  1. Hi, I am using Zybo Z720 and Pmod ESP32 to explore on IoT control. I used several AT commands like "AT+CWMODE", "AT+CWJAP", "AT+CIPSTART", "AT+CIPSEND" and "GET <links>" to receive the last entry data from the Thingspeak. Here is the response I received from the Vitis Serial Terminal: Now, I want to make use of this data from +IPD response and control the GPIO and relay (relay connected to the GPIO pin). I know Arduino has sth like Serial.find() function and help me with extracting serial terminal's IPD response. I just wonder Xilinx Vitis has the same thing a
  2. I am looking at the petalnux demo here and These are a good resource. I am anxiously awaiting the update to 2020.1. However, I would can you include or provide here a list of the steps need to recreate the functionality in the distributed BSP. You don't need to provide in depth instructions as we can reference the provided petalinux project. For instance, I don't even know where to start looking for how to configure the HDMI video driver on a new project
  3. Can someone show me how to enable a GUI for the petalinux project available here: I changed it to have an external rootfs on the SD card and activated the matchbox desktop session in the rootfs configuration, but when it boots I get the following error: # matchbox-desktop ** (matchbox-desktop:1242): WARNING **: Cannot open display: Not sure how to get the HDMI display working...
  4. Hello, Can you say me why zybo didnot update the bsp version of zyboz7 board ? I see that they have only 2017 version . My petalinux version is 2018.3 and vivado is 2018.3 . So it giving me error failed to generate the rootfs while building project in the petalinux . It also says that No such file or directory. I search many forums and find that this is the problem with the bsp version. Does anyone know how use the 2017 zybo bsp with higher version of petalinux ? I used this commads petalinux-create -t project -s /home/kawser/PetaLInux/zybo.bsp petalinux-config --get-hw-description /
  5. I am trying to connect my PMOD MTDS to the Zybo Z7, without Arduino. I have integrated the IP files, connected it via block diagram, and set up a FAT32 microSD with the 2 files that are needed also. When trying to connect to Vivado I can seem to figure out how to get to the console for which I can do MTDS Firmware code so I can do a custom UI. Documentation does not help much with connecting this PMOD. Please advise if you're familiar thanks.
  6. Hello friends, I'm trying to implement ov9281 camera on my zybo z7-20, I'm using pcam 5C demo project, so far i have achieved damaged frames from camera(included pictures) can someone help me understand what's wrong with it, why its damaged? btw I'm using digilent's mipi IPs and on pictures you can see the highlighted spots are flashlights shining on camera.
  7. Disclaimer: I'm not an expert, just a student working on a school project. My zybo z7 board stopped showing up as /dev/ttyUSBx on my linux vm when connected using the UART microUSB port. On my windows host the com port does show up but I cannot open a connection with putty (115200 8n1), no error info or strange characters, just an error sound effect with no explanation. I tried everything on the pc side (driver reinstall, reboot, enable/disable port, different ports, different cables) but I suspect that it is the board not communicating. I use external power with WALL selected and bo
  8. I have time stamp on video in real time as shown in fig ,I have Zybo Z7 FPGA board can any one please help me how to text overlay and how the overlaying text can be changed dynamically please guide me .. Thanks in advance ....
  9. Hello all, I am trying to set up a CAN communication between a ZYBO Z7 Board with a PmodCAN Controller (connected on JE) and a Raspberry PI 3 using a Niren CAN Module as Controller. Letting 2 Raspberries communicating which each other via SocketCAN works fine, both can send and receive CAN data. Now if I try to let the Zybo communicate with the Raspberry using the example codes for transmit and receive data there seems to be no data on the bus. Neither the Zybo receives any data from the RPi nor the RPi from the Zybo. I have created a block design and tried the example codes according to
  10. Hello Digilent Community, I am working on a image processing project and was wondering if anyone had advice or could point me in the right direction. I have tried following some tutorials and example projects, but I am still trying to wrap my head around Xilinx Vivado and SDK. The project really shouldn't be very difficult, I think I am just missing some information or the best way to go about doing it. For the project I am using the Zybo z7-20 development board and want to save two images to an SD card. The two pictures are black and white frames from a video just seconds apart, so
  11. I am getting starting with Vivado_HLS 2018.2 and the zyboZ7-20 board. When attempting to create a project I find no default setting for the zyboZ7-20 board in the Vivado HLS "Part Selection". What is the recipe for giving the zyboZ7-20 board information to Vivado HLS? I see there are some examples using Vivado, but none using Vivado HLS. Being new at this, step-by-step would be very helpful. Thanks
  12. Hi everyone, So I have spent probably too much time trying to figure this stuff out on my own. I should preface this with I have little to no experience with these types of boards (FPGA). I followed the Demo documentation ( ) line by line, multiple times and keep netting the same results. I have installed version "Vivado Design Suite & Xilinx SDK 2016.4" and downloaded the appropriate project files for the PCAM 5D project (2016.4) I am using a windows 10 machine. The demo instructions
  13. Hi, I am new to the Zybo Z7 platform. I watched a video from Xilinx on using Xilinx SDK to run a simple "Hello World" program on the on-board processor. Following the steps shown in the video would however not work, as SDK doesn't recognize the Zybo Z7 board (Zybo-Z7-20). I followed the steps shown in the tutorial here and was able to get the "Hello World" displayed on the SDK terminal. Here are my questions: 1. Do we always have to "Export Hardware" and launch SDK from Vivado? In other words, can we directly launch SDK, create a new application project and somehow select the right h
  14. Hello guys, I am using Zybo Z7-10 and want to use a timer which polls e.g. every 100ms by starting a task in freertos. What is the best way to implement such timer? Do I need to use XScu_Timer or Global Timer or Watchdog Timer Thanks, Mirco
