The goal of this project is to create a simple interupt driven library for generating composite video on a single AVR chip.
Currently the output is NTSC or PAL at a resolution of 128x96 by default. The library currently works on ATmega168,328,1280,2560,644p,1284p,AT90USB1286 and more can be added by editing one file.
News
Beta1 for version 1.0 is out!!! It has some it changes the hardware connections as well as some of the function calls see the wiki for full details.
Connections
SYNC is on OCR1A and AUDIO is on OC2A
| MCU | SYNC | VIDEO | AUDIO | Arduino | SYNC | VIDEO | AUDIO |
|---|---|---|---|---|---|---|---|
| m168,m328 | B 1 | D 7 | B 3 | NG,Decimila,UNO | 9 | 7 | 11 |
| m1280,m2560 | B 5 | A 7 | B 4 | Mega | 11 | A7(D29) | 10 |
| m644,m1284p* | D 5 | A 7 | D 7 | sanguino | 13 | A7(D24) | 8 |
| AT90USB1286 | B 5 | F 7 | B 4 | -- | -- | -- | -- |
*There are some timing issues with the m1284p, may be related to sanguino core.
Products Based on TVout
Wayne and Layn LLC now makes a shield that uses this library, the video game shield.
nootropic design is selling a stand alone arduino compatible board the hackvision.
Included Examples
Very simple as they may be.
