I sell the modchip on my website. you can find technicians at xrgeneralhospital :)

Hi, did you try to link it using my tutorial? Which version of SDSoC are you using? jonataubert.com/tuto/use_opencv_sdsoc.php

@@jonataubert yes I followed your tutorial. Version 2019.1

@@yuhengkit4427 I didn't try on any other version than 2015.4 and never used cv.imshow in that context. Do cv.write and cv.read work? I currently don't have any valid sdsoc license... I will try to get one. Please email me (see about section of the website) so that we can find how to make it working ;-)

plz reply me in your answer.

Hi, cool that you would like to play with that nice device :) 1) Yes, to do this, use it on the ZYBO with GNU Linux + OpenCV. Then, find a way to store each incoming frame in a specific (fixed) memory region (by using a pointer). This memory region will be shared with the "FPGA" part of the ZYNQ. 2) As you have the address of each incoming frame you can implement an SDSoC function (which is both a DMA + HW accelerator that process your data). This function will have to read data of the image that is located in the input video frame buffer and then, after processing, will output the processed image in an output frame buffer. This output frame buffer could be read by your software or even by another hardware peripheral, such as a DMA that could stream the data to a video pipeline (this is what is happening in the video here, the output frame buffer is continuously read by a DMA -> VGA pipeline). Just one important point: don't forget that when using GNU Linux the addresses in the user space are virtual. Good luck ;) PS: there are certainly some other ways to do this, please people, feel free to share your advice/experiences.

jonataubert Thank you so much for your advices It seems to be a hard task to do, I'm actually reading " The zynq Book " in order to get a good idea about FPGA zynq, after that I will boot the zybo with Linux, then I will check every step that you told me Thank you for your informations my friend :) Can I have your e mail to keep the contact with you ?

This is a really good book, I also started learning with this one and the application notes from Xilinx :) Just go to my website and you will find my email in "about" section. Cheers

Nvm, saw you held controller up to the screen. my b

Hi sorry for my late reply, the latency is ~10 horizontal lines of pixels when using the HW accelerator.

Hello, could you tell me more about your project? Please answer using info(at)jonataubert.com

15-20 minutes per sketch in A4 size and 30-40 minutes for A3 size (my Kyoto sketch video)

+Basil Mike Hello Irine Thank you very much for your comment!! It is great to have a nice message like this! I wish you a nice evolution in your sketches, the best way :exercices, exercices,exercices, then you'll do great artworks! I am preparing a new video from Kyoto, Japan. I'll notice you and the subscribers when it'll be out! Kind regards, Reynald www.reynaldaubert.com

Hello Tim I like to use directly the marker on paper without graphite pencil reference under it. That gives me more freedom. Sometimes, to create different effects I use dark graphite pencil mixed with the marker. You can see some examples on this page : www.reynaldaubert.com/wp-content/uploads/2011/07/PUCES-ET-CIRQUE.jpg www.reynaldaubert.com/wp-content/uploads/2011/07/ARMURE.jpg www.reynaldaubert.com/wp-content/uploads/2011/07/Hindemith.1.jpg www.reynaldaubert.com/wp-content/uploads/2011/07/vieille-ville.jpg www.reynaldaubert.com/wp-content/uploads/2013/11/CUBA-THEATRE-HAVANE-.jpg Best regards, Reynald Aubert www.reynaldaubert.com

Hello, I use the Faber-Castell Pitt Artist Pen Brush 272 (Warm Grey III). Best regards, Reynald Aubert

jonataubert Thank you, Lovely work btw. :)

Tomtac98 You're welcome ;)
