Hi there,

I don't know if this is the right board for posting this, but...
I just wanted to show you a project I have developed of composite video with an atmega328 microcontroller.
The reason I am posting it on the forums is that some of the users from these forums helped me accomplish this project :p So I wanted your opinion!!

It's not the good, but have in mind this is my first project of this magnitude.

Thanks!!!

Well I for one take my hat off to you! When you first posted I have to say I thought you'd never achieve this but it's a great solution and that has got to be the tidiest breadboard layout I've ever seen. Accelerometers too - whatever next?
Did you manage it in C alone or was there any Asm in the final solution?

Well done.

Well thank you :)
I have developed the controller last year, with an accelerometer also. So I just had to adapt it to my project :p

Hmm, I used an interrupt to trigger every 60us, that will wake the MCU from a short nap, and then comes the Hsync... That idea was reached only with C... But I had to use assembly loops for other delays (for example NOPs code).

Thanks for your comment!
