Hi,
i have read that the new graupner hot rc system has ppm output.
I think it would be a good idea to expand the software of the ppm ATmega to work with spectrum satellite receivers (uart) to make the LPC2148 autopilots working with 2,4Ghz rc systems.
Cheers, Heinrich

Felix,

I dont think Jeti have Satellite receivers which would mean hacking one to get a serial stream out.

Hi,

yeah, I know about the JETI receivers with PPM output. But it would be
nicer to know the JETI protokoll so you could use any satellite and do
the binding, etc. Just like for the spektrum.

Does anyone know if someone already successfully reverse engineered
the JETI protokoll?

Cheers, Felix

Hi Felix,

I've ordered a JETI TU2 for my radio and a modified receiver at the
Mikrokopter-Shop. That should work as PPM-receiver out of the box. In the
next stage it would be interesting to use the Jeti-telemetry to show data
like voltage, wich block in the flightplan and so on in the JETI-Box. That
is implemented for the mikrokopter, so it should be possible to create a
module for the telemetry.

Cheers

Christoph,

do you know the format of the Jeti messages? I would guess it is
different to Spektrum..
It would be cool to have parser for Jeti as well, I was thinking about
upgrading my rc with Jeti 2.4GHz.

Cheers, Felix

So the first question is solved, PPM should work. What remains is the
question of the license. Will the shematics (perhaps the eagle-files) be
available, like at the old APs, or are the Lisa-APs the beginning of
closedsource-only APs in paparazzi? Please don't get me wrong, but this is
really important to me for making some strategic descisions and might be for
some more guys too.
            
Sorry I have no idea what the licence is, I just sent my first two
children in exchange for one.

Eric
