Dual Rx input insanity - Herelink and RFD900x SBUS passthrough

RFD900x passing through SBUS on standard RCIN
Herelink on Serial 5 (from X9E)SERIAL5_BAUD - 57
SERIAL5_OPTIONS - 8
SERIAL5_PROTOCOL - 23SBUS on serial 5 is being inverted externally
Am unable to use a failsafe setting on the aircraft or it looses its mind and gets into a failsafe loop.
FS_THR_ENABLE - 1 results in the start of the loop, FS_THR_VALUE has nil effect.
If I leave the herelink off, and powerup the secondary transmitter, it works and RC input is seen, however aircraft still remains in failsafe.
If anyone wants a new ringtone, feel free to rip it

Does “Log”-> “POWR”-> “Vcc: Flight board voltage” measure the voltage from the battery to the flight controller via the power module?
And what voltage does “VServo” measure?

Loiter turns radius not working as expected
@myozone wrote:
I’ve been playing with the simulator for a quad and found Loiter turns radius doesn’t work. If I set 0 I expected it to do yaw turns in it’s own length or with a radius to whatever, but it seems to stick at a fixed amount or no difference at all, never zero.

Copter gimbal control problem
@XinChengGe wrote:
Hi everyone!
I have a gimbal camera, which doesn’t support sbus, mavlink.It’s only support a custom serial protocol, But I want this gimbal worked with arduCopter, I have few ideas.
Read the PWM output through a arduino, then convert to angle data send to the gimbal, But I don’t how to calculate the angle with the pwm value
I notice that mavlink support a gimbal protocol. It’s should possible to read the angle data through the mavlink, Just like the Storm32, But I’m not good at code.
Any idea will be very helpful.
Thanks!

Recommended Hardware for a simple waypoint mission
@TonyTheKiwii wrote:
DIY fishing Kontiki Catamaran– I want to be able to enter the coordinates for a single waypoint and have the Kontiki go to that point & stop. Recovery is then by electric winch. I anticipate external GPS/Compass module/s and ESC ‘Skid’ steering using twin thrusters (One in each hull). Could any members please suggest recommendations for the simplest controller hardware that would be best for this purpose. The sheer volume of controllers is confusing. Thanks in advance.

SkidBoat: Manual&Acro are working - Loiter,Auto&RTL are not working
@Quaxwilly wrote:
I have three planes with ArduPlane running, so I’m a little experienced with that.
Now my first ArduBoat is a skid-boat.
With that boat I have the problem, that the more or less manual modes (Manual&Acro) are running good, but the modes with automatic throttle are not running.
If I switch to one of the automatic-throttle modes (Loiter,Auto&RTL), the boat is turning to the desired direction (skid-turn), but it’s not accelerating forward.
On the OSD I can see the direction and the distance to Homepoint, so GPS is working correctly. And there is no error-message on the OSD.Maybe it’s one parameter I did not set correctly, but I can’t find it.
I have that behaviour with “ardurover4.0.0_OmnibusNanoV6_26.11.2019stable”
and with “ardurover4.1.0dev_OmnibusNanoV6_20.03.2020latest”.
Here are my parameters:

Elevon yaw and pitch are swapped in stabilize mode
@fpv_duck wrote:
Hi,
So my tiny delta wing seems almost ready to fly, except that when I move her around she tries to stabilize on the wrong axis. When I change the pitch the elevon move in opposite direction like they’re trying to compensate yaw, and vice-versa.
These axis were also swapped with my remote control, and I had to change the RC Mapping.
The virtual HUD moves on the right axis so it doesn’t look like an FC orientation (I have the arrow on the top, pointing left of the plane and I selected Yaw270)
Here’s a quick video that I did to show the pb: https://www.youtube.com/watch?v=PLAXYUm9bps&feature=youtu.be
Any idea what could be happening?

Is acro really acro?
@R.S.T wrote:
I’m flying a pixracer cibios with 3.6.9 for quite a while and simple acro works. There is some kind of difference between pitch and roll flips. Roll looks better than pitch. So I tried 2 rolls in a row. See the surprise:
after one and a half it stopped rotating even the roll stick was still completely at the end. I pushed the throttle to give it more power but it was dizzy so I couldn’t get back control
Any idea?

RE: Compilation Errors While Compiling and RC 4.0 for the BBBlue
@De_Funct wrote:
Hello,
I seem to be getting many compilation errors while compiling on a 32-bit arm computer. I am compiling RC 4.0 from ArduPilot on the BBBlue to see if things work out or if there are errors to be found.
Anyway…there is a better way. I am not taking that route right now.
Are there any plans to use waf w/ Python3 to compile RC 4.0 on armhf boards?
Seth
P.S. I see some libraries are still only compatible with Python2 from a guide I have been following. There is a new image available online from the beagleboard.org/latest-images people. The image is good. I am just seeing error after error and wondering if I should downgrade to an older RC or if anyone else is having compilation issues, too.

LSM9DS1 IMU Driver I2C Functionality?
@playertr wrote:
Hello,
I’m porting Ardupilot to custom hardware built around a Raspberry Pi Zero W. In order to keep my hardware plug-and-play, I need to resort to an I2C connection for my LSM9DS1 IMU. Because I’m building for a sailboat, I don’t think the additional loop time will compromise control stability. It looks like the current LSM9DS1 drivers don’t have compatibility with I2C, unlike the Invensense drives. I’m a new developer working through the APM onboarding documentation, and I think LSM9DS1 I2C support could be a good first feature for me to implement. Based on the device datasheet and other drivers, this addition looks straightforward but I’m concerned there might be more nuance which prevented I2C support from being added in the first place. I want to ask other developers before I start:
- Is I2C too slow for most APM vehicles, or is there another reason that the LSM9DS1 does not have I2C support?
- Would LSM9DS1 I2C support be a welcome addition to the codebase?
- Should I do another project first that is a more suitable first exposure to APM’s HAL, macro usage, and threading support?
Thank you very much!

Large drone stability problem
@MarcinRC wrote:
Dear colleagues,
I need help because I don’t know what to do anymore.
I have a drone with the following specifications:
Frame - 105cm
Engines - T-motor U8 Pro
ESC - T-motor Flame 60A
T-motor 26x8.5 propellers
Battery - 8S 16000mAh
First, I brought the drone to a state so that it could perform autotune, and then I did autotune for each axis. The drone on a windless day flies very well, but when it starts blowing at a speed of more than 4 m / s it is very unstable. I tried to improve it, but unfortunately nothing brings positive results. Can any of you advise me on this matter?params.param (18.0 KB)

RFND and DPTH log do not work with ArduRover 4.0
@aproof wrote:
Hi!
I’m connected my sonar (over NMEA on 10 Hz) to Pixhawk1 for bathymetry (bottom mapping).
But log data (RFND and DPTH) is not written to DataFlash on ArduRover 4.0 (but on ArduRover 3.5 it works great for RFND). The LOG_BITMASK is check for the RANGEFINDER.
However, my sonar and ArduRover 4.0 work perfectly, which can be seen by telemetry.
Is this a bug or a feature?

Well flown 500mm quad not used over winter. Upgrade to 4.0.3. Flew a few times, (50 mintues), then it crashed during slow climb in loiter. Symptoms of a motor stop. All still seems to work OK after landing gear repair. I can see a tumbling motion in the log. How do I look at motor drive from the logs? Anglian

Does BLHeli32 DShot and Passthru support work on I/O PWM OUT on Arducopter 4.0?
@marstonstudio wrote:
I am about to solder together my Tekko32 F3 ESCs to the power management board for my Pixhawk4 ( specifications here http://www.holybro.com/product/tekko32-f3-esc-35a/ and https://docs.px4.io/v1.9.0/en/assembly/quick_start_pixhawk4.html )
A year or two I had put together a similar configuration with Arducopter 3.6 and found that I needed to use the AUX out ports on the board which support FMU if I wanted to have DShot and Passthru support. Checking the page at https://ardupilot.org/copter/docs/common-blheli32-passthru.html I see there used to be a warning
DShot and BLHeli_32 features are currently only supported on the “FMU” outputs of your autopilot. Boards with IO coprocessors like :ref:
Pixhawk <common-pixhawk-overview>and :ref:The Cube <common-thecube-overview>provide DShot and BLHeli_32 support only on the AUX OUT ports that are directly driven by the board’s main processor.but that warning was removed on Feb 2, 2020 ( https://github.com/ArduPilot/ardupilot_wiki/commit/35faf235a4628b3dbb8f9faff88782738e697d4b )
Does this mean that if I wire my ESCs to the M1,M2,M3,M4 I/O PWM OUT signal pads on the Pixhawk 4 power supply board that I will be able to use BLHeli32 DShot and Passthru?

Vibration, frustration and crash with 450mm
@Tavero wrote:
Hi there,
First of all, while I’m not new with GPS quadcopters, this is my first quad that is running Arducopter on a Pixhawk clone. So a few weeks ago I finished building this 450mm quad and installed balanced 10" props, upgraded the firmware to 4.0.3 and did a few test flights. While it did flew somewhat decent, I had issues with oscillations and vibrations. Mainly in the Yaw axis.Then the frustration began. For weeks i tried to tune the filters and PIDs, did AUTOTRIM and AUTOTUNE but i had the feeling, that it was flying worse and worse with everything I did.
Just right now the “crash” happened . When I wanted to take off in alt hold mode, the quad just tipped over and shredded 3 out of 4 props and the gimbal to bits, severed some cables and also probably damaged the Lipo. Disarm didn’t work and I had to disconnect the battery, so i dont have any logs, but the Pixhawk probably wouldn’t have saved anything anyway because I didn’t left the ground.
As of right now I’m close to disassembling the quad and dropping the project. I only had one spare pair of 10" props so I guess I won’t be flying this quad for the next month anyway. But I still want to know what the hell happened, why it just tipped over, and how I can prevent it the next time.2020-04-09 17-12-10.tlog (765.2 KB) parameter backup.param (17.9 KB)
Can anyone just take a quick look at the logs. Maybe there is an easy to see mayor flaw in my parameters?
regards TavEdit: Seems like i can’t upload all my logs. Because of size?

ANN-MB Antenna Magnet v.s. Compass
@Dave_Sid wrote:
I just started playing around with the Ublox F9P using their developers kit which includes their ANN-MB antenna. This is for a rover application. The antenna has a big magnet in its base which it uses to stick to a ground plane. Does anyone have any experience, thoughts or advice regarding how this might interact with a compass?
Thanks,
Dave
