Greetings,
I have developed a simple, yet powerful interface that lets the user display all extended ASCII characters, 32 user defined graphics, and all sort of drawings in a standard NTSC TV set, either CRT or LCD/plasma based. It only requires 1 available pin of the microcontroller to work (a standard serial protocol is used), and 4 different communication speeds can be selected. A variety of software commands provides added versatility, and it is compatible with most common platforms today, such as PIC microcontrollers, Arduino, etc.
For a detailed overview of all features please go to http://magusporta.com/shop/tvgen/tvgen.html or you may see a demonstration at https://www.youtube.com/watch?v=fQY5r0DlTaA
I hope you like it, and that you start showing the results of your microcontroller’s activities in a TV, like the 80’s!!!
