IR Sensors connection Cable

Pay attention when connecting the IR-sensors: It's not allowed to exchange the ends of the cable. The pinout at the sensor board and the Tiny is different!

after that: Airframe_Configuration#Infrared

uBlox GPS 5H

It is necessary to modify the airframe config-file ("-DGPS_USE_LATLONG") Airframe_Configuration#GPS

In the newer Airframe Config File this has to be:

  <define name="GPS_USE_LATLONG"/>

in the firmware section otherwise you might get the error:

  Invalid_argument("Latlong.of_utm")

flixr 23:02, 28 December 2010 (CET) You do not have to add the define GPS_USE_LATLONG, just use the proper gps subsytem: <subsystem name="gps" type="ublox_lea5h"/>

Sound Output

I just found out, that the Ground Control Station can "speak" some messages. This is very useful for the battery low warnings: Speech

PPM Output

To activate the PPM Messages in the new airframe config insert:

 <define name="TELEMETRY_MODE_FBW" value="1"/>

to the firmware section.

Using Graupner MX-12 for paparazzi

The MX-12 has 6 channels but no 3 state switch. To use it together with paparazzi I used a trick. I used the integrated mixer to mix 2 switches together into 1 channel. One swiches Auto2 on and off. The other switches between Manual and Auto1. The mixer setup is as following:

 MX 1: GEA -> GEA
 OFFSET 0
 0%  -100%
 SW AILE D/R

I hope that this is all that has to be done.
