Probably wont be able to listen in , not sure how, but the original point of the topic was how do we get more involved on the hobby FPV side. A lot of fixed wing FPV flyers use something other than Arduplane. When asked, most either don’t know about it, or think it is too difficult to set up. And most of the “too difficult” is coming word of mouth. How can we change that?

Have the minutes been stopped? They’re really good for the community to keep up with the developments and direction of ardupilot - they’re pretty much the only window we have into the inner workings of Ardupilot.

@fnoop minutes come normally in a second email later in the week!

I’ve discussed with Craig and I’ll start to send them out directly.

Just to clarify- so the minutes will no longer be published here?

I’d be interested in the answer too
ArduPilot Dev Call 2018-02-06
Attendee count (max) : 23
Pre-Meeting
UTC2301 - Randy and Copter
New version of Leonard’s loiter
https://github.com/ArduPilot/ardupilot/pull/7659
Incorporates EKF reset changes
Needs testing on this thing!
tridge needs to approve due to quadplane changes
Leonard may already have tested on a quadplane
Need to test it on tailsitters etc
Now passing lean angles rather than -4500/4500 signal
Smoothing gain changes
High number == crisp
Used to have two numbers
Now have single crispness number
ATC_INPUT_TC
Should be more responsive
Will allow us to stop cutting corners in waypoints
Follow / chase
Smarts in drone itself
New PR for this
Distance max
Sysid parameter
If 0 will grab onto first one that it sees
Offset parameters
In other vehicle body frame
Or can be fixed for yaw (NED)
If 0 they will grab offsets from original distance
Type can be relative to heading
Has yaw behaviour
There’s a TODO list on the PR
Amilcar has some extrapolation code he can apply on top of this PR
They use RTK GPSs
Compensate for variable latency
UTC2311 - Randy and Rover
No release in last week
Bunch of people testing
Boat station keeping (see video)
Weather-vaning desired
Current estimation desired
EKF wind estimation?
Some sort of higher-level estimation
Start measuring velocity when we first quiesce because we’re within the waypoint radius
Learn current this way
Continuous update required
Maybe a less-complex approach?
Maybe position-hold-in-autotune approach?
Always point inwards
Push engine up (instead of leaning)
Might require different strategies for different engine types
Servo function for “drop anchor”?
Separate mode, position hold
Fixing pivot turns has come up
Gunning one of the engines is unsubtle
Vectored thrusters?
UTC2324 - tridge and Chibios
Sid’s UAVCAN stuff!
Works well
Tridge has flown on his Ranger
In the pr-chibios branch
Mark’s buzzer support
Play tunes now!
Unmerged as yet
Mark’s soak testing uncovered a locking issue and other important bugs
Still on elusive issue being chased
MdB: I’ve had master chibios + lua running for ~36 hours total (mostly 12 hour increments) without any major issues so far
Revo Mini on Chibios is running
But requires weird hacks
Disable initialisation of GPS UART
Otherwise USB disconnects/reconnects at 1Hz
Mindpx-v2 is getting closer
No buzzer
Logging doesn’t work to SD card
Probably wrong pin definitions
Gyro unhealthy messages
SPI definitions probably wrong
Luca from vrbrain has cleaned up all vrbrain for NuttX build
Vrbrain hwdef.dat file coming!
Should we merge patches that merge vrbrain into px4?
If we’re moving to ChibiOS anyway?
Risk to HAL_PX4
Would need to see the patches before knowing!
Vrbrain should work on master
The maintainer thinks so!
Tridge hasn’t tested, just ensured it wouldn’t negatively impact on other HALs
Add to CI
Francisco will do
Luca to specify
Kevin from Drotek
P4 Pro support on ChibiOS?
Yep, they’re working on it
Px4-v1 still needs to be done
Pretty much a dead platform anyway
USB identifiers are different for each board now
ArduPilot_fmuv4_3E0031000B51353233343932-if00
Usb ids settable in apj tool?
Channel) JW: is there any way to burn the mfg’s serial into this?
[10:38 AM] (Channel) JW(apache405): ex: HX4-06001-7801277
[10:38 AM] (Channel) MdB: Jeff: that would be nice…
[10:38 AM] (Channel) JW: agreed
[10:38 AM] (Channel) MdB: But is that anywhere in the hardware level for us?
[10:38 AM] (Channel) JW: it can be burned at the jig
[10:39 AM] (Channel) MdB: I keep forgetting that bootloaders are being flashed already which means you have the chance to burn that sorta thing
[10:39 AM] (Channel) JW: i think there’s a standard for this actually
[10:39 AM] (Channel) JW: i have to see what ASTM, et al have put out
UTC2340 - singletons and panics
UTC2344 - Revo Mini PR
By Night-ghost over a long period of time
Current PR is getting an awful lot better
Loyal following in Russion and in RCGroups
Light, fast boards with OSDs attached
Kind of a low-level mini-RTOS
Many useful drivers and driver fixes!
Some concerns about maintainership
When some PR breaks it, will he review code to fix it
He is responsive on problems with his code
Tridge has been fixing things up to coding standards and the like
RevoMini does run under ChibiOS
Doesn’t have all the features that the raw port does
Or the usage of it
AP_HAL_Lite?
Stm32lite?
He’s thought about avr, at least
Can we break out integrated OSD support too?
LV: And ys. He redid the old MinimOSD code
LV: translation issues
Tridge is getting an F7 with onboard OSD support
Makefile build
Parameter system
Tridge has been fixing this up
OB: Has anyone been following this? https://www.rcgroups.com/forums/showthread.php?2784349-Ardupilot-on-OpenPilot-Revolution
137 pages
More of discussion on Russian forums
[10:52 AM] (Channel) OB: Looks like that’s where most of the testing is happening
CI?
Binary builds?
E.g. event-based system in HAL
Tridge could do this for all HALs
Add it to CI, see if it breaks stuff?
Completions stuff?
Tridge prefers thread-per-bus
But it works for him….
General support for it going in if tridge is happy
UTC0005 - RadioLink
Peter and tridge have been working with an engineer
Conversations are going really well, they’re starting to open up a lot
UTC0024 - Patrick is a team member
Vote passed!
Congrats PP!
PocketBB / cape coming!
Would like moderator access on forums
UTC0025 - Canberra Unconference
Anyone coming not in Skype group - let tridge know!
Bunch of people arriving early
Will create a google doc for arrival time and contact numbers
27 people
Full room!
Any bigger and we’ll need a larger venue!
CMAC
Small donation from tridge to CMAC
$300 to help cover some costs
BIGLY SWARM
SkyViper only
Just need to do more work on other vehicles
Need to line up speakers some more
MdB will talk on Lua
Recording will happen
Streaming maybe not so much
UTC0033 - swag vote
10 in favour
5 for zazzle
1 none
Called in favour of Jani starting swag shop for AP
So now we need to work out for how long he looks after it
No, we’ll bring up an explicit thing if required
Reports will be made to marketing committee on sales etc
Will be open within 24 hours!
Next week many more items will go in
Blog post coming
UTC0039 - Who are we attracting?
Roadmap?
objectives/goals
Not so much features x/y/z
Come up with one at unconference
Ask major contributors what they foresee what they’re planning on working on
Each dev controls own time
Larger partners like to see plans
Who is our user base?
Identify groups
Find low-hanging-fruit for these groups
E.g. researchers => ROS
E.g. aerial photographers => ???
Conversion strategies?
E.g. howto convert DJI vehicle to AP
Parner on-lining pipeline coming
Don’t count on Unconference solving all problems!
But there will be a discussion at UC for it
Please try to solve new problems with new resources rather than existing resources
Need more emphasis on the CoC
Lots of ideas, not enough directable resources
James will raise his document again at the unconference
Might make it easier to have a consistent message
And starting point for marketing group

I think you rather can read this positively, i.e., that there are indeed folks which read your minutes and appreciate the service you provide

I am not a Dev, but I look forward to the minutes from each call, shortly after reading the agenda for each call. Please keep up the good work!
