Hi!
I'm trying to interface the Sonic Combat Module with an Atmel AVR. I have problems with the fire sequence. I know mr RC-CAM have done a similiar thing in his TOP RC-GUN AWS project using a PIC. Can anyone discribe how the waveform for firing these cannons look? I don't know anyone with a x-port equipped plane, and I don't have PIC-programming tools either.

I managed to trigger the the cannon with a 10-15% dutycycle FM signal with 100 Hz carrier, 1 Hz modulation frequency and 25 Hz deviation. Don't know why this works, I just played around with a frequency generator. I implemented this on an AVR and it seem to work quite well. I have tested it on three different sonic combat modules with success.
