@ikenshini

I would read this: https://wiki.paparazziuav.org/wiki/Overview

averroken

@averroken

ah, that is another thing

ikenshini

@ikenshini

yes - but it works with the AR Drone, it is used for autonomous flights - much easier than programming a drone without it

but if you're doing something simple, AT commands can be used

averroken

@averroken

what i'm trying to do is control a ar drone with a kinect v1.

but i didn't understand how the at commands works, thats more the problem.

Has anybody had this error when installing the gcc-arm-embedded repository?

Errors were encountered while processing:
/var/cache/apt/archives/libstdc++6-armhf-cross_4.8.4-2ubuntu1~14.04.1cross0.11.1_all.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

Felix Ruess

@flixr

@dgberry1 that seems to be a bug in ubuntu packaging: https://bugs.launchpad.net/ubuntu/+source/gcc-4.8-armhf-cross/+bug/1557205

Dan Berry

@dgberry1

@flixr Okay I'm checking it out. I found other having this issue too.

https://bugs.launchpad.net/ubuntu/+source/gcc-4.8-armhf-cross/+bug/1557205

does the 4.9 version work with paparazzi?

Felix Ruess

@flixr

yes, we also ran into this bug in our travis builds, that's why I disabled them for now (as they always error because of this)

4.9 should work... but I haven't tested it...

Dan Berry

@dgberry1

okay thanks.

I might give it a try. I did find a note about Nvidia video being the culprit.

Dan Berry

@dgberry1

I found this command to get the cross compiler to install.

sudo apt-get -o Dpkg::Options::="--force-overwrite" install -f

It worked and I was able to move forward with the installation

rambalakrishnan

@rambalakrishnan

the wiki says that 0.017s is the minimum period for telemetry messages. is that also true of ground-to-aircraft messages? i would like to set a joystick update frequency in excess of 60Hz

Gautier Hattenberger

@gautierhattenberger

@rambalakrishnan you should be able to increase the update rate of the joystick by changing the period parameter in your joystick file. The smallest theoretical period is 1ms, but it is probably way to much for the telemetry. 60Hz should be fine if you don't have too much downlink telemetry or enough bandwidth.

averroken

@averroken

thanks for the information, problem solved

Felix Ruess

@flixr

if anyone has a launchpad account, maybe also mark bug https://bugs.launchpad.net/ubuntu/+source/gcc-4.8-armhf-cross/+bug/1557205 as "this bug affectes me"... maybe they will fix it faster then...

ah, at least a fix is now proposed...

Beta release 0.2.1 of the Flying Robot Command available for public consumption: https://github.com/paparazzi/flyingrobotcommander

Gautier Hattenberger

@gautierhattenberger

nice work ! (and nice picture ;) )

Felix Ruess

@flixr

ah, the ubuntu packaging bug in armhf-cross has been fixed :-)

Dan Berry

@dgberry1

@flixr that is good.

I've downloaded and installed the DFU-Util and I am having trouble flashing my Elle0.

@flixr

you might want to try with a newer dfu-util version

what distro/version are you using?

Dan Berry

@dgberry1

Run version: v5.9_devel-359-g63a7b79
Build version: v5.9_devel-359-g63a7b79

Felix Ruess

@flixr

I mean your linux distro

Dan Berry

@dgberry1

Ubuntu 14.04

dfu-util is version 0.5

Felix Ruess

@flixr

then you can use dfu-util from my ppa (I backported 0.8 to 14.04): https://launchpad.net/~flixr/+archive/ubuntu/backports

Dan Berry

@dgberry1

my dfu-util is version 0.9

it is still not uploading

using lsusb, I can see the device.

Bus 003 Device 005: ID 0483:df11 STMicroelectronics STM Device in DFU Mode

Felix Ruess

@flixr

dfu-util: Cannot open DFU device 0483:df11

do you have access rights to it?

Dan Berry

@dgberry1

I forgot how to check

I was going to try a different USB cable too

Felix Ruess

@flixr

ls -l /dev/yourdevice

dmesg | tail should show the shorter path to the device from when you connected it
