Does not react to Joystick in Manual mode

Hello. I have a weird problem since a bit more than a week.
We have been using a Logitech Game pad controller to control our USV. Its a build with two motors, very similar in concept as rmackay9 built and used to show the loiter function in this little video here: https://ardupilot.org/rover/docs/loiter-mode.html
First problem I encountered (after updating to the latest MP) was that the button assignments forthe Joystick where not showing anymore (the right side of the Joystick window)… weirdly enough they were still assigned correctly.
I have now reverted back to the .68 MP version and the joystick buttons all are labeled corrected.
So here is my problem:
When I switch to Manual mode and increase throttle on my Logitech Joystick, nothing happens. There is no change in Servo output 1 or 3 (skidsteering). Also left/right does nothing. When however I switch to Loiter mode the rover reacts as usual, trying to keep the rover inside the loiter radius by engaging the motors.
I did a motor input check and the outputs are assigned correctly. I have attached the log file.

Any help with this is deeply appreciated to make it work again! (It did work before!)

HereFlow and secondary rangefinder

I recently got the Hereflow sensor to do GPS-less navigation. Since the lidar on the module is only good for 2m I added an LW20 as a secondary lidar. When I connected it and set the parameters noted in the documentation it didn’t work. I tried multiple combinations and it seems like you only can use one rangefinder with the optical flow, not both. Can someone explain why this is?

Adding Extra UART to Omnibus F4 Pro by editing hwdef file to repurpose RSSI and PWM5

Following this RCGroups post I am trying to add an extra UART to my installed Omnibus F4 Pro V3.
https://www.rcgroups.com/forums/showpost.php?p=39970238&postcount=274

RSSI and PWM5 can be repurposed by editing the hwdef file it seems.

These are the instruction the RCGroups poster offered:

In hwdef.dat add UART4
UART_ORDER OTG1 USART6 UART4 USART1
PA0 UART4_TX UART4
PA1 UART4_RX UART4
Finally remove the RSSI (ADC) and PWM5 definitions.

This looks nothing like the hwdef file I can find in my target folder. This file is a .h file while the poster makes reference to a .dat file. Am I looking in the correct place? Can anyone give me pointers?

Using QGC v.3.5.6, I just loaded ChibiOS - Heli: ArduCopter V3.6.11 (stable) on my brand new mRo Pixracer R15. I was expecting to pick an airframe from a page of colorful graphics. Instead…I was presented with this menu for airframe selection:

I have NO CLUE what a traditional flybarred 450 sized heli should be classified as far as FRAME TYPE. Could not find answer in the Wiki nor this site. Help anyone?

For giggles, I erased the Arducopter Flight Stack and loaded the PX4 firmware. At least QGC presented the cool graphics I expected:

BUT…
For traditional heli, the ONLY choice was a Blade 130x…no other traditional heli options?
What am I missing?
For the record…I plan to use ArduCopter flight stack after I get over this hurdle.

Thanks to all,

@fnoop Hi! Just loaded Maverick and followed Quick Start setup instructions using a RPi 3 B+ with GPIO pins wired to Pixhawk 2.1. I get an Exception error when running mavproxy, so being relatively new at this, I’m hoping for some initial help to get me going. I tried reading through the older threads, but started to get a headache ; )

mavproxy.py --master=/dev/serial0 --baudrate 921600 --aircraft MyCopter

For starters, I’ll be happy just to talk to the fc. I haven’t touched the localconf.json file as yet. Many thanks

Copter-3.6.12 has been released! Critical Safety Update if you are flying 3.6.10 (or older)

Copter-3.6.12 has been released as the official default software for MultiCopters and Helicopters.

For those flying 3.6.10 (or earlier) the upgrade is Critical to avoid possible lockups due to I2C storms. These situations are rare but we have seen enough of them that we strongly recommend upgrading.

For those flying 3.6.11, your vehicle is probably safe but we still recommend upgrading to 3.6.12 because it includes a fix to another rare case of I2C storm lockups caused by extreme interference on the bus. We have one reported case which involved a serial port inadvertently connected to an I2C port.

The upgrade from earlier versions of 3.6.x should be relatively painless with no re-calibrations required unless you see pre-arm checks prompting you to do so.

The two new changes in 3.6.12 are in the ReleaseNotes and copied below.

  1. Fix ChibiOS I2C DMA error
  2. COMPASS_SCALE param to allow manual correction of compass scaling

The second issue allows users to work around a compass scaling issue with the Hex Here2 GPS/compass unit. The Here2 compass unit’s scaling is off by about 17% meaning setting COMPASS_SCALING = 1.17 should improve accuracy. The accuracy can be checked before and after this change by:

  • fly the vehicle in any mode but ensure the flight includes chaning the vehicle’s heading
  • download the dataflash log and check the NKF4.SM values which are the compass’s “innovations” (the difference between the expected values and actual values). Lower is better so hopefully Here2 users will see lower values after setting the COMPASS_SCALING value to 1.17.

Note: beta testing of Copter-4.0.0-rc3 will resume next monday (Dec 16th).

The official announcement is here but please note that for users of 3.6.10 or earlier this is a CRITICAL UPDATE because of the risk of I2C storms that can cause a lockup in flight. These are rare but we have seen enough of them that we strongly recommend users upgrade.

The upgrade from earlier versions of 3.6.x should be relatively painless with no re-calibrations required unless you see pre-arm checks prompting you to do so.

Sorry for the troubles but thanks very much to those who reported the issue and helped us get to the bottom of this!

I ask for help in assessing the acceptable level of vibration, for example, what permissible boundaries on the Vibe tab should be that the aircraft is armed and in flight vibration does not interfere with steering?

Ola, eu sou o Danrlei
eu tenho um kit 3DR de telemetria 500mw, minha pergunta é se de alguma maneira tem como conectar dois desses kits no Navio2 de forma que funcione como um espelhamento de rádio deixando eles em paralelo se por acaso um cair a conexão o outro assumir, ou como funciona com o GNSS sempre escolhendo a opção de melhor sinal, eu quero ter redundância nos rádios pois os equipamentos são muito caros para não ter uma redundância também na comunicação, como existe na bússola, fonte e GPS.
Eu pensei em ter dois rádios no navio2 e dois na estação de base.

RTK with different Base and rover receivers

@PavelPavlov wrote:

Hi guys,
I am using Mission Planner with EMLID NAVIO2+. I am trying to arrange a RTK configuration as an experiment. I have survey grade GNSS receiver E600 of E-survey as a base station (as some from Leica and Trimble too). It provides multi frequency and phase data from GPS, GLONASS, BEIDOU etc… I connect it via serial cable. Mission Planner shows everything right in the Injection window - the messages, the satellite graphs and for the last example the Base, GPS, Glonass and Beidou markers lighted in green.
At this experiment I am interested in the possibility of connecting Base and Rover from different producers. I am in the process of purchasing the Rover receiver and I am hesitating between Trimble/Septentrio or some cheeper solution as Picsi or Sirius. At this moment I am not very interesting in RTK. More important is to have 1 cm precision of the camera position and it is better be in PPK.
I will appreciate any advises on this.
Thank you

I dont see a current spike, thinking about a shortcut some where.

When the drone was on the ground after the crash, I hear a little sound from the speaker, like tok, tok, tok. The cube was energized, but like stuck. How can I realize if this was because the bug reported on the SB5?

http://190.100.113.54:16211/archivos/logs/04112019Crash.zip

Finaly here is a video of a strange sound of the Cube at the startup. This sound always be there, even before the crash, but no other cube I have make that sound at the startup

Wraith32 ESC and Pixhawk - Motors 1&4 dont spin 2&4 do

@Tampa_Drones wrote:

This is a fresh build and had everything working last night. I got hung up a little before finding one of the escs was on older firmware, so after syncing and updates, I was successful at hovering last night. It was almost midnight so I put everything away for the morning. Today I go out to attempt another flight and autotune, and now only motors 2 and 4 spin. Motors 1 and 4 dont spin nor do they chirp as usual. I checked and they are getting power and continuity is good from the esc to the pix. Swapping motor 1 to motor 2 yields no response. I can however plug 2 into 1 and get the usual tones. Can 2 secs just go out like that?

AT Pitch - Ready to throw this thing out the window!

@Itmac79 wrote:

I’ve been working on a few AT projects this past month, and can use some help. I have no previous experience with coding, and have figured everything out on my own so far with the help of this forum.

Through way to many hours of trial and error, I got it to work for Pan, but getting the pitch to work has me ready to scrap the whole thing.

I’ve tried using postion and continuous rotation servos for the pitch. I was never able to get the position servos to work right. I recently switched to a continuous rotation servo (HSR-2648CR) and somewhat had it working. It would accurately track a sim plane at altitudes above 200m, but not below, regardless of PID or max/min pitch settings. After taking a break for an hour, I fired it up again and now I can’t get it to track pitch at all.

I would welcome any suggestions! My setup is below. Please note, I changed the layout after the photo. The PX4 now sits on the tilt frame and moves with the pitch.

I also would like to know how to disable the internal compass on the PX4 and only use the external compass in the GPS puck, so that I can swap them so only the GPS puck moves with the pitch.

Physical Hardware Setup

•Custom designed gimbal frame, 3D printed
•Pixhawk 4 Autopilot w AT 1.0 firmware
•Mission Planner, latest release
•Hitec HSR 2648 continuous rotation servos for Pan and Tilt.
•Holybro sik Telemetry (vehicle to AT)
•OLED display on i2c.
•5000mah 3cell lipo, PX4 power module, Castle creations 10 amp BEC @ 5v feeding the servos.

For the Sim:

•I run two separate instances of MP with AT firmware on the computer.
•One connected to the tracker via USB for adjusting parameters.
•The second running the same AT firmware Sim with Plane, circling my house at various altitudes with a radius of 200M. MavLink telemetry from Sim is sent to the actual tracker via a Sik radio connected to computer via USB.
