 If you never flash this radio you can find all documentations on er9x project found here :

modding your radio and flashing

http://code.google.com/p/er9x/

or you can find a Solderless Pogo board

 

for flashing I would recommanded to install eepe :

For the transmission you'll need a wireless RS232 high speed datalink, you can use xbee

but in europe I cannot use 900Mz and you mus modfify like for FRSKY project

My radio:

 

Due to the ATMEGA64 we approach the maximum memory, and in my version of gv9x-mavlink I remove the splashscreen,
the helicopter option (all mixing is done in ArduCopter)
and displays statistics

the binary is here :

Next time, I have to explain how to set the rotary switch.

Tell me if you have problems.

Sorry I never try xbee, but take a look at this post:

http://diydrones.ning.com/forum/topics/alternate-transmitter-telmet...

I used a KYL210 433Mhz RF module with a MAX232 converter that I found on ebay.

 

If you want to use my firmware,

I must release a new version because they are some problem with 'Arducopter v2.1.1 alpha' (systemid was 7 and now they can be change by parameter).

There is a telemetry downlink on the Frsky RX why not use that?

In my case I wanted a light Ground Station that could help me to change the setting of PID outside of my house, that's why I needed an uplink.
After I added some more display to see when APM and the GPS was ready, but this function could pass through the downlink of FRSKY, but it must change the APM software.

I also add the change of the flight control by PPM or via the MAVLINK.

I plan to add one function if I had enough memory in the TGY like memorize way point. Example : put your model at location 1 and with the transmitter send MAVLINK CMD to memorize this location and so for location 2.

Did you know the 9x uses an atmega64? You can remove it and put a atmega128 in it's place and double your mem. I've been looking for a RX hack to uplink to the FrSky if that works there should be some use for the 9x that way. With a bluetooth to your laptop ground station and your antenna tracker. Free up 900 mhz for your video goggles and get rid of all the nasty wiring!

Please forgive my lack of Knowledge here.....I have a T9x transmitter V2. I am going to use the APM2 board when it is available . 

Surely if I install the Frsky tx and rx with telemetry, I will Not need Xbee to send back data such as voltage or gps location ?

Sorry if this has been mentioned in a different context. I am still trying to take it all in ! ....electronics is second nature but as for software / code ect... I am lost.

There are some post by Earl about using the 9x directly to receive data from the FrSky but it is one-way you cant send data to the RX. If all you want is to receive telemetry it does work for that. It won't however replace the Xbee's if that's what you mean.

I'm only hoping for batt voltage/GPS location data (live) to be sent back to the radio  . But would it need additional sensors with the rx? or just plug the APM2 sensor pinouts to the rx for transmitting back to the radio ?

This is not the mod you want for that. I'll see if I can find a link to Earl's work. I believe that's what you want for the FrSky.
