Started this discussion. Last reply by Robert Baumgartner Feb 13. 4 Replies

I've been working on configuring the ArduPlane firmware to handle joystick-only control a little better. So far all has been going well but now I've run into a bit of a roadblock with HIL simulation…Continue

I've been bench-testing my APM2 board and everything is working well enough but I'm noticing an issue with the altitude reading; it's all over the place!After initial startup the APM2 usually starts…Continue

"That's what I thought but thought I would ask anyway. u-Center is a much better program than the MiniGPS! Thanks for the quick answer."

"No it's not. u-Center is specially designed for uBlox chips and not to anyone else. "

Mediatek w/ U-Center?

Is is possible to test the Mediatek GPS w/ the u-center software? I've tried connecting w/ FTDI but u-center won't display any data (even though 3D-Fix light goes solid and u-center reports the connection as good; green-light blinking @38,400bps).Is there an additional step to make it work?See More

Robert Baumgartner replied to gregmaan's discussion Trim values from RC at boot time in 2.65 and 2.66
"That's correct when switching modes, but not at startup. trim_radio() does not check the TRIM_AUTO parameter (but it should!) so when called by startup_ground() it resets the values every time. The following code says it all: From…"

HIL Output from APM2?

I've been working on configuring the ArduPlane firmware to handle joystick-only control a little better. So far all has been going well but now I've run into a bit of a roadblock with HIL simulation (using X-Plane).Looking through the code it looks like MAVLINK_MSG_ID_HIL_CONTROLS is used to send the positions back to MissionPlanner, which then passes it along to Xplane inputs. My problem is that so far I haven't been able to find where the messages are sent out from ArduPilot. I found all the…See More

Craig Fraser replied to Robert Baumgartner's discussion Please help! APM2 Barometer/Altitude Issues
"The "altitude" reading will change for a given location as the barometric pressure changes i.e. the weather. Good luck if you think you're going to get an altimeter that's accurate to within a foot for $200, never mind attached…"
