I am trying to tune the ArduPilot for Bevrc X-5 plane. At the moment I am playing with roll P gain and trying to achieve acceptable stability in FBW mode. Also, I am trying to overcome the plane peculiarities: he has tendency to roll in positive…
I use exactly same configuration: ArduPilot + ArduIMU + MTK gps,
and kind of home-brewed OSD to visualize ArduPilot output.
Sometimes I observe the same behavior: solid blue led on AP board
(what indicates that AP thinks that it…"
"In order to get ArduPilot_2_8 compiled with GPS_PROTOCOL_IMU, I needed to make following changes:
* add gps driver initialization to lines 54 -57:
#elif GPS_PROTOCOL == GPS_PROTOCOL_IMU AP_GPS_IMU g_gps_driver(&Serial);
* replace obsolete…"
"Thanks, Jason, I will try to reduce the nmea string buffer.
In fact, I have already moved in same direction: with emptied init_gps() and GSC_NONE,
nmea gps works fine. I have noticed that if size of result code is less than 26Kb, everything
works…"
However, from my point of view the missed semicolon is a minor problem. Main issue seems to be
an AP hang at initialization phase, when NMEA gps is enabled.
I found that removing any…"
I tried to use NMEA gps with AP2.7 (svn revision 1272) and run into a strange problem:if I set GPS_PROTOCOL to 0, and load resulting code into AP, then AP failed to init.In the serial monitor I can see only few first lines of the initialization…
I have tried to update AP sources, and found that revision 1232 introduces strange throttle behavior: when I switch to satbilze or fbw_a mode, motor spins with full speed (disregard throttle stick position). It works fine in manual mode though…
