Hi Chris,

You just need to be careful.
Some OSDs manually tap into the PAL signal via the sync line and some faster interrupts. The code running on these things is very time critical (as in, nops in the main loop) but they are cheaper to make as you don't need a MAX7456.

That said, good luck!

Just wanted to let you know that i am working on an osd for the paparazzi
autopilot that will tap on the messages for the modem and display the selected data on screen. While i was working on it i found a very cheap osd at Hobbyking with an AVR cpu and gps that has a price impossible to beat (~40 dollars with GPS) so i will use it and hopefully
write a different firmware.

The best is that it is open source and the code is freely available (CL-OSD) If someone has more free time than me i think this will be a nice project.
