Ardupilot as OSD WITHOUT additional hardware (NO LM1881)

BaroneOSD is a PAL video overlay impression WITHOUT additional hardware required (NO LM1881 Sync generator).

Use only 3 pin:

D1 (USART TX) used to pump pixel in the video connected with a 330Ohm resistor to D6

D6 (AIN0) Video in/out, connect here you camera or radio TX.

D7 (AIN1) 0.3V Voltage reference (you can use a partitor resistor)

It is not a big deal, you can cut the tracks of two pin and with small wires solder them on required pins on the microcontroller or. You can modify modyfy the pcb of Openlog, it is freely available for download.
I have pasted the files here also;
OpenLog.brdOpenLog.sch

I'm near a new version, that use SPI port not USART, pin needed D11 MOSI, D6 D7 to use analog comparator (with only 2 resistor!!!).
D11 (PB3) is not used.
D6 (PD6) is "remove before flight"
D7 (PD7) is GPS power switch
How it is possible to use D6 D7?

P.S. I have found a small error in the Hardware Diagram

So...did anyone get this to work yet? Would be nice to get some more information on this...

awesome, but... can you explain (draw is better) how to connect camera and trasmitter to arduino? thank you =)

Can u post a wiring diagram of how you connect it inline to a camera and Tx

Neat stuff! What is the compiled code size and memory constraints?
