So, do i really need more stuff on the board ? Nope, not really. Whatever you do, please keep in mind that it shouldn't be too fragile or, at least, doesn't LOOK too fragile. The major selling point of the arduino is : cheap, easy to use, the shields, and ... gigatoooooooooons of library & endless count of documentation/tutorial. The major problem with fpga is : very closed system, very very expensive software & ip core. Arduino got a critical mass were people write bit of documentation here and there, others compile them in something readable, so you'll never be alone as long as you can STFW. Raspberry pi : mmm.... almost, not sure. All FPGA boards : lost deep in abyss. Whatever helping to connect to the modern world is good for me. VGA : it's ok, no need for hdmi USB : Yes, of course. best interface, it power the board, it program the board, it can be used to connect to program running on the pc Audio : Yep Ethernet : the arduino shield ? or embedded on the board with PoE to power it ? Other IO : i use my cheap oscillo/logic-analyzer for now What i need, i really need, is : up-to-date documentation, a collection of free ip core. (yes i know, it's the most annoying stuff to do). And... ho, while i'm here : where is the wiki ? Thx
  15. Process "Generate Programming File" completed successfully It works Now i probably need to do some quick fix for the Papilio Pro and ... that's all thank you again
  16. Friendly greetings ! So i decided to be serious about FPGA (finally!) I know there is this tutorial http://papilio.cc/index.php?n=Papilio.HighSpeedUART but it use the picoblaze I also found another one which seems to be a bit better (for my needs) : http://gadgetfactory.net/learn/2013/12/02/the-quickest-way-to-implement-pc-to-fpga-communication-using-a-papilio-fpga-board/ I want to use as a serial port (the ZPUino do it and i want to know how to do it in vhdl). I simply can't find a good starting point. The FPGA seems to be connected to this : http://www.ftdichip.com/Support/Documents/DataSheets/ICs/DS_FT2232D.pdf Simply... how can i use it ? Is there some ip core available ? source code ? Thank you
  17. Ok i'll try. i can't find the url i found earlier (but was also related to the picoblaze), i'll try the first one i pasted. If you tell me that it works, well, then it works thank you

    Ôôôôôôôoooo thank you very much. I'm going to do it anyway, i'm willing to implement it in logisim too. Did you find any datasheet about the 6507 ? Or is it really just a 6502 with less pin ? (look like that's what you did)
  19. Friendly greetings \o/ I'm ker2x, keru, kerunix, 35yo, Toulouse, France. (My french is somewhat better than my english.) I started to mess with computer 30 years ago and now i'm an experienced system adminsitrator (well, mostly linux administrator now). I'm interested in fpga since a loooooooong time, reading stuff about it here and there but : vendor evaluation boards are expeeensiiiiiive (omg!)i can't do any soldering (really, i can't, seriously)sometime you find not-so-expensive board but the shipping cost is the not-so-hidden cost.some vendors have cool stuff but : no price (they say "low-cost") and when you manage to get a contact you understand that they don't want to sell to individuals (because individuals don't buy consulting services, probably) Well, since a i started 30y ago, i obviously met the demoscene and i'm addicted to chiptunes Earlier this week i saw this : http://www.youtube.com/watch?v=YqSvkNjWnnQ (abusing the lissajous mode of an oscilloscope) And, yesterday, i saw this : http://www.youtube.com/watch?v=Ob8jZyfnujM (Oooooooo ==)1h later the papilio was ordered, with an audio wing (shipping to france will take some time). I'd like to share with you a collection of ressource that help me to understand fpga, code, computer, electronics, algorithms, ... everything you need to create your own operating system : http://wiki.osdev.org/Expanded_Main_Pageinterrupts : http://wiki.osdev.org/Interrupts & http://wiki.osdev.org/PIC (specific to PC architecture, but usefull)VGA (still PC specific, still usefull) : http://wiki.osdev.org/VGA_Resources(MIT free book) Structure and interpretation of computer programs : http://mitpress.mit.edu/sicp/full-text/book/book-Z-H-4.html#%_toc_start15 sorting algorithms in 6 minutes (because it's fun) : http://www.youtube.com/watch?v=kPRA0W1kECgBit hacks (MIT course) : http://www.youtube.com/watch?v=xc9DDSbf0NQ <- wow !a MUST-HAVE book if you had to buy only one (seriously!) : http://www.nand2tetris.org/book.php (also available in kindle format)Free Range FPGA (of course) : http://www.freerangefactory.org/site/pmwiki.php/Main/BooksIntro to spartan FPGA book (obviously) : http://forum.gadgetfactory.net/index.php?/page/articles.html/_/papilio/logicstart-megawing/intro-to-spartan-fpga-ebook-r34Inside the machine (because it cover different CPU architecture) : http://www.amazon.com/Inside-Machine-Introduction-Microprocessors-Architecture/dp/1593271042Open IP Core (can be usefull, lot of free VHDL) : http://opencores.org/SID \o/ : https://github.com/alvieboy/ZPUino-HDL/tree/master/zpu/hdl/zpuino/contrib/NetSIDhackaday (please don't tell me you never heard about it) : http://hackaday.com/reddit FPGA : http://www.reddit.com/r/fpga/fpga4fun : http://www.fpga4fun.com/ I'm probably missing tons of ressources, but they are the one i remember enjoying. There is one more link i'd like to add : http://www.fractalforums.com/ this is where we invent new fractals. Lots of crazy dude (and dudette), including myself, hopelessly addicted to complex numbers. One of my long term project with FPGA is to create a complex-number co-processor or, even better, a full software CPU optimized for fractal generation. (well ? perhaps i can hack the ZPUino ? Mmmm). *hugs*

    Hello FPGA world :)

    i got it \o/ It wasn't too slow

    Hello FPGA world :)

    i stopped collecing old computers My most power hungry computer is a "ControlData Cyber 910" wich is basically a rebadged IRIS 3000 with a 68k cpu (so it's pre-IRIX) and like 24 MIPS (i don't remember exactly) for the graphic card. Nice stuff, big like a small fridge, PSU rated at 60A 12V

    Doh, i forgot EEVblog youtube channel : http://www.youtube.com/user/EEVblog/videos And if you use an oscilloscope, this one is the first video you need to see : http://www.youtube.com/watch?v=BFLZm4LbzQU
