  1. Can someone show me how to enable a GUI for the petalinux project available here: https://github.com/Digilent/Petalinux-Zybo-Z7-10 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...
  2. Hi, I recently wrote a program that runs on the AD2 to close the loop on a system I am controlling. My problem now is that I will have a person unfamiliar with coding using this. I was wondering if there were options for creating a simple GUI to control inputs into my script. Like polling from a slidebar the frequency of a sine wave, I use in the script or test windows. I am particularly looking at the StaticIO but it seems to be limited to only the digital I/O pins. If it is not available thru Waveforms Beta will the SDK be able to do something like this? Are there any previous pos
  3. Hello! My task is creation of real-time system which can draw simple graphics figure on monitor (VGA) when the system register input pulse. The main difficulty is to draw this image only once (for measuring man's reaction time: time between image drawing and the button pressing). I think it'll possible to use FPGA to register input pulse and to generate VGA signal with required parameters. But I don't undestand can the ONLY ONE image frame be drawn at input pulse interrupting or not? The main task is to minimize time delays and in this case I can't use the standart solutions. For example
