Hello all!
With your help, I made some progress. Thanks again. Not
surprisingly, more questions have arisen.
1) Xbee:
I got a pair of 2,4GHz xbee's for at least until the duty cycle
issue is solved. Maybe it is even illegal to use more than 10% duty
cycle with the xbee 868. The 2G4 modems work great, so far.
2) Calibrating the IR's:
I put the sensors in a styrofoam box and got the readings from the
messages window. The horizontals were around 300, while the vertical
was zero and increased slowly. They all drifted. Is this normal? If
yes, should I wait until they stop drifting or should I take the
inital values, or average?
3) IR sensor orientation
I'll probably find out which thermopile is which, but I did not find
any hint on this. Which one is the top, which is the bottom? Which
is the fore, aft, left and right sensor? I mean mechanically, for
mounting on the airframe.
4) Battery voltage:
I connected a 3S lipo battery with roughly 12V, but the GCS reports
something like 8V and in the terminal section I get messages like
catastrophic lo batt voltage.
Do I have to adjust something?
5) Servos:
I tapped the receiver and I am able to switch to manual, auto1 and
auto2 modes with the transmitter. I connected a servo and expected
to be able to control it in manual mode by moving the transmitter
sticks.
Tried different servo connectors on the Tiny, no luck.
I am using the original funjet1.xml (which I will have to change
because I will not (yet) fly a Funjet). In the messages window, I
can see that the actuators react to the movement of the sticks.
Tried to see the PWM signals on the scope. Did not see any pulses,
all of the servo signal pins were constantly hi.
Since I was indoors, I did not have a fix. Do I have to wait until I
get a fix before attempting to control the servos?
Greetz, Martin
