    Papilio DUO or Papilio Pro

    hi i just trying to compare between papilio pro and duo to see what is the difference and which one have more feature to do more project and implement more circuit with it from papilio pro page i see its contain 64Mbit Micron MT48LC4M16 SDRAM while Duo does not have SDRAM only 2MB ISSI IS61WV5128 SRAM can someone reccomend one of these boad to me i want the logic analyzer and implement it on the board is that possible with papilio pro or not my regards

    Papilio DUO or Papilio Pro

    i didn't use logic analyzer before also i dont have one its little expensive i want to learn FPGA so i think it's good chance to use the same board to implement Logic Analyze... i want to analyze USB signal between usb flash disk and PC or any thing have digital signal

    Papilio DUO or Papilio Pro

    thank you Mr.Jack Gassett i thin i'll choice Papilio Duo to start learing i'll buy the kits Papilio DUO-2MB and LogicStart Shield from seeedstudio.com but one more question please when i implement logic analyzer i thing i need probe to use it what is the best kit is this will be enough and connect well with Duo or not www.seeedstudio.com/depot/Open-logic-sniffer-probe-cable-p-619.html

    Papilio DUO or Papilio Pro

    thank you jack for reply one more question what if i want to implement or design hardware with Duo board need SDRAM like one in papilio pro in this situation can i use external sdram or the SRAM will be enough
  7. Hi everyone im Haider Ali from iraq 4th stage Computer Engineering Techniques maybe i have mistakes in my englsih ... sorry about it While I'm writing this I tired from how many time asking about it I was thinking it's easy to learn FPGA and then make your idea real by using it Asking about problem in FPGA and get right answer is million time harder than learning FPGA and VHDL professionally…….. I have graduate project next year in college so I decide to choice good idea and make it I want to work on fiber optic and FPGA by making device to convert the data signal from USB port or Ethernet Port to light by encode it and translate it via Optical Fiber to another Station to decode it and reconvert it to the Original Digital Discrete signal … I have some question about this and how should I work I make thread about my problem I Xilinx Forum buy I wish I didn't make it before I don't know why this company have Forum if they don't reply to the post After month someone reply by tell me go and read support file … I post the same thread in Altera Forum again and I get many replies from many members This link for my thread in Altera Forum please read it to understand what I want. http://www.alteraforum.com/forum/showthread.php?t=45282 My first problem in this project in how to decode USB protocol signal This is Daixiwen reply "You can find a few solutions to decode USB signals directly in an FPGA but they usually licensed, which means you will have to pay to use them. There is a free core available at Opencores but I don't know how usable it is. There is another problem though, for these cores to work you will need an external PHY chip. I don't know about any development kit that has one, so it means you would have to do your own daughterboard with the correct chip. Another solution is to use a development kit that already has a USB interface. Almost all the Altera kits have one, but it is used for JTAG access. You can reprogram the MAX II chip to use the USB interface for your own purposes, but then you don't have the USB blaster functionality anymore and can't configure the FPGA without an external USB-Blaster. Other kits such as the one you show here, or some Altera Cyclone V kits, have a second USB connector that you could use without loosing the JTAG functionality. But note that in all those cases, you won't emulate a generic USB device. Usually the integrated USB functionality on those kits is a serial link (UART) so you won't be able to directly emulate a USB flash drive." What I understand from Daixiwen said on post #6, I will need to decode USB protocol on USB Device side(FPGA1) and pass command to another Board(FPGA2) via optical, and FPGA2 will decode your optical command and issue USB protocol command in order to receive data from USB Flash Driver. And then send these data(from Flash Driver) back to FPGA1 and FPGA1 will provide data to PC via USB protocol But Daixiwen said there is no board have the ability to analyze USB protocol with speed 480 MBPS I get no more comment in this thread about it I send many messages in Facebook for many people and make many post in FPGA Group and FPGA Developer Group and I don’t get something better than my thread in Altera Forum Today visit sparkfun try to read all comment in Mojo v3 page and all Papilio model Pages After I read it I visit and go to learn sectionI read "High Speed Data Transfer Between Two Papilios" tutorial http://gadgetfactory.net/learn/2013/02/15/high-speed-data-transfer-between-two-papilios/ I find it great project I didn't know that papilios have the ability to translate data in high speed I feel one half is solved If I connect laser diode with high speed raise time and fail time response I could generate high speed discrete light beam via optical fiber But there is another half of my problem Is how to analyze USB PROTOCOL? I read this tutorial "VHDL SD Card Writer v1.0 For Papilio" In learn section too The person who make this tutorial use USB Card Reader as I thing so the USB analyze problem is solved too I wish if any member know anything tell me and post in this thread and can I make this project by using papilio board and analyze USB Port This is last time I asking about this idea if I get help from you I will work on it if not I'll leave it Thank you very much MY REGARDS
  8. hi every one i have question about Papilio Pro Does this board support matlab (system generaor) and does it have MicroBlaze Processor my regards

    Question about Papilio Pro

    im going to make my order from www.seeedstudio.com for beginner do you think this is enough mr offroad www.seeedstudio.com/depot/Logic-Sniffer-16bit-Input-Buffer-Wing-p-721.html www.seeedstudio.com/depot/Open-logic-sniffer-probe-cable-p-619.html (X2) www.seeedstudio.com/depot/Open-Workbench-Logic-Sniffer-p-612.html www.seeedstudio.com/depot/Papilio-Pro-p-1301.html i'll buy Digital Logic analyzer because its very important to me i want to understand how it work and want to learn everything about it

    Question about Papilio Pro

    thanks mr.jack but i think spartan 6 chip from xilinx supported by matlab or maybe not till now matlab did'nt support spartan 6 LX9 source : http://forums.xilinx.com/t5/DSP-Tools/Spartan-6-FPGA-LX9-Microboard-missing-hardware-co-simulation/td-p/409665 thats too bad i want to buy this board its nice and powerfull and cheap best choice for beginner
  13. thanks again mr alan i want to ask you about this man http://jorisvr.nl/usb/, he make USB data transfer in VHDLwhat is the purpose of his project im interesting to know
  14. Mr. alan thank you very much i want to ask about Papilio Pro Does this board support matlab (system generaor) and does it have MicroBlaze Processor because i have another idea about using FPGA in Graduate project and i want to use matlab i think Papilio is enough if its support matlab like Xilinx Atlys or Nexus 4 my regards
  15. but mr. jack it's to long waiting for December to get Duo try to make it complete early
  16. offroad good to see you post again you are right about using USB to URAT for Building but it will be slow now im thinking in idea more scientific than fiber optic idea ... i want to ask you about Papilio Duo in any time it will be relased
  17. last what i do is sending email to Benjamin David Lunt asking him to read this thread trying to help me this man have great website and tutorials about FPGA and Microcontroller also programming with USB Interface and use it in electronic projects i got his answer and i thing that's enough to me i will try to do it by myself from scratch thank you very much Ben for your answer and thanks for every one post trying to help me admin please close the thread the answer from BEN :- Hi, First let me say that I congratulate you on your desire to build this project. After reading the replies in the links you sent me, and not knowing what kind of background and experience you have with electronics, I might have to agree with some of the replies when they say "start smaller". A blinking LED is a pretty easy project once you get started and learn a bit. http://www.fysnet.net/docs/appendixq.pdf However, if I was going to create a communications device between two PC's, 100 meters apart, using fiber optic cable, I would start with a device at both ends, similar as you see in the .pdf file above. Each device would allow you to send and receive data to and from the device using a low- or full-speed USB port on the PC. Then I would use the ATTiny2313 to send bits (flashes of light) across the fiber optic wire. However, you will have to write software (firmware) for the 2313 to send start, stop, and parity bit information, just like the old time serial ports do. This would also be considerably slow, maybe 8 megabits per second, since the 2313 runs at about 16500000 Khz (or 16.5Mhz). (Normal USB communication is 12Mhz, for low speed devices such as the one listed above) However, this would accomplish the task you are trying to do, though considerably slow. You would also have to have an external power supply for the sending and receiving diodes, (each device having one of each). The USB's 5.0 volts, 500milliamps most likely will not power them. Here is my suggestion, and please take it as one guy who learned hands on just as explained above, to another with all due respect and admiration for your desire to learn. 1. Buy a cheap bread board, something similar to http://canada.newark.com/twin-industries/tw-e40-1020/breadboard-solderless-830-tie/dp/56T0250?MER=TSTSO_S_C_BreadBoard_None 2. Buy all the components described on page three of http://www.fysnet.net/docs/appendixq.pdf (minus the break out board (line 2)). 3. Assemble the three projects described in that appendix. Once you have a good knowledge of what they do and how they do it, I think you could go quite far creating a device to send and receive data across a fiber optic wire. You will need to realize, though, that it would be considerably slow, and maybe even unreliable, though if you are simply doing it for the task, then by all means, do it. Now, there are a few other questions you had, that I will try to answer. You want to be able to grab the data from D+ and D- and simply send a 1 or 0 bit along the optic depending on the values D+ and D- are. This will not work. The USB must have an ACKnowledge that you received the data, etc. You can not simply monitor D+ and D-. The USB will expect bytes in return after each packet is sent, using these two pins. Second, by sending the commands explained in the AppendixQ .pdf listed above, you will see that you can bring high one of the pins of the 2313, maybe hooking it to pin 7 of your "transmitter" as you explain in your post(s), keeping in mind the amount of current supplied by the 2313 will be less than 500milli-amps. Therefore, you may need an external power supply and a "relay" (a transistor?). I hope that I have been of some help to you. Ben
  18. thanks for advice what about papilio duo i like it very much (cheap and nice and have good spec tech) when it will be released
  19. hmmmmmmm............ what FPGA board you suggest to me to start there is Nexys 3 Nexys 4 Papilio Pro Papilio Duo(im waiting this Board) Altera DE1 Altera DE1-Soc every one i asked him about xilinx he toold me there is no enough materials and help file on the internet as like altera also xilinx forum not like Altera Forum is better thousands time and i try that by myself its really hard to choice i dont want Spartan 3e its old and don't support matlab
  20. offroad thnk you for posting you said the truth but your comment made ​​me desperate hamster thank you for posting i dont thing arduino have the ability to send data in speed up to 12Mb/s also this tutorial show how to connect device have usb port to arduino not to use usb data signal or analyze it because arduino have just Atmel Microcontroller 16 Mhz that's all
  21. thanks for reply i want to send data at same speed that USB 2.0 have 480 Mbps i want to use full-duplex protocol but sir what is the hard in USB protocol the use have D+ and D- these termials transfare discrete data signal i have have an idea if analyze use protocol is hard Why we don't consider as a signal source by another world there is many Digital logic analyzer in the internet based on FPGA like this Great one https://www.kickstarter.com/projects/dreamsourcelab/dslogic-multifunction-instruments-for-everyone so we could analyze the signal from D+ and D- then process it inside FPGA to run the Laser Diode to Generate the Pulse Light Beam i forget some thing DSlogic based on Spartan 6 and Papilio Pro FPGA also Based on Spartan 6 so i thing there is no problem to make the Papilio Analyze the Signal as Logic Analyzer...or you what to say some thing what about this sir
