Hi Chris,

I did a simple OSD based on the Parallax propeller chip for use with a different autopilot (Attopilot), it will be trivial to modify it to listen to the TWOG/Tiny serial output stream. I have the schematics and source code in my blog. Getting the OSD to work with Paparazzi is on my project list, but first I need to finish connecting my EagleTree airspeed and altitude sensors to the TWOG (through the I2C bus). You can find more details in my blog (scroll down to the OSD posts):

Hi Mike
No i mean airborne.
What i was thinking is that since my osd (also has pitot, air pressure sensors rpm sensors, fuel sensors etc. ) has a GPS input for displaying gps data, i can use a microcontroller that will listen to the airborne serial modem (much like the Uart tunnel firmware) and present the data to the osd simulating a gps.
You see any problem in this approach?
I am asking because if there is a problem in my way of thinking i don't want to waste any time on this as it is only an idea i have and i haven't actually started working on it
