Code for using the Spektrum Satelite remote RX only #4

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
- Spektrum satelite remote model number: SPM9545
  -signal wires: White=GND; Orange=3.3V; Gray=Signal 
- The Mikrokopter and X-BL Funpilot have developed code for using only the 
satelite RX with a DX6, DX7 and the Futaba and JR TX modules. We should be 
able to do the same. 
- Benefits: Lighter RX. Cost $29. Diverstiy 2.4Ghz RX. 
The composite PPM signal would hook up to a pin on the K12 connector, but 
would need a Vcc of 3v. 
How to modify the irq.c and possibly the UAVX.c file: TBD

- More data on the Spektrum remote: 
The receiver satellite channel data is 16-Bit digital serial with no timing 
pulse.
At the beginning of the stream, generate a square wave signal which would 
ordinarily 
come from the main RX to connect with the satellite to find the EEPROM byte 
which 
sets the next set. This sets the EEPROM byte which sets when the next switch 
and 
then sets the RX-line directly at the beginning for low output, waits (approx. 
ms) 
and then goes high again for input.  You can do this to create a TX/RX binding 
button, or just bind the TX/RX outside of the UAVP software.

ReM provided his Spektrum remote satellite solution and is alowing me to post 
it here.
___
His info:
Yes, you can add to Google Code UAVX WIKI.
C1, C2 - 33 pF
C3, C5 - 200-500 nF
C4 - 10 uF
Z1 - 11,0592 MHz
IC2 - any 3,3V regulator
JP1 - to Spektrum satellite
JP2 - for mega8 programming
JP3 - to K12 on UAVX board

First bind satellite to AR7000 receiver.

If receiver lost signal, all channels give last time positions. I could have
programmed fail safe, but need some ideas how this should work.

I will answer all your questions...

Channels order as Futaba. From UAVPSet menu select "Futaba Thr 3 Sw 6&7".
