Re: [Paparazzi-devel] Strange Servo Deflection Problem

[Helge Walle]

Hi,

It seems you have the opposite order on ch1 and ch2 compared to my Futaba 10CG in 7ch mode. could that be the problem?

This is my radio file:
<!DOCTYPE radio SYSTEM "radio.dtd">
<radio name="T10CG7" data_min="900" data_max="2100" sync_min="5000" sync_max="15000" pulse_type="POSITIVE">
  <channel ctl="right_stick_horiz" function="ROLL" min="1936" neutral="1525" max="1110" average="0"/>
  <channel ctl="right_stick_vert" function="PITCH" min="1107" neutral="1520" max="1933" average="0"/>
  <channel ctl="left_stick_vert" function="THROTTLE" min="1107" neutral="1107" max="1933" average="0"/>
  <channel ctl="left_stick_horiz" function="YAW" min="1929" neutral="1516" max="1104" average="0"/>
  <channel ctl="switch_G" function="CALIB" min="963" neutral="963" max="2069" average="10"/>
  <channel ctl="VRA" function="GAIN1" min="964" neutral="1489" max="2070" average="0"/>
  <channel ctl="switch_C" function="MODE" min="2072" neutral="1511" max="967" average="10"/>
</radio>

Helge.

Andre,

That is correct, I'm building against paparazzi dev branch. I believe
the radio channels are correct because the sticks all correspond to
what I want them to do. Left stick vertical is throttle while
horizontal is rudder, right stick vertical is pitch while horizontal
is roll (the only thing that is off is that pitch down only moves the
control surfaces down about 5% of the control surface movement when
pitching up.) The only thing I don't know about is any of the
switches, they don't seem to correspond to anything I've set in the
T7cap configuration since currently switch B controls the APs mode.
You are right about the autopilot section looking funky, our aircraft
is a VTOL fixed wing so for AUTO1 we'd like to fly it with a certain
altitude or just hover at a certain attitude. We haven't actually been
able to test those AP modes since we're still trying to get it to fly
in manual. Any thoughts or comments on the servo deflection, or
anything else for that matter would be appreciated!

Best,
Chris
