Hi Michael and everyone on the forum!!
I’ve successfully generated ntsc/pal video signal on an Arduino DUE, following the same concept of the TVOut library. So, I’m a few stepps from implementing the TVOut Library on the DUE!!!
What does it mean? an extraordinary 680*240 or 640*480 pixels resolution on an average TV screen!!!
… and of course, the next step after the library, it will be the integration of the Video Experimenter brilliant solution to the arduino DUE!!!
check this link to see the first examples achieved:
https://youtu.be/3PaF-g1nPGE —> 744*240 pixels with the rotating cube example!!
https://youtu.be/AEXSLQMT70A —> 680*240 pixels with 8×8 font, some drawing and the cube example… the fps is low due to fullscreen blanking after each frame… and it is a very high resolution so it takes some time to blank the screen array…
I hope I will be able to post the library (TVOut & TVOutVE!!) soon for those wanting to use a bit more power through a 32bit microprocessor!!
Cheers!
Great job — that’s really high resolution.
A Video Experimenter for the Due would be a completely different product though. The current Video Experimenter cannot work on the Due because it depends on particular features/pins of the ATmega328. It needs the input capture pin and analog comparator to be on particular pins, which they are not on the Due.You are absolutely right about the special features needed!!!, but for the overlaying capabilities, I think a lot of people would love to be able to draw and write stuff with a lot more resolution!!
DONE!!
and I’m pretty sure that with the Arduino DUE it should be possible to overlay color NTSC/PAL signal….
the video was taken with my iphone and the resolution of the overlayed image is 680×480 pixels…!!!😀 😀 😀 😀 😀 😀 😀
Hi everyone!!!
Did it!!!
it looks like I’m a bit obssesed with the TV signal and the overlaying capabilities of the Video experimenter concept….
Now on a LPC1768!!!
Hi,
I had a Chipkit Max32 for a while and never used it since the programming was a bit different from arduino… but, to continue with my obsession… I finally was able to implement the overlay capabilities with it…
Max32 first overlay experiment…
this was an 520×272 pixel test…. complete success!!
now…
second overlay experiment!!using an incredible 896×272 pixels!!!!!
the nicest thing i discovered about the pic32 processor is that one can access the full mcu speed!! i.e. 80MHz!!! different case is the arduino Due which can develop a signal only at mcu/2… i.e. 42MHz…
Other interesting feature I found is that the PIC32 doesn’t have one analog comparator…. it has two on board and fully available!!! so… this weekend I’ll be testing with TV capture !!!
cheers!!!
