Futaba dm-140gink Demo

The Futaba DM-140GINK Demo is an OEM device from Futaba.

The following machines have the DM-140GINK build in: MSI_Media_Live, Hiper HMC-2K53A, FIC Spectra....(please add)


The DM-140GINK includes is a combined device with the following functions:

- a VFD

- a Wireless Network Interface (801.11 B/G usb device Ralink chipset RT2571WF )

- Front Panel Keys

The module is a controlled by a Weltrend WT65F5 USB Micro controller.

Wireless NIC

The DM-140GINK includes a 801.11 B/G usb device Ralink chipset RT2571WF - rt73 driver, 64-bit supported

Other Rt2x00 drivers are also available from RT2x00Wiki.

Google on ndiswrapper if you need more help on installing the driver with ndiswrapper.

Warning.png Warning: The above ndis driver does not work on 64-bit platforms. If one finds a solution for 64-bit, please add it to this page.

Working setup on x64: rt73-cvs-2007100304 from http://rt2x00.serialmonkey.com/rt73-cvs-daily.tar.gz
make and make install
USB subsystem must be up and running

Add "alias wlan* rt73" to modprobe.conf

Edit /etc/network/interfaces

# The wireless network interface
allow-hotplug wlan0
iface wlan0 inet dhcp
pre-up ifconfig wlan0 up
pre-up iwconfig wlan0 essid qwerty
pre-up iwconfig wlan0 channel 11
pre-up iwconfig wlan0 key xxxxxxxxxxxxxxxxxxxxxxxx
pre-up ifconfig wlan0 up

Run ifup wlan0 and you should be up and running!

Note, you can only use channel 1 - 11!

DEMO









The current LCDproc 0.5.2 does not have support for the dm140 in the package.

Henrik Larsson created this rpm with a driver for the dm140. Thanks Henrik, you rock.

Henlar: Here is a LCDproc working with dm140 v0.2 have the dm140_char() fixed. It is not bug free but it works.

Download.png LCDProc 0.5.2 version with Henlar dm140 driver v0.2


Quick howto:

./configure --enable-drivers=dm140
make
make install
edit /usr/local/etc/LCDd.conf
  • Change the driver to dm140
  • Change the driver path from server/drivers to /usr/local/lib/lcdproc
  • Check so the dm140.so file is copied to the directory /usr/local/lib/lcdproc/ also. If not, copy! You will find it in ./server/drivers. Make sure you spelled --enable-drivers with a 's' at the end!


Fire it up with:

 LCDd

or troubleshoot

/usr/local/sbin/LCDd -c /usr/local/sbin/LCDd.conf -d dm140 -r 5

If you want it running in foreground add -f and if you want lots of scrolling text add -r 4. This will show all calls to dm140_functions.


Note

Geeko head48.png openSUSE 10.3 may receive the following error message when fire-up lcdproc.

Driver [dm140] init failed, return code < 0
Module /usr/local/lib/lcdproc/dm140.so could not be loaded
Could not load driver dm140
There is no output driver


You need to create the devices:

mkdir /dev/usb
mknod /dev/usb/hiddev0 c 180 96
mknod /dev/usb/hiddev1 c 180 97
mknod /dev/usb/hiddev2 c 180 98
mknod /dev/usb/hiddev3 c 180 99
mknod /dev/usb/hiddev4 c 180 100
mknod /dev/usb/hiddev5 c 180 101
mknod /dev/usb/hiddev6 c 180 102
mknod /dev/usb/hiddev7 c 180 103
mknod /dev/usb/hiddev8 c 180 104
mknod /dev/usb/hiddev9 c 180 105
mknod /dev/usb/hiddev10 c 180 106
mknod /dev/usb/hiddev11 c 180 107
mknod /dev/usb/hiddev12 c 180 108
mknod /dev/usb/hiddev13 c 180 109
mknod /dev/usb/hiddev14 c 180 110
mknod /dev/usb/hiddev15 c 180 111

I added these lines to /etc/init.d/boot.local

Note: MythDora 4 also errors as openSUSE 10.3 and the same solution works. Instead of adding the lines to /etc/init.d/boot.local you need to add them to /etc/init.d/rc.local - I also add /usr/local/sbin/LCDd to the bottom of rc.local to ensure it is running at startup.


Configure mythfrontend to use the VCD

The mythlcdserver is started automatically when configured in mythfrontend.

You can find the setup options in Utilities/Setup->Setup->Appearance->LCD device display Check the Enable LCD device.

Pluto module source code

The Pluto guys seems to have this device working and deb file is available: http://plutohome.com/support/index.php?section=packageDownload&pkid=619

Since the site above seems unwilling to send the source code I downloaded it off their development-build;

-Media_Live_LCDButtons.src.tar.bz2

The Pluto dev-site will allow you to download additional source-code since there most likely are dependencies to other modules; deb.plutohome.com

Front panel keys

Incomplete.png Incomplete, needs to be expanded. Please help to fill the gaps or discuss the issue on the talk page


Using the keys in mythTV


Information.png Tip: Moosylog : Nov 2007: I don't have the device, but have put some new info on the Talk:Futaba page that needs to be tested. It seems possible but you need to remap the keys to other values. Can you please test this and update this section of the wiki.


Here is a list of the front panel buttons

The 'xev' command gives us the following information about the keys:

Use the keys in Gnome/KDE

In Gnome, there's one place where you can define keyboard shortcuts for various predefined actions (opening the home folder, launching your default web browser) by just pressing the key combination.

If you want to add keyboard shortcuts for other commands, you press Alt-F2 and type gconf-editor to open the Configuration Editor, then navigate to Apps > Metacity. Within Metacity, you define the command in Keybinding Commands and define the keyboard shortcut in Global Keybindings.

The advantage to the Configuration Editor approach is that you can define a keyboard shortcut for just about any command you can think of. The disadvantage is that you have to type out the keyboard shortcut. You can't just press Control-Shift-A. You have to type <Control><Shift>a Free Image Hosting at www.ImageShack.us

KDE also has two places to define keyboard shortcuts, but they're both traditional point-and-click environments.

Keyboard shortcuts for custom commands are defined within the menu editor—so the disadvantage to KDE's approach is that you have to have a menu item (yes—it appears in the menu) for every command you create a shortcut for.

You don't have to type out the shortcut, though—you can just press it—this goes for both the predefined commands and the menu items.





Bluetooth

The Bluetooth module appears to be a standard HCI over USB interface. No special driver is required to operate the device. Tested with Mythbuntu 7.10 and MSI Media Live.

User experience

Moosylog :Started this page for some friends that have the device - helping out

Hans_B :Oct 2007: Hans is currently testing the LCDProc code on 32bit. WiFi working with ndswrapper.

Moosylog : Oct 2007: Installed openSUSE 10.3(32) on a MSI Media Live. (remote, VFD, wireless work) - no solution found for front keys.
