Orange Cube - FrSky Passthrough and MOT_PWM_TYPE issues

Hi. Great times ahead :smiley: !!!

I’m having this issue on an Orange Cube. Tried setting FrSky Passthrough protocol (10) on Serials 1, 2 and 4 (Telem1, 2 and GPS2). With SERIAL_OPTIONS set to 7 and using a straight wire to X8R, it won’t work, no matter what I do. I tried both TX and RX pins on all three ports.
Using a regular serial port MAX3232 cable, with _OPTIONS set to 0, works only with a certain mix of BEC/USB power. It always works if USB power is applied first. It never works if BEC power comes first. If BEC power is applied, then USB, it starts working when BEC power is interrupted, and will keep working if supplied again and USB disconnected.

Now to MOT_PWM_TYPE… I have an APD ESC, which won’t take anything below DShot300 as input, unlike BlHeli_32 that run with classic PWM, as well. I’ve tried both 5(DShot300) and 6 (DShot600), and the APD esc wasn’t happy with the signal - on AUX 1-4, with reconfigured outputs, obviously - then analyzing two short flights with BLH32 yelded PWM values on C9-12 while protocol was set to DShot600

Funky calibration problem - ESC calibrating with steering, not throttle

@Pipy wrote:

I have built a catamaran using differentiated thrust to steer (first ever RC build). Everything was going OK, I had the boat sailing ok in manual mode, however the steering direction would flip when more than 25% throttle was applied (that’s an issue for another day). When trying to fix that issue I created a new problem. I’ve spent about 15 hours now unsuccessfully attempting solve this one so its time to seek some guidance.

Explanation of the problem:

• Port side (left) ESC/Motor connected to Chanel Output 1 only calibrates with Right Stick (Aileron) on transmitter.
• It only calibrates (emits 2 short tones and one long tone) when pushed to the PWM limit 984.
• It is unresponsive to Throttle
• I have tried manual, automatic and semi-auto resets about 50 times each.
• Transmitter is Taranis PLUS 9XD.
• Right stick is mapped to Roll on Mission Planner (not reversed).
• It’s not the motor nor ESC as I have tested them with spare parts and the same issue arises, so I know its somewhere in the flight controller settings.
• I haven’t changed any settings on my transmitter.
• SERVO1_Function value is 73
• SERVO3_Function value is 74
• Output Chanel 1 is the left motor (problem)
• Output Chanel 3 is the right motor (working)
• It doesn’t make a difference if the esc is connected through MAIN OUT 1 or 3
• No problems on the other side as Starboard ESC/Motor is calibrating to throttle as expected.

Any help would be much appreciated.

Trouble with SIK radio telemetry in mission planner

I just received a pixhawk 2.4.8 with a 915MHZ radio telemetry module. After plugging it in to my laptop and turning on the pixhawk windows wouldn’t recognize the telemetry module. After a great deal of trouble with drivers I manged to get my PC to detect the usb side of the telemetry as a COM. I figured this would be the end of it and the thing would work properly. The telemetries seems to be communicating with each other since I can load settings and upload firmware via the initial setup tab of mission planner but whenever I try and connect to the pixhawk I get a ‘no heart beat packet received’ error. My baud rate is correctly set at 57 and I can communicate with the board through a direct usb connection, so i’m not sure what the cause of the error is stemming from. If anyone has any solutions I would be very happy. I’ve been troubleshooting this for several hours now to no avail .

https://uk.farnell.com/molex/38-00-1395/socket-pcb-0-1-5way/dp/9732349

first up i have to change Molex plug as it was only 4 pin was installed on RDF 900x TXmod

then added the wires for the teensy

then added the wire from teensy pin Tx1 to bottom pin on rdf txmox molex plug

add a buck converter to drop V+ to 5+
i have found that teensy is little unreliable at anything over 5.1

flashed with Mavlink to FrSky S.Port Passthru Converter By Eric Stockenstrom

covered it up heat srink

put it all back to together

Then go to this project add it to openTx on taranis X9D or the horus X12S

fired it up on the Taranis X9d first

works great on the taranis x9d now to try the horus x12s

thank you all

Turning light On/Off with MP and a PixRacer

@sailordude wrote:

Hello! I have the following AutoPilot build:
PixRacer (6 Servo pins) with a Mauch Power Module. Servo 1 and 3 are used for controlling to motors (differential Steering).
I would like to turn a 12V light On/Off via Missionplaner. For this I have a Mosfet Relay which can be triggered with a PWM signal. https://www.aliexpress.com/item/32785122281.html?spm=a2g0s.9042311.0.0.27424c4dZgC01z

The idea is to hook it up to Servo 4 and send a PWM signal when I want to turn it on (the Mosfet Relay then lets the 12V through to the light).
Here is my question:
What Parameters do I need to set on ArduRover 3.5.2 in order to make this happen and how do I actually control it via MP? I also use a Logitech Joystick, so I would like to able to configure one of the buttons to turn it off on.
Thank you for your help!

PEMFC stack direct drive, without DCDC and LiPo Batteries.

Two types of stacks:
1hp stack: rated output power over 800W, total weight of 1.6kg.


2hp stack: rated output power over 1600W,total weight of 3.3kg.

Totally integrated controller, easy to use: provided 50~70kPag H2, output electric power immediately.

Battery 1 monitor is used to monitor the output voltage and current of the stack.
Battery 2 monitor is used to monitor the hydrogen pressure inside the cylinder.

Duration of more than 4 hours can be achieved with a 10X camera on a 3-axial gimbal.

I am having an issue getting the Compass to Calibrate on version 4 when I am the copter a message appears on the ground station telling me the compass is not calibrated. The Copter is running on a Pixhawk 4 and Here GPS.

I have tried several version versions of the Developer edition and could never get the compass to calibrate. Each time I do the calibration the values are almost the same. When I load the previous version of copter everything works fine.

Summary of ArduCopter stick gestures?

$

@ghawkins wrote:

Is there a page that summarizes in one place all the standard stick gestures, i.e. actions you can perform via the sticks of your TX? The ones I know of are:

  • Arm - throttle/yaw to bottom left (arming docs)
  • Compass recalibration - throttle/yaw stick to top right (calibration docs)
  • Lost copter beep - roll/pitch to bottom left.

I came across the lost copter beep by accident (and only know that it is the lost copter beep because you see a message telling you so in the MissionPlanner log). I think I’ve seen that you can also recalibrate the gyro via the sticks but forget where and what stick positions are involved.

Are there other stick “gestures”? And are they documented somewhere or are they just common(ish) knowledge within the community?

Sorry if this is already covered in a previous post here or a wiki article or in the documentation - Google didn’t help me find such a page.

Configuring relay switch on F405 for camera switcher - RCx_OPTION unavailable

$

@jpgoblin wrote:

I’m trying to figure out how to control a camera switcher (Bick’s Multiview Duo) via a switch on my remote so that I can have a downward facing view during flight. The camera switcher looks for a PWM signal for 5 seconds after being powered on; if it doesn’t see a PWM signal within that time, it expects a digital signal. Since the F405 board takes longer than 5 seconds to boot up and output PWM signals, I have to figure out how to output a digital signal to it (if you can think of a way around this that doesn’t include a mechanical power switch, let me know).

The F405 is running V3.9.11 with BRD_PWM_COUNT = 4 and RELAY_PIN2 = 54 (corresponds to PC8 TIM8_CH3 TIM8 PWM(5) GPIO(54) pin from the “hwdef.dat” file). I believe I’m on the right track, but I can’t figure out how to control that pin from my remote. It appears that Arducopter has a RCx_OPTION where a radio input can be mapped to the “Relay2 on/off” option, but arduplane has no such feature. Any ideas on how I can get around this?

Unnecessary high throttle in Feb and cruise

@Kyle_Larson wrote:

Hello, I’m having trouble with my mini talon and alt gold type modes. In manual i can fly level at 35mph, fbwa i can hold altitude at 41% throttle and 38mph airspeed.(maybe a level pitch issue?) This roughly 4.3amps on my 4s setup. I can do this all day long.

When I switch to both down and cruise, the throttle jumps around a ton, mostly in the high 40 and 50% ranges, and 8 amps. The is no reason for such large jumps in throttle and all over the place.

I was thinking maybe the pitch excel isn’t quite level, as well as perhaps a bit nose heavy? Throughts?

Loss of yaw control during fast descent

This is a topic to cover @sergbokh’s report of loss of control during fast descents.

Flied several hours, no issues on my setup, except the yaw performance.
After succeeded autotune the yaw control was very, very relaxed, almost unusable.
I found that the ATC_ACCEL_Y_MAX was tuned down to 13000 while wiki says [9000 - very slow, 18000 - slow]
So I just copied my Yaw parameters from Copter3.6 params file and that generally fixed the problem.
But there is still sporadic issue when I descend quickly (ThrO is low) then vehicle losts it’s yaw control and turning left and right to a teens of degrees. I will double check my parameters one time but I don’t understand the root cause at moment.

Wiring 4 motors with 4 ESCs to ArduRover

I have 4 motors with 4 ESCs, its all wired up to PixHawk 4 with ArduRover firmware. It’s connected to an 8CH transmitter. I connected motor 1, 2, 3, 4 and their ESCs and I set motor 1, 3 to steer left and motors 2, 4 to steer right in Servo Output settings. The thing is based on my input from RC, it doesn’t match my input from remote control. I know I’m not setting the right settings in place, but I also I couldn’t find any guide on wiring 4 motors/4 ESCs for skid steering. I tried to combine signal wires of 1,3 into one wire so I only enable 1 and 3 channels as suggested in ArduRover guide, but ESCs started beeping and it didnt work. What I am missing?

Arducopter 4, Cube Black, Range Finder issues

@rustutzman wrote:

Arducopter 4 RC1, Mission Planner 1.3.7236.10299. I’ve wired up my SF11/c to the cube black and can get it working using I2C on the gps2 port. I set RNGFND_TYPE1 to 7 and address 102. That seems to be the only way it works. If I move the settings to any other Range Finder, I’ve tried 2, 3, and 4, I continue to get readings in Mission Planners Status window under sonar. Range Finder 1 is always listed as the only one active and Mission Planner reports range finder x is not found.

I’ve tried using serial 4 on the gps2 port but couldn’t get any readings after double checking the settings on both the sf11/c and the cube’s serial4.

I’m trying to get both the hereflow on can2 and the sf11/c working at the same time.
My question is.why doesn’t this work with other range finder ports. Am I missing some setting somewhere?
