  3. Hello, I'm using MTDS, that is working well in portraito mode. But when I change orientation to landscape mode, the TextOut() dosen't draw beyond 30 chars(240 pixel?). My initialization code as follows. Do I need some more setting for landscape mode? regards, mtds.begin(); hdsDisp = mtds.GetDs(); hbmp = mtds.GetDisplayBitmap(); mtds.SetDrawingSurface(hdsDisp, hbmp); mtds.SetFgColor(hdsDisp, clrWhite); mtds.SetBgColor(hdsDisp, clrBlack); mtds.SetTransColor(hdsDisp, clrBlack); mtds.SetPen(hdsDisp, penSolid); mtds.SetDrwRop(hdsDisp, drwCopyPen); mtds.SetBkMode(hdsDisp, bkOpaque); mtds.SetFont(hdsDisp, hfntConsole); mtds.SetIntensity(hdsDisp, 100); mtds.SetDisplayOrientation(dsoLandscape); mtds.TextOut(hdsDisp, 0, 0, 40, "1234567890abcdefghijABCDEFGHIJ!@#$%^&*()");
  4. @Ciprian hi .. i appreciate your help and with ur post i easily build the petalinux package.. now i have an issue... i put the BOOT.bin and image.ub in SD card... and i can see on my terminal zybo is booting... but there is no display on HDMI... nothing that is boot log # Loading kernel from FIT Image at 10000000 ...

  7. Hi @bharaths, Can you provide some more detail on what DDR you are attempting to read from/write to? Are you using the on-board DDR present on the Nexys Video? If you are, the DDR chip is hardwired to a 1.5V bank so you would not able to readily use 1.8V logic with it. If you are using an external DDR chip (presumably DDR2 if you are using 1.8V logic), you could use the FMC connector to facilitate the communication between the LVDS and HSTL logic. Based on this forum thread from Xilinx, you should be able to directly use HSTL and LVDS with AC coupled termination with both receiving the others signals without issues. Let me know if you have any questions. Thanks, JColvin
  8. can LVDS18 drive a diff_HSTL_II_18 in the artix video board? I want to capture 250Mbps DDR data using the FPGA, it is driven by a LVDS driver, can I use diff hstl II in the artix video board @jpeyron
  9. Hi @rosey12, I would recommend you look at online troubleshooting instructions for this as the error does not pertain to an FPGA board of any kind, but your computer; if you are uncertain of how to fix this I would recommend you take your computer to a local repair shop. If you have any questions about Digilent products, please feel free to post them. Thanks, JColvin

    Thanks, I can manage measuring it. Just hoped I could get around it.
  11. Hi, Homework solutions for the Real Analog materials do exist (though they are all scanned copies of the original solutions made by the creator of the Real Analog materials, so Digilent has not gone through to verify the complete accuracy of all the solutions). However, it is my understanding (I am verifying this) that only verified instructors/teachers will be able to get these solutions in the interest and spirit of helping maintain academic integrity for those are taking this as a course at a university. I do not know the policy of providing solutions to users who are going through the material on their own time without a formal setting, partially because of the reality that there is no real way to determine if this is actually true (or just a student pretending to do this on their own time) outside of the honor system, though again, this is just a guess on my part and not an answer. I have contacted our product manager responsible for the Real Analog material to get her thoughts on this, though they are out of the office this week at a conference, so it may be a few days before I hear back. Thank you, JColvin
  12. Hi @Sduru, I found a xilinx forum that that discusses this issue here. For their project the .project and .cproject files were referencing an obsolete hw_platform that no longer existed. They manually edited the files to the new hw_platform--now the design worked. Did you use the 2018.2 project from the release page here? Did you import the fsbl and pcam_vdma_hdmi from the sdk_appsrc folder in the Zybo-Z7-20-Pcam-5C-2018.2.1 folder? best regards, Jon
  13. Hi @vivekraj2992, We provide board files for our FPGA development boards that include QSPI flash IP configured for the Genesys 2 as shown in the attached screen shot below. Here is a tutorial that will assist with installing the Digilent Board files. best regards, Jon

    DDR3 input clock source

    There is only a single 100MHz oscillator that's loaded (IC3). The other one (IC2) is not loaded. In order to meet timing the DDR reference clock and DDR system clock have to be in the same column as the bank that contains the DDR3 interface. I don't recall what the thinking was when we included the 12 MHZ USB clock (UCLK) that goes into Bank 15, but you should be able to clock the entire device from pin R2.

  16. Hi @cliftw, Digilent simply sells the Multisim Student Edition (as opposed to licensing it), so we are not able to readily comment with certainty in terms of who is authorized to install and use that particular edition of Multisim, though it is my understanding that the $40 version is a permanent license, so long as the user remains in enrolled in the Academic Institution, as per section 4 of Addendum E in the English version of the National Instruments Software License Agreement, I am not a lawyer, but the language used in National Instruments Software License Agreement makes it seem like to use a Student Edition License the user would need to be in "continuing education classes"; there is apparently an option for a secondary school license (as mentioned in Section 5 of Addendum F of the same license agreement), though I don't know the details of that beyond what is stated there. In terms of the limitations of the software, I am not certain if there is limitation between this particular Multisim for students vs the one for education in general. I do know that the $40 version does not come with a Standard Service Plan (which according to NI's website offers live phone and email support from NI engineers, automatic version updates, access to training and demonstrations, and access to historical versions). I don't know what you are planning to use in your course, but depending on your needs/planned classroom material the free version of Multisim Live from National Instruments may suit your needs. In the end, you will likely need to contact National Instruments for accurate information on the available licensing details. Thank you, JColvin

  20. Hi @andre19, Welcome to the Digilent Forums. What ZYNQ development board do you have? I would suggest following the Getting Started with Zynq tutorial along with making sure that you have the Digilent board files installed. Digilent has board files that correctly configures the ZYNQ processor along with the DDR3. Here are the tutorials that we have available Getting Started with the Vivado IP Integrator, Getting Started with Vivado, Installing Vivado and Digilent Board Files and Getting Started with Digilent Pmod IPs. I will pass on your desire for more information on the Zynq core, AXI interconnect, GPIO, proc reset IP Cores to our content team although I believe that currently we do not have the bandwidth to create tutorials for how to edit properties of the Zynq core, AXI interconnect, GPIO and the process reset IP Cores. I would suggest looking through the Zynq-7000 SoC Technical Reference Manual, AXI Interconnect v2.1 LogiCORE IP Product Guide, Processor System Reset Module v5.0 LogiCORE IP Product Guide and AXI GPIO v2.0 LogiCORE IP Product Guide. Xilinx does have a lot of documentation/examples on how to use their IP Cores available from the block design by right clicking on the IP. I would also suggest looking here (if you used the default installation path): " C:\Xilinx\SDK\2018.3\data\embeddedsw\XilinxProcessorIPLib\drivers" for examples on how to uses their IP Cores in SDK. The ZYNQ book is also a good source of information as well. If you are still having issues with the Getting Started with Zynq tutorial please attach screen shots of your block design. best regards, Jon
  21. We have both of these and would like to use either of them to measure dc voltages. The problem is we are using robotics to move our sensors so we also need the x,y,z coordinates as well as the voltage read at those coordinates. Is there any way to ask the hardware to report what it is reading? Our software basically positions the sensor in one of 900 possible grid locations and we then measure 2 voltages and compute the current from the voltage drop across a know resistor as well as reading magnetic field strength. If we could put the coordinates into the log perhaps using the digital i/o. We just need a way to indicate the position where we took the readings in the log file somehow. Thanks.
  22. Hi @sambuls, LabVIEW 2014 Home Edition is indeed based on LabVIEW 2014; it includes the Full Development Version of LabVIEW (as opposed to a Student Version of LabVIEW) and is a lifelong (perpetual) license (more details available on the license agreements here and here). I'm not familiar with the Student License so I'm not certain if it's yearly or not; that would be a question for National Instruments rather than Digilent. Unfortunately, there are currently no plans to update LabVIEW 2014 Home Edition to a newer version of LabVIEW, nor do I anticipate there being any plans to do so. Let me know if you have any questions about this. Thank you, JColvin

    DDR3 input clock source

    Hi @mishu, I believe we added the additional oscillator to help meet timing and eliminated propagation delays with the DDR3. I have reached out to a more experienced engineer to see if they have any additional input as well. best regards, Jon
  25. Hi @PallaviCharupallli, Here is is the resource center for the Zybo Z7. The DMA Audio Demo on the resource center should help with understanding how to use the audio codec. The Digilent board files correctly configure the Zynq processor along with the DDR which is tied directly to the ARM processors. I have attached an image to help visualize the ZYNQ processor architecture. Here is the ZYNQ book that should be helpful with better understanding the DDR and Audio codec. best regards, Jon
