Just released FlightPlot version 0.2.19, added "export as image" feature.
Mark Whitehorn
@kd0aij
That's good; I'll have to look more closely at the code... The FIFO is interesting, I hadn't even noticed it existed, since in MatrixPilot I was setting the sample rate to 200Hz and using the data_ready interrupt as a clock.
Anton Babushkin
@DrTon
200Hz is too low IMO, you will loose a lot of data. need to use as much as possible to avoid aliasing and reduce noise.

@kd0aij
Recent builds of FlightPlot are very slow on Ubuntu 15.04. Version 2.14 is OK
Mark Whitehorn
@kd0aij
Never mind, v.0.2.19 is running fine today. Interesting that 2.14 was running OK when 2.19 wasn't though.

just upgraded to Ubuntu 15.10 and ran into a bug which hangs the GUI. Is anyone else using 15.10?

I'm having trouble loading a log. Using FlightLog 0.2.21 I open 120.BIN, but I can't plot any data. Log Info reports a length of 0, but 3.8M updates. It opens fine on Mission Planner. Is there a limit in size? The file size is 125MB. Thanks for a great tool!

@kd0aij
how are multi-instance IDs supposed to work? Are all instances of a multi-instance topic plotted automatically?
Andreas Daniel Antener
@AndreasAntener
which one do you refer to? they need to be logged into different messages, e.g. OUT0 - OUT1
Mark Whitehorn
@kd0aij

This is the auto-generated ULOG format spec for the accel sensor message:

const char *__orb_sensor_accel_fields = "SENSOR_ACCEL:uint64_t integral_dt;uint64_t error_count;float x;float y;float z;float x_integral;float y_integral;float z_integral;float temperature;float range_m_s2;float scaling;uint32_t device_id;int16_t x_raw;int16_t y_raw;int16_t z_raw;int16_t temperature_raw;";

The multi-instance ID is in the header of the log message. It is not indicated by the msgID or the "name" of the message. Instead, the multi_id field in struct message_data_header_s specifies the instance number along with a bit labeled "active" in the FlightPlot code. This field was hardwired to 0x80 in logger.cpp, with comment "Non multi, active".

@kd0aij
@AndreasAntener I see I forgot to mention that I was looking at the "new" ulog format, and not sdlog2
this is the context: https://github.com/PX4/Firmware/pull/4117#issuecomment-204064709

@AndreasAntener
ah :) I haven't looked at this yet

Does FlightPlot not support the latest Copter v3.3.x logs?
Mark Whitehorn
@kd0aij
I didn't think APM logs were ever compatible with FlightPlot. When was that working for you?
kalnir
@kalnir
Yes, the earlier logs used to open correctly
Mark Whitehorn
@kd0aij
you're right. I just never tried it.

@thedevleon
Got a question - I want to open a log generated by a Pixhawk running a 4 day old master of PX4 - but when I open it in the latest FlightPlot I get:

@ripfree
I have a more basic question. I've downloaded the jar file for Flightplot, but once unzipped, there isn't even one executable file anywhere. How do you run the program??

@ripfree Instructions here: https://github.com/DrTon/FlightPlot

@kd0aij
@huanglilong @zubair123khan You'll have to be more specific if you want help. v0.2.24 opens and display px4log files properly for me on Ubuntu 15.10
I'm using the OpenJDK Java 7 runtime

I downloaded the binary for Mac OS X and tried to load some PixHawk .bin logs. I keep getting Java errors. I am running Java (Version 8 Update 91). The errors I get are https://files.gitter.im/DrTon/FlightPlot/2knD/Screen-Shot-2016-07-04-at-5.48.06-AM.png and https://files.gitter.im/DrTon/FlightPlot/Bnas/Screen-Shot-2016-07-04-at-6.06.07-AM.png. Any ideas on what I might have setup incorrectly?

Hi, a short question, does FlightPlot support the new logger files *.ulg already? - I saw some implementation on jMAVlib...
Eike
@ecmnet
but it seems not to work with the latest *.ulg files
Mark Whitehorn
@kd0aij
try the PX4 forks of FlightPlot and jMAVlib: https://github.com/PX4/FlightPlot
Eike
@ecmnet
@kd0aij Both seem not to be up to date though...
Mark Whitehorn
@kd0aij
they are working for me on a branch based on commit bc6e83f5e3a from 2 July
Mark Whitehorn
@kd0aij
@ecmnet Just tested latest master, and ulog file is OK in FlightPlot v0.2.22 from PX4/FlightPlot (branch ulog_format) Maybe you were trying to use master? ulog_format is actually a pending PR against DrTon/FlightPlot
Eike
@ecmnet
You are right, I was trying master. Thank you.

Hi, guys...
I'm using ROS Indigo to run up my coding and I use Pixhawk as my flight control board and my ground station is QGroundControl which runs on Ubuntu 14.04.
And I'm using Rviz to launch my path planning and 3D-Mapping with Asus Xtion Pro LIVE, but I have no idea is that possible for me to plan and execute for my drone to move to the right way in the real world?

@dblitza
Hi, so when I run the Mavros Offboard Example, it keeps printing out "Offboard enabled" but it never arms the drone and prints out "Vehicle Armed"
Thus not allowing me to fly the drone

@Gabriel-ftero
Does flightPlot run on Windows? If yes, where do I find a proper installation instruction?
