  1. Hello, I need help on a Basys2 board, that show incompresible characters when Adept runs at begin. Then I get this when it Initialize Chain (see below). You can see the error on attached file. The board is from an school laboratory and it is use by many students, so nobody know what happend to get this status in the board. ===== Digilent Adept ===== Adept System Rev 2.7 Adept Runtime Rev 2.19 Adept Application Rev 2.4.2 Copyright © 2010 Loading board information...

  2. Hello all, Im new to this forum as well as new to the FPGA world. Currently i'm trying out a project that utilizes the Spartan 3e cp132 on the basys 2 to accelerate hash processing on my raspberry pi. I read somewhere that the basys 2's pmod host connector pins have 200 ohm resistors embedded to restrict current. Would it be fine for me to connect the digital spi pins of the RPI3 directly to the Pmod host pins of the basys or is the Pmod ACL2 required? In write up i read they directly connected to their fpga in similar projects but i wouldn't mind not destroying mine. Currently i have the
  3. Hello, I'm making a project using Vivado, a Basys3 Atrix-7 FPGA Board and the PmodAMP2. The purpose of this project is to make a digital piano, but i can't find the proper code to send a specfic frequency to the Pmod AMP2 using VHDL and Vivado. Can someone help me out ? I'm pretty new to programming in VHDL. Thanks ! Robin
  4. Hello everyone... I'm new to this world and I bought a Basys2 a couple of years ago to use in my graduation. But I have never used it again since that time! Now I'm interested in discovering this world a bit more and the JTAG interface! Is it possible to write programs and load them into the FPGA board without having the ISE software?

    BASYS2 - Adept testing

    I recently got my BASYS2 board. I installed the ISE Design Suite and Adept. I appear to have problems with the LEDs and the 4 buttons on the board. In Adept, when I run the test, I get the following issues. When I flip any of the last 4 switches (SW4 - SW7) on the board, on the screen the switch is shown correctly but the button below the flipped switch also darkens. Pressing any of the four buttons on the board has no effect on the screen buttons display. Is there something wrong with my board or is there something I need to do to fix this?
  6. Hi! My professor loaned to me their Digilent BASYS2 FPGA board. We wish to develop an FPGA-based Laser Remote Sensor (LIDAR) system. The BASYS2 will be triggered by the pulse driver of our Laser Diode. The Laser Diode pulses will be detected by a photomultiplier tube detector at selected rates and bin widths. We will connect the output (analog) of the photomultiplier tube to the BASYS2. How can we do this? Is it via the PMOD? Do we need an A/D converter like the PMOD AD1 or PMOD AD2? The BASYS2 has 4 PMODs with 6 pins each. Which PMOD (AD1 or AD2) is bette
  7. Jan. 4, 2016 Hi! I want to use the Labview 2014 FPGA module to make a VI that uses the BASYS2 Digilent Board. The BASYS2 has the Spartan 3E-100 CP132 Xilinx FPGA chip. I will interface sensors to the BASYS2 and use the VI to get data automatically and process it. I already installed Labview 2014, Labview 2014 FPGA Module, Labview 2014 Realtime Module. However, I cannot find the BASYS2 (as a target) in the FPGA module and also in NI MAX. I found that Spartan 3E is part of the Xilinx University Program (XUP) and there is a Labview driver for it but it uses Labview 2012. Also, the Spartan
  8. I am a newbie, just bought BASYS2 digilent FPGA Board. I have background on microcontrollers. C/C++ is no problem for me. But I am having some trouble with FPGA. Actually, not with FPGA but with Compiler and ISE. As you can see in the attachment, I configured the FPGA chip. I am using BASYS2 board. This is the implementation code: --------------------- module myModule(A, B); input wire A; output wire B; assign B = !A; endmodule ---------------------- And this is the ucf code: ----------------------- # Onboard LEDs NET "B" LOC = "M11"; NET "A" LOC = "C11"; ------------

    Basys2 PS/2 Keyboard

    Hello. Im working on a project that requires a ps2 keyboard to communicate to the Basys2 board. Does any one have any good links that might help me get started with this. Or, maybe would someone be able to post their Verilog code , if they've done it ? It would be much appreciated Thanks Liam
  10. Hi, I would like to buy Basys 2 together with NI multisim to save money. the site states that price for multisim is just 9.95 usd in case buy with basys2. Anybody know the way? Thank you. link:,66,1200&Prod=MULTISIM
  11. Hello. I found similar question “Working with DA4 PMOD on Nexys 4” posted on 23 Oct. 2014 and answer from JColvin. I understand the hint about usage of internal voltage. Nevertheless I don’t see output voltages. It is not easy to me to follow applied code, because I have learned so far Verilog and example is given in VHDL. I am electrical engineer and programmer by education, but I am new to digital electronics and FPGAs. I have acquired some initial experience by learning book “Digital Design Using Digilent FPGA Boards. Verilog/ Active –HDL Edition” by Richard E.Haskell and Darrin M.Hann
  12. Hello everyone, I have met an issue when I use a generic counter and associate it when other component : my counter doesn't count. Firstly, I have designed three distinct function : a 2 bit counter, a multiplexer and one function allow to use 7 segment displays of Basys2. Then, I have associated these function in order to obtain one block diagram. The output of the counter are used to activate anode of 7 segment displays and they also used as input of 4 to 1 multiplexer. Finally the 4 to 1 multiplexer ptovide input for a block wich allow to light one of four 7 segement displays. When, I test
  13. Hi everyone ! I need some help please : when I try to implement a counter in active HDL I have this warning message : " Route:455 - CLK Net:U1/q<23> may have excessive skew because 2 CLK pins and 1 NON_CLK pins failed to route using a CLK template " I explain : Firstly I have designed a basic counter with Basys2 board : library IEEE; use IEEE.STD_LOGIC_1164.all; use IEEE.STD_LOGIC_unsigned.all; entity counter_2 is generic (N : integer := 4); port( clr : in STD_LOGIC; clk : in STD_LOGIC; q : out STD_LOGIC_VECTOR(N-1 downto 0) ); end counter_2; --}} End of au
  14. i have a pmod da2, i use it with basys2 board I use the refcomp design given by digilent, fixing the digitals values I simulate, and implement it on board, verified signal with digital analyser... put a scope on analog outputs... everything seams to be good, but no anlog value on the output! Some one could help me? thank you

    Hi, I have PmodALS with basys 2. I need some example, in VHDL, to read data with the SPI protocol. I want to show the lectures on the 3 seven segments display of basys 2. thank you
  16. Does anyone use MultiSIM to program BASYS2? I teach an intro digital course that uses MultiSIM PLD Design to schematically program BASYS2 fpgas. I get a message when using ADEPT to upload that states: "Startup clock for this file is 'CCLK' instead of 'JTAG CLK.' Problems will likely occur. Associate config file with device anyway?" I can change this in Xilinx, but can't seem to in MultiSIM PLD. Any thoughts?
  17. Hello, I have successfully programmed my Basys2 using the 'djtgcfg' utility under Linux dozens of times, but I'm no longer able to do so. When I attempted to program the board yesterday, I got some unusual results: > djtgcfg enum Device: 3.....O......<. Product Name: Digilent Basys2-100 User Name: 3.....O......<.

  19. Hey every one! I use Basys2 board spartan3E 100k with Active HDL of ALDEC to study digital design. I have meet a problem when I try to implement my VHDL code the Implementation is ended and I have this message : "Warning: Implementation ended with warning(s)." In the Implementation report I have something like that : "ConstraintSystem - A target design object for the Locate constraint '<NET "an<3>" LOC = "k14";> [sw2led.ucf(37)]' could not be found and so the Locate constraint will be removed." I have tried to figure out but I don't know where the warning come from :
  20. Can we use Basys2 Pmods (GPIOs) for serial communication with outside world...? I want to implement a UART code on Basys2 board and want to use one of the Pmods (GPIOs) as Tx and Rx pins to establish a serial communication with outside world.. Can I do that..?
  21. 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
  22. Hi Can I use ISE webpack with the basys 3? I already have basys2 that I use with ISE webpack and was planning to buy basys3 now that I need more, but I wanted to know if I can continue to use the same software. I think you can't use vivaldo with basys2 but i can't find info if basys 3 can be used with the ISE webpack! Thanks!
  23. Hello, how can I implement this module using Verilog? And also, what is the meaning physical meaning of the 12 output bits of that module? Thanks in advance.
  24. Hello again I was looking at doing a servo project and bought a GWS-S03N servo motor and the HB3 PMOD. Looking at various sites, I have not seen anyone using the HB3 to control a servo. Is the only purpose of the HB3 to allow higher voltages to the servo motor than the Basys2 can output? It appears that pulse control is still coming directly from the FPGA board. So, if I used a higher voltage to the PMOD and motor, is there any chance of damaging the FPGA by connecting it directly to the control line of the servo? Is the HB3 more (or only) intended for driving standard DC motors and
  25. Hi, I need help to initialise and implement an inout port in BASYS 2(Spartan 3E) FPGA board. I tried using IOBUF and assigned that port to B6 or A9 or C6.I couldn't get the result. Without using the IOBUF, i am getting the desired signal pattern as output but in milli volt range. And i'm not sure whether i able to recive or not with out using the IOBUF since I could not test it.. I want to implement the I2C protocol, so the sda line should be INOUT, which I cant figure out...Should I use any specific PIn in Pmods of Basys 2 as Inout port.... Please help me with this... Thanks in A
