# Arduino-TVout
|
||
|
|
||
|
# Hosted here to keep it available from Arduino IDE (and for simple download as the original Google Code has been archived).
|
||
|
|
||
|
This is a library for generating composite video on an ATmega microcontroller.
|
||
|
|
||
|
This branch of the TVout library has been patched to allow use with the Arduino Leonardo. The goal of this project is to create a simple interrupt 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,32U4,AT90USB1286 and more can be added by editing spec/hardware_setup.h.
|
||
|
|
||
|
There are some timing issues with the m1284p, may be related to sanguino core.

## Connections
|
||
|
|
||
|
SYNC is on OCR1A and AUDIO is on OCR2A (except on the Arduino Leonardo, where AUDIO is on OCR0A)
|
||
|
|
||
|
There are some timing issues with the m1284p, may be related to sanguino core.
|
||
|
|
||
|
On NG, Decimila, UNO and Nano the sync is pin 9, video on 7 and audio on 11. On Mega2560 sync is pin 11, video is on A7(D29) and audio is on pin 10.
