  1. @sbobrowiczPlease help me
  2. Hello, I create project on SDSoc 2015.4 using platform (https://github.com/Digilent/SDSoC-platforms/tree/master/2015.4/zybo_hdmi_in) and I select Operating System is Linux because I use about image processing. but I want to access 4 LEDs on PL. Can I access the LED on PL? How to access GPIO (e.g. LEDs) on OS: Linux Previously I used OS: Standalone project. I can access by Xil_Out32(XPAR_AXI_GPIO_LED_BASEADDR, 0x2); but on Linux I can't. Thanks in advance
  3. Hi @jpeyron, I suspect that number is 76 150 29 and 128 came from. Thank you.
  4. Hi @sbobrowicz, I'm learning about image processing on the Zybo board. from link I wonder about the source of the calculations grayscale images. Can you explain or refer to the relevant documents for me? gray = (r * 76 + g * 150 + b * 29 + 128) >> 8; Thank you.
  5. Hi @bogdan.deac, I have read the code from sobel_filter.cpp . I wonder about the code ... #pragma AP PIPELINE II = 1 What is it about? Is it about the document? I never met in writing a instruction on the software. I try to search in Google and not find. Thank you.
  6. Hi @bogdan.deac, Thank you for the advice. But I have more questions. If I use xfOpenCV on the Zybo board, Can I render the video in real-time via the screen? Using HDMI as input to the Zybo board. And the board sends out information via the VGA port to monitor. Thank you.

  8. Hi @bogdan.deac, I have a zybo board, can I do the above? Please guide me.
  9. I'm making a project about image processing. The board used in the project is the Zybo board and operates on a frame 1920x1080 (Full HD). My project is Square Area Detection Then motion detection within the rectangular area. I would like to ask for advice or guidance directs the operation of the mine. (I'm new to Zybo boards and I just learned recently.) If anyone has suggestions and links for learning. Please direct me and attach the link. Thanks in advance. ^__^
  10. I am attempting to make the u-boot.elf file for the Zybo following this guide. I have a problem in Step 21: Compile U-Boot I am running into an error though that I am not sure how to resolve. Has anyone seen this before? I just learn about Zybo board. Thanks in advance.
