Tux Droid

Introduction

_The_ gadget any linux geek should have ;-)

Moreover it is designed in Belgium, tadaam!

Having kids can help justifying such a, hum, impulsive buy ;-)

Audio

• Plugging everything for the first time, and I got immediately a new Alsa device:

cat /proc/asound/cards
...
2 [default        ]: USB-Audio - TUX RF DONGLE 
                     C2ME BELGIUM TUX RF DONGLE  at usb-0000:00:1d.2-1, full speed

And I can already place an Ekiga test call :-)
Note that echo between internal speaker and microphone is very important so echo tests are quite terrible!
Using the OSS emulation, I can play whatever I want:

mpg321 -o oss -a /dev/dsp2 /path/to/some/mp3
mplayer -ao oss:/dev/dsp2 http://www.paul.sladen.org/pronunciation/torvalds-says-linux.mp3

Reflashing

Then I learn that to run the new (alpha2) tuxdaemon I'll also need to flash the stuffed pinguin.
Instructions are given on the web site and are not... straightforward.

Additional notes:

• Be sure to have installed properly libusb and to have mounted /proc/bus/usb, cf /usr/share/doc/libusb-0.1-4
  • For users to have the right to access usbfs, change /etc/udev/rules.d/020_permissions.rules and add GROUP=usb:

SUBSYSTEM=="usb_device",        MODE="0664", GROUP="usb"

• Recompile dfu-programmer from sources! I first tried alien on the rpm but there were glibc problems and when trying tuxup fuxusb.hex I got the following "common problem" but here it's really not because of permission problems.

Programming fuxusb.hex in USB CPU
Tux not found on USB

• They explain about tuxup fuxrf.hex and tuxup --main . but I had also to fix the tux rf counterpart: tuxup tuxrf.hex
• At the end, replug the dongle and restart the tux

Remote Control

(from the forum)
Press 'ALT' then 'Tux and phone' and you're in test mode.
The arrows should move tux, if you press a digit key, you change the number of movements. So 4 then up will move the eyes 4 times (2 blinks: close - open -close - open)
Read firmware/tuxcore/trunk/standalone.c l262 to see all possiblities

Raw commands

gtdi allows to send raw commands, see /firmware/tuxdefs/commands.h

Misc Tips

• First time, don't forget to plug Tux to the power adaptor for a while (~5h)
• Want to get Acapela Telecom? It's actually available as the tts-daemon

Misc Problems

• tuxdaemon from svn eats all CPU when running daemonised :-(
• tuxttsdaemon launched by gtdi eated 100% cpu after a while with tux off
• gtdi source to be modified: add a space between gnome-terminal -e and "the_commands"
• wrong comments in commands.h 0x1A & 0x1B control both leds

Misc Questions

• How to use alsa natively, not through /dev/dsp2 OSS layer?
• How to control the volume by software?
