Hey... finally finished...
...lesson learned... I'll never do animations again. It simply takes too much time. But here they are. Enjoy the video! The next ones will be released way faster.
The project page and details for this video will be up soon

Composite Video on ESP32

Comments

Hi Bitluni, thanks you for the excellent projects! I have tried the Composite video on my -ordinary TV- and it works perfectly but when I try it on a car monitor device like this one: <a href="https://www.amazon.co.uk/gp/product/B0056WJP1M" rel="nofollow noopener" target="_blank">https://www.amazon.co.uk/gp/product/B0056WJP1M</a> it shows the image but flashes on and off about twice a second, would you have any idea why this would be? I have also tried a FPV screen and had similar results. thanks for any help or advice.

Hmm. I see some dimming in same frequency on other tvs but not picture loss. The signal is more stable when drawing a white frame around the picture. But I guess you could try to change some timings. Did you try to switch between ntsc or pal?

AnthonyRussell

Hi, thank you for the reply. I have tried both ntsc and pal, also different screen resolutions. I will experiment more, try the white frame idea and play with the timings as you suggest. Thanks for the help!

Hi, I have tried playing with the settings in NTSCProperties and PALProperties, lots of things changed but the flashing did not stop. I have made some video of the issue: <a href="https://www.youtube.com/watch?v=IhMgygpxT2k" rel="nofollow noopener" target="_blank">https://www.youtube.com/watch?v=IhMgygpxT2k</a> As you can see, playing TetrisSpaceX is difficult but not impossible :) If I sent you a screen from Amazon, would you be interested in investigating / debugging the issue? You can keep the screen. Best regards, Anthony

hmm... I will try to simplify the general code to output just noninterlaced pal with color as some viewers suggested. that might improve some stuff but it will take me another two weeks. If you get your project running let me know.. it sounds very interesting and thank your for your support!
