Handbook of hardware pinouts, cables schemes and connectors layouts @ pinouts.ru
We are collecting information about hardware interfaces of modern and obsolete hardware, pinouts of ports, expansion slots, and other connectors of computers and other devices . This information is essential for everyone who wants to investigate modern computer hardware, explore the how it works, connect various devices to computer. The hardware investigated here includes modern (PC, Apple Macintosh,...) and obsolete (Atari, Commodore, MSX,...) computers, mobile phones and some other devices (like GPS units, PDA,...).Forum - Arduino Pong
disabling the timer is quite important, each scan line in the signal must take 63( +/- 0.5)us, if the interrupt fires during the line generation, it will blow out the timing significantly, I will try to take a picture of what I get when the timer is NOT disabled, then you can compare what you're getting.
