can someone help me in setting up the parameters to get this to work with Ardupilot? I have been trying this for several days and can not seem to find a solution.
The motor is connected as follows (only testing one motor now to make it work … This is why I am only specifying the connections for one here):
Vcc: +12V
GND: GND
CW/CCW: Relay pin 1
PWM: Servo 1
I am using pixracer board. I update the firmware via QGroundControl Software. After uploading the firmware, The EKF2 parameters are not running in my board. I cant able to calibrate the Level Horizon sensor calibration. Even, I can’t able to see the machine orientation in Head up Display. It is simply stable.
I’m setting auto-landing parameters using mission planner on my V-tail plane. I’m using pixhawk 2.
My confusion is that the LAND_FLARE_ALT(set to 2m) and LAND_FLARE_SEC(set to 3m) sets the descend rate of the plane once it’s at flare stage, which calculates to 0.67m/s. However, the TECS_LAND_SINK(set to 0.25m/s) parameter also sets the sink rate of plane, so that it has a smooth touchdown.
so what parameter will the plane follow if both values are different?
Hey everyone. I’m on the hunt for a battery connection solution to create a secure but easy to swap battery. Similar to what you’d find on a Mavic. Has anyone had experience designing a system like this?
Looking to give the Lua interface access to the on-board ADC. Giving methods such as get_voltage and specifying which channel (6.6 or 3.3). Not sure how to go about this, looking for what steps to take to add this custom binding
In the latest version of firmware (arducopter trad heli), with the latest QGC there is no longer an option to set channel 8 to throttle output so I cannot tie throttle output to a knob. This is how I normally fly, I arm, and raise the throttle (with collective pitch at zero) using a knob I programmed into my radio as channel 8. This allows me to have a constant speed at any pitch and is the only way I fly 3d in acro mode. This allows me to adjust the throttle speed at will but its no longer in the menu for “heli”. I had to roll back to QGC 3.5.6 and it returned, but I had to re-flash the older firmware (arducopter-heli-stable-3.6.12) manually as ver 4 had tons of missing parameters. I do not like manually flashing firmware, I prefer to have QGC find the right fmuv2 version firmware on its own and flash it as its safer than manual updates.
Is there any reason for this change and I missed the note somewhere? I cannot use arducopter without this ability and I tried to map it through the full param list but it didnt work. I left it on the older QGC and older firmware but ideally I would like to use the latest version.
Below is the version I am forced to use with the latest QGC and the missing option in ver4:
Thanks in advance and let me know if this is already known and being worked on or if I should report it as a bug somewhere (but where)? I am fine now because both my T-Rex 600 Pro DFC and T-Rex 700 DFC are both using the older firmware (which has the option enabled so all works fine) but I am on the older firmware (3.6.12 and QGC 3.5.6) so I am not on the latest builds of either but would like to be ideally.
NOTE, I now realize that my second picture shows FMUv3 (thats my 700 and was used to show the older firmware RSC channel 8 knob option), my T-Rex 600 Pro uses FMUv2 so thats all accurate.
I’m controlling a release mechanism with a servo on a kakute mini. When I tried to use servo5 it made the servo hot and made it go to it’s endpoint. When I used servo6 instead, it works perfectly. Has anyone else experienced this with a kakute mini? I’d think that servo5 and servo6 should behave the same way.
Pixhawk 4 from Hollybro
Running 4.0.2
I flew several packs this morning with no issues what so ever. I went to fly again later, and had no throttle output.
When the hardware safety switched is pressed, the ESCs react accordingly, so there is obviously some kind of signal output.
I’ve tried:
re-calibrating the radio
re-installing the firmware
using a different ESC
using the same TX with a different drone (armed and flew no problem)
using the motor testing tab to control the motors
All with no output. Everything looks to be working in Qgroundcontrol. I can’t find any info on anyone having a similar problem. Any ideas? I think I’m going to try to downgrade the firmware first.
Is it possible to use Mission Planner’s tiling engine (GMap to obtain georeferenced tiles that it stitches together across multiple formats, e.g. GDAL) with my own code to draw courses, instead of drawing them using click-by-click waypoints onscreen? Perhaps a callable “MPTiler” external library exists that incorporates MP’s significant advances over GMap?
Copter-4.0.3 has been released as the official/stable version for multicopters and traditional helicopters and can be installed using one the GCSs (Mission Planner, QGC, etc) or can be directly downloaded from firmware.ardupilot.org/Copter/stable.
Changes vs 4.0.2 are in the Release Notes and also copied below:
Bug Fixes:
a) “RCInput: decoding” message watchdog reset when using MAVLink signing (Critical Fix)
b) HeliQuad yaw control fix
c) Do-Set-Servo commands can affect sprayer, gripper outputs
d) Partial fix for BLHeli passthrough fix for H7 boards (CubeOrange, Holybro Durandal)
USB IDs updated for “composite” devices (fixes GCS<->autopilot connection issues for boards which present 2 USB ports)
RCOut banner helps confirm correct setup for pwm, oneshot, dshot
ZigZag mode supports arming, takeoff and landing
The most important fix is the first one which can lead to the autopilot rebooting (via the watchdog ) when the RC transmitter is first turned on but only if MAVLink2 signing is enabled. We are not aware of any crashes caused by this issue.
Thanks very much to the developeres and beta testers who contributed to this released! Thanks!
My 250 size quad is running Open Pilot Revolution board (non Pixhawk board) using ChibiOS operating system. When switched to loiter mode, the quad experiences toilet bowl effect. I use default setting (param attached) after flashing the firmware. The built-in compass in the Revolution board works fine as witnessed by the correct display of direction on the HUD of MP corresponding to the direction of the board, Pls see attached photo on the layout of the quad.
I have another quad 450 size,. FC is Pixhawk running arducopter V3.6.1. This quad works satisfactorily in loiter mode, and it uses mostly default settings.
GPS connected to Pixhawk normally uses NMEA as protocol. Now that the board is ChibiOS board, could it be the toilet bowl effect due to malfunction of the mini ublxo NEO-6M GPS because it is pre-configured to UBX instead of NMEA ?
Can anyone help to trouble shoot the problem with the attached param of the quad 250 ? DF log is not available because there is no memory card on Revolution board. Quad250.param (13.7 KB)
Hi is there a way to setup a single channel for 3 difrent functions .
For example setup a channel X for controlling 3 functions on a camera so between 1000 and 1300 camera starts video. Between 1300 and 1600 camera focus. Between 1600 and 2000 camera trigger foto. It wood be verry intresting if ardupilot coud setup the channel option like betaflight. Resson is that we most of the time use sbus and we can pasthroug sbus on the sbus out pins and these days the camera controllers on the marked also use sbus with a single channel for controlling video, focus and photo trigger. Hoop in the future this coud be a possebilety and it woud make a big diferece for proffecional use case.
I am using MMWave Radar for Obstacle Avoidance and it working fine for Obstacle Detection. I can see obstacles in the Proximity Window of Mission planner.
Also, I am using the Pixhawk CubeBlack and ArduCopter V4.0.4 version.
The issue is that I can’t see Red Rounded Obstacle on the map of Mission Planner.
I’ve created an EAGLE library and reference schematic package for those who would like to design their own Cube Carrier board. This package contains production-proven footprints, easy to follow schematic symbols, and a known good schematic for the carrier board to start your design from.
I have Copter-4.0.3, but this was also observed on Copter-4.0.2, I tried the matek f405std board and got the same,
r9m and r9mm receiver.
settings as in the photo. on the calibration tab of the equipment, the values change depending on rssi and are on average 1800.
no matter how I can understand what the problem is
Copter 4.0.2 already the 2nd time all parameters gone! The first time it was after the update from 4.0.1 to 4.0.2, everything was set up again and wanted to fly today, everything gone… What can be the reason for this? I have to deliver the Copter next week, better go back to 3.6.x?
well, I have manage to set everything considering my Pixhawk 2.4.8. based hexacopter, but there’s one problem i cannot solve. Namely, I have connect my FPV and mini OSD (used wiring scheme from https://ardupilot.org/copter/docs/common-minim-osd-quick-installation-guide.html) and I have interference between them (see screenshot).
When I connect only mini OSD to transmitter without camera it shows all data crystal clear…also, when I connect video out from camera directly to transmitter, pic is clear…but after connecting camera through mini OSD i get interference.
I have an Ultrawideband system that tracks a tag attached to my drone. The tags output is processed by my own teensy 4.0 on the drone, which repacks its position into a GPS_INPUT message. This message is then passed onto my pixhawk.
This works, but I need to increase the precision as much as possible. My question now is, would it be best to do some filtering (using an EFK for example) on my teensy and send as precise of a location to ardupilot, or just let the EFK of the ardupilot handle this filtering?
Right now I seem to get better results filtering the data first myself, but I have hardly played with the parameters of the ardupilot EFK yet.
I want to use in one waypoint more servo command. In fishing we strive for accuracy. It would be good to have 2 or 3 servos work at a single waypoint at a time.
It would be nice if you do not need blank wp in the SET_SERVO commands.
Now in auto mode you need 9 waypoints in one mission with the same coordinate:
1wp wait 5s,
2wp set servo 5-2000,
3wp wait 1 sec,
4wp set servo 6-1000,
5wp wait 1sec
6wp set servo 5-1000,
7wp wait for 1s,
8wp set servo 6-2000,
9wp rtl.
This is a novel, and not so accurate. How wonderful it would be if you just went to the waipoint, stop, give the fish two container meals, the tank closes and comes back, it will be possible sometime?
