I'm interested in trying to connect a Rembizi OSD to my APM. I've searched both forums and the code, but I can't find any hint that this has been implemented yet. I haven't read through the hundreds of posts in the rcgroups thread, though. I'd love to be proven wrong. :) Assuming I'm the first, I looked at this post by Blake Krone about integrating Rembizi into the ArduPilot code:
http://diydrones.com/profiles/blogs/integrating-remzibi-osd-amp
Let's pretend for a moment that I'm crazy enough to try something similar for the current APM code. I know I'd need to use the FastSerial code. Just like Blake, I'm using a UBlox GPS, so I assume I should examine the date code in the UBLOX class in case similar changes are needed. There are two parts where I'm utterly clueless, though: which pins I should use for connecting my APM to the Rembizi board, and (if not obvious from the first part) which serial port I should use in the code. In case it's relevant, I have an Xbee connected and I plan to add on the airspeed sensor and the magnetometer (once it's available). I think I'll have my own little Medusa when I'm done. :)
Any help or suggestions would be appreciated. I'll be happy to share my resulting code.

did you manage to find a way to connect a serial on the APM. Are you going to integrate this into SVN ?
Thx
Quick video showing progress so far, not sure why it is so slow and choppy at times. Probably my netbook that I'm using to record on. Unfortunately when I went to show turning on/off the OSD layer it just so happened that was when I finally got a GPS lock which automatically sets the home on Remzibi.
I just now was working on the whole Serial2 which you can't use obviously. I'm working out the sharing telemetry port stuff now.
For reference I'm using Ardu1.7 from Remzibi.
Chris, can you shoot me a message on how you guys were thinking of integrating it? No sense on doubling-up the work effort if how I'm going about it is acceptable.
The pins for port 2 are used for the I2C connection to the ADC on the shield. You cannot use them for serial communication.
If you want to use an xbee then you are "out" of serial ports, unless you want to work out how to share one.
