Hi vali!
Vielen Dank für den guten Hinweis! Die Klasse in den globalen Kontext zu stellen und per autostart mit dem session-Objekt zu füttern hat das Problem gelöst.

Hallo zusammen!
Ich hatte jüngst ein interessantes Telefonat mit einem Dreambox-Entwickler. Er meinte sinngemäß, zur Entwicklung von Plugins sollten zwecks Stabilität keine Python-Threads benutzt werden. Deswegen schreibe ich nun alle meine Plugins so um, dass sie mit Timern und Callback-Funktionen laufen. Dabei stelle ich aber ein Problem fest:
Wenn das Plugin mit SESSIONSTART gestartet wird, arbeitet der Timer nach ein paar Sekunden nicht mehr. Er wird offensichtlich während des Bootvorganges bereits gekillt. Wenn ich den selben Code z. B. mit EXTENSIONSMENU über ein Menü aufrufe, läuft der Timer einwandfrei.Wie kann ich das umgehen (ohne Threads wohlgemerkt)? Oder gibt es andere Techniken?
Hier ein bisschen Quellcode:
Python

Any hints? I think you all can browse those messages, so how do you do that?

Hi all!
I try to build a package with a c program that uses libusb by including <usb.h>. Although I added the DEPENDS line and in my bb file and the option -l usb to the compiler call (see below), the compilation failes with "error: usb.h: No such file or directory".
Some hints:
- I can imagine when I built the package at the first time, the dependencies of libusb have been parsed successfully.
- Compiling that program on my Ubuntu machine works perfectly.Any suggestions from the professionals?
Here is my bb-file:
Code

There is an additional entry ${CFLAGS} ${LDFLAGS}. I changed the corresponding line and now it looks like this:
Code${CC} ${CFLAGS} ${LDFLAGS} vitalwerterfassung.c -o vitalwerterfassung.outThe error that is produced now looks a little different, but seems to point to the same problem as certain libusb-specific functions can not be found:

Okay, it´s time for the next step:
I have to use the generic driver now by calling "modprobe usbserial vendor=0x0E6A product=0x0101". But this produces an error ("Unknown symbol in module (-1): No such file or directory" and dmesg: "usbserial: Unknown parameter 'vendor'") because this specific call needs a kernel compiled with the option "CONFIG_USB_SERIAL_GENERIC=y".
These were my steps now:
1. As I mentioned before, I added both lines in /openembedded/packages/linux/linux-dm800/dm800_defconfig
2. I compiled the image with bitbake
3. I flashed the new image on the DM800
4. I installed your package (thanks a lot!)
5. I tried "modprobe usbserial vendor=0x0E6A product=0x0101", but the generic driver still doesn´t seem to be loaded (dmesg: "usbserial: Unknown parameter 'vendor').
What could have gone wrong? How can I check whether the new kernel options has been set or not? Thanks in advance!

Thank you! That did it!

Hi Satman!
Thanks for that quick answer!
I copied the file to /tmp (as described in http://dream.reichholf.net/wik…einstallation_eines_Paket).

Hi all!
Adding those lines in the dm800_defconfig has no effect on the running modules (listed by lsmod).
Maybe the openembedded-toolchain also somehow needs the module object file?
If so, where should I get that file and where shall I put it in order to create a working image?
In other communitys I found out that this could be possible:
insmod /lib/modules/2.6.9/kernel/drivers/usb/serial/usbserial.ko
But in the dm800, there are only these drivers:
Coderoot@dm800:/lib/modules/2.6.12-5.1-brcmstb-dm800/kernel/drivers/usb# ls -l drwxr-xr-x 2 root root 0 Jan 1 1970 input drwxr-xr-x 2 root root 0 Jan 1 1970 mon drwxr-xr-x 2 root root 0 Jan 1 1970 storage -
There are various versions of a Python skript named evdev.py (have a try at google), which do that job. But you have to comment out some lines that do ioctl calls which otherwise would generate IOErrors (22, invalid argument).
These lines are affected:
Codedef readMetadata(self): [...] self.name = ioctl(self.fd, EVIOCGNAME_512, buffer) [...] values = struct.unpack("iiiii", ioctl(self.fd, EVIOCGABS_512 + number, buffer))The version I am using is attached. If someone of you out there has an idea why these IO exceptions occur...

Hi all!
I want to code a small plugin that does some usage statistics of the remote control or remote keyboard. Does anyone have an idea how all the key-events can be catched in Python? I found out that the /proc/bus/input/devices may be a way, but I would rather use Python... because of lack of C/Linux knowledge...
Best regards!

I am not quite sure, but after intensively exercizing the bitbaker-, openembedded-, opendreambox- toolchain and its directorys, I guess the file is lokated here:
/openembedded/packages/linux/linux-dm800/dm800_defconfig
I will try to edit this file and build a new image. Let´s see if this was a bull´s eye...

Hi all!
I want to add some lines to the boot configuration in order to add USB serial adapter support to the dreambox 800:
CONFIG_USB_SERIAL=m
CONFIG_USB_SERIAL_GENERIC=yBut I have no idea in which file I have to put these lines!
Some information about the environment: I already have bitbaker, git and all that stuff installed. But I am not a linux professional...

That´s it! Thank you for that quick fix!

Hi all!
I want to append a third button the messagebox class. I cloned the original Messagebox class and added some additional code (see below), but the buttons are not displayed when the messagebox is shown. Buttons of Messageboxes with usual types like TYPE_YESNO are displayed correctly.
Here is my class:
