  1. I am using the Electronics Explorer board, and I have a need to decode 3 different serial input lines, using a single CLK signal. Two of these serial input lines need to be decoded into 2 16-bit hex words (one 16-bit hex word for serial_in_1 and one 16-bit hex word for serial_in_2), triggered on both the rising and falling edges of CLK. The 3rd serial input line I need decoded into an 8-bit hex word, triggered on the falling edge of CLK. Is there any custom decoding functionality to perform something of this nature?
  2. I just got this up and running: http://youtu.be/dIAJrQxToCc It's a custom TFT LCD controller board using only two PMODs. The board controlling it is an FPGA devboard that communicates with the host computer using the FTDI's FT2232H in synchronous FIFO mode so that I can transfer data between the host and board at a rate of about 25MB/s using a simple protocol. I wrote a scripting tool that glues together wishbone cores to create an FPGA image using a simple configuration file. Editing configuration files are great but I thought it would be so much better if I could modify the FPGA image by using a GUI so I worked on an application that does that. Here is a screen shot of how I visually created the LCD controller. One of the big limitations of using USB 2.0 is the relatively large overhead to initiate a transaction, It's much faster if you send a large chunk of data. So instead of writing directly to the LCD controller I write to the SDRAM and then configure the LCD controller to read directly from the memory. This way I can write a new frame down to memory while the LCD controller is reading data out using a double buffer scheme (host writes to back, controller reads from front, then flip). The protocol to communicate with the FPGA is a really simple protocol abstracted away in Python to simply 'read' and 'write'. It was pretty cool to communicate with the FPGA using a python module but I thought it would be so much better if I could interface with an FPGA using a GUI. So I added a visual interface to communicate with it (That's what I was using in the video). If you're interested in the board here's the link: http://wiki.cospandesign.com/index.php?title=Dionysus the code to control the LCD is here: https://github.com/CospanDesign/nysa-verilog/tree/master/verilog/wishbone/slave/wb_nh_lcd The code is designed to be as generic as possible, so if you want to adapt it to your project it really just needs a wishbone bus but you can bypass Wishbone by just using the nh_lcd.v

    Basys �

    I need a program to count the turns of a motor, could tell me I need?????????
  4. Hello, Are the Basys 2 and the Basys 2 Spartan 3E FPGA boards the same?. Also, I saw you have a lot of labs of the Basys 2 board's requirement in both the Digilent website and the "Real Digital - A hands-on approach to digital design" text book. I would think if I buy the Basys 2 Spartan 3E FPGA board for my class at University of Calfornia at Irvine and use this FPGA board for the labs on your website and the text book "Real Digital - A hands-on approach to digital design". If I do this way, I can save cost for buying the FPGA board. Have the great holidays, Jonathan Tran
  5. Let's say I have a .bit file on my Mac, and I've got a Nexys 2 plugged into a USB port. As far as I know, Adept isn't available for OS X. What, if any, are my options for programming the board? Is there any documentation available for interfacing with the USB-FX2 controller it uses? (If it comes down to it, I'm comfortable putting something together with libusb.) (Yes, I'm perfectly aware that the Xilinx tools don't run on Mac OS X. And no, I'd prefer to not use a virtual machine. I have my reasons.)
  6. Hi, I've been working for a while now to create a program which generates a specific signal. I think I may have succeeded but I don't know how to verify that. I was hoping that there would be a way to use the Diligent Adept software or Xilinx ISE to see what my board is outputting. Hardware/software; Im using A nexys 4 board, ISE 14.7, and adept 2. The code I have was generated by Matlab's hdl coder and the out puts are two 10-bit signals. Thanks.

    Nexys4 Board.

    I was Interested to see the Nexys4 DDR board appearing the the "Coming soon" category (http://www.digilentinc.com/Products/Detail.cfm?Prod=NEXYS4DDR) Makes me sad to see the old boards going End Of Life, especially since the Nexys3 and Nexys4 are relatively new products.
  8. Here is a question a customer about programming JTAG 3 with older FPGA board. Can someone help on this? QuestionsI was wondering if I could use the JTAG 3 cable to program older digilent fpga boards that use the 6 pin connector?I understand that the connector is different, but if I hook up the right signals from the 14-pin connector to the right pins in the older 6-pin header, that should work as well right?
  9. I have a customer asking the following question. If I buy the $10 Basys 3-locked Vivado Design Suite, would the license enable me to install it on more than one computer? And if not, could I purchase an additional copy for another $10? Can I someone answer?
  10. Does anyone knows about Rugged Plastic case for Zybo? Is there mentioned that on our website? See the customer's question: We are planning to use the Zybo board in some new courses that that we have at the Technical University of Denmark. I'll be teaching two of those courses. Since the boards are going to be used in a lab environment we would like to protect them. I've can see from the description of the Zybo that you have on your web site that you offer also a Rugged Plastic case. As far as I know Digilent doesn't offer that. Is there any place where I can buy the case? If you have a 3D model of the case might also help since we could 3D print the cases ourselves.
  11. What is the target pricing and availability for the new NetFPGA SUME board? http://netfpga.org/2014/#/systems/1netfpga-sume/details/
  12. Hi all, I am a newbie into the world of FPGAs and HDLs. I am currently taking a logic design course where I am required to present a project by the end of this year. I would like to buy either a Basys3 or a Nexys4 board, but I am unsure as to how I could interface any of these boards with other external components, such as sound sensors, servos, (another development board perhaps?), and so on. Please, try not to consider Pmods, as they are somewhat expensive to my budget for now. Your help is greatly appreciated.
  13. Hi all, I try to store data in my Spartan-6 fpga, but I dont really know how to start with. Can anyone give me some suggestion? I've been trying search for any sample code to do that but so far I have not found any yet. Any help would be great appreciated. Thanks!
  14. Hello, Starting with VHDL coding and working on FPGA, I am interested in this field and need more the improvements for my self in day by days basic. I have my development board of Spartan6 - FPGA and need to buy the lab book of "Real Digital - A hand-ons Approach To Digital Design" for lab purposes, and get more hands-on or experiences. I have two questions and need to discussing with all of you: 1. If I use this lab book above, can I use the Spartan-6 to work all or some exercises in this lab book?. 2. Are all exercises in this lab book of "Real Digital - A hand-ons Approach To Digital Design" having their answer keys or the screen captured solutions from their simulations?. Thanks
