Re: [pygame] Multiple keyboard
This look like something we need, but for Linux. Is this available (I haven't find anything like it on Google) Thanks P. On 11-11-19 11:32 PM, Alec Bennett wrote: Have you tried the pyHooks module? It can hook the keyboard at what might be a lower level than pygame. I know, for example, that it works whether or not the application has focus. There's a demo script that prints all the info about a given keystroke, maybe there's something in it that differentiates multiple keyboards. Apologies if this was already mentioned.

I tried pressing 1 then 2 on one keyboard and found the serial number doesn't change. Interesting. Unfortunately when you input from another keyboard the serial number just seems to increment. With just 2 keyboards I guess this should be a matter of _even_ serial numbers being from one keyboard, and _odd_ serial numbers being from the other keyboard. I'm not sure how you detect the serial numbers from python though. Perhaps someone else here knows more about this stuff.

The latest, Puppy4.3.1, is the prettiest and easiest to use so far. The standard distro is tiny -- 100MB in size, and comes with a lot of stuff built-in, but not python as far as I remember. If you install the devx file for Puppy4.3.1 you get python and all the development sources, headers, etc to compile against. Installing pygame should be simple. It is a long while since I did that though. Puppy will boot straight from live CD, loading entirely into RAM and releasing your CD drive for other uses. Or you can run it from USB drive. It has some drive-saving features, like caching writes so as not to shorten the flash drive's life unnecessarily. Or you can install it on a hard drive and run it like any standard OS (what I usually do). Puppy is very fast, with a very small footprint, but I also use it on one of my machines for running 3D modelling stuff like Blender, sound editing, etc. It is also the only live Linux distro that I know of that is able to play almost any multimedia immediately. Puppy has some drawbacks, mainly resulting from cutting back on extra things not often used. Also, in an attempt to be as user-friendly as possible the user logs in as root. This scares a lot of die-hard Linux users as a possible security problem, but in practice it is fairly safe, and it isn't hard set up the default login as a less priveleged user. The main site: http://www.puppylinux.com/ The most active forum: http://www.murga-linux.com/puppy/ Ibiblio, where the distros and packages are: ftp://ibiblio.org/pub/linux/distributions/puppylinux/ but you'll want: ftp://ibiblio.org/pub/linux/distributions/puppylinux/puppy-4.3.1/ and the packages (pet files): ftp://ibiblio.org/pub/linux/distributions/puppylinux/pet_packages-4/ You can create your own version of Puppy with python and pygame already in there using woof (I'm not kidding, it really is called that). If you want to create a Puppy specifically for the ARM processor, woof might do that too. I can't help there as I haven't used woof, but there are a lot of people in the Puppy forum who I'm sure would be delighted to help.

Thanks Pierre sounds like a fun project! from my understanding of non-cutting-edge cmos sensors, they give out 8-16bit per pixel of range? Then for color they use a bayer filter, to filter out the various wave lengths of light... usually RGB filters. Of course if you took 1/3rd the resolution of that image, then it could be 16/16/16 per pixel I guess. In the same sense you could work with a pygame Surface - but think of the colors in a different resolution. Double the resolution, and you've doubled the color depth. But you might want to check out exr... http://www.openexr.com/ and it's python bindings... http://excamera.com/sphinx/articles-openexr.html ... thinking of it a bit more... you should be able to display higher depths via opengl. With pygame and opengl you should be able to set a higher bit depth... if your driver supports it. see: http://pygame.org/docs/ref/display.html#pygame.display.gl_set_attribute Then send your data to the relevant bit depth gl texture, and you should be able to display whatever your driver supports cu. Hi all, they give out 8-16bit per pixel of range? René, you put the fingers exactly in the center of our question: Why camera gave 12, or even 14 bits per color, if Windows, Display, Grahic cards are limited to 8 bits per color ? HDMI 1.3 is 1 year old only, Windows will support this (correctly ???) in 1 month. Only specialized software are supporting this. But who has PhotoShop at home ? Ok, some print pictures, but in my opinion, there are even less dynamic range on paper than on LCD (this need to be confirm). About Bayer, some sensor work differently, if you are interrested, look at Foveon sensor (bought by Sigma), and this patent: http://www.google.com/patents/about?id=_mzIEBAJdq=Yves+Audet That's my boss's patent, the CMOS sensor I'm working on And yes it's a fun projet, mixing Pygame with chips design :-D Pierre

The Foveon sensor is of course different. Even if the display is not capable of showing 10 bits per color, it makes sense to capture at it to allow for post processing. You could mess with the levels or extend contrast without running into banding or aliasing or having to dither.

But I need first to create RGB101010 software to see if DeepColor makes sense or not, before optimizing CMOS chips. Since I like Python and I have Pygame experiences, I wanted to do that software with Pygames. Thanks Pierre sounds like a fun project! from my understanding of non-cutting-edge cmos sensors, they give out 8-16bit per pixel of range? Then for color they use a bayer filter, to filter out the various wave lengths of light... usually RGB filters. Of course if you took 1/3rd the resolution of that image, then it could be 16/16/16 per pixel I guess. In the same sense you could work with a pygame Surface - but think of the colors in a different resolution. Double the resolution, and you've doubled the color depth. But you might want to check out exr... http://www.openexr.com/ and it's python bindings... http://excamera.com/sphinx/articles-openexr.html ... thinking of it a bit more... you should be able to display higher depths via opengl. With pygame and opengl you should be able to set a higher bit depth... if your driver supports it. see: http://pygame.org/docs/ref/display.html#pygame.display.gl_set_attribute Then send your data to the relevant bit depth gl texture, and you should be able to display whatever your driver supports cu. Hi all, they give out 8-16bit per pixel of range? René, you put the fingers exactly in the center of our question: Why camera gave 12, or even 14 bits per color, if Windows, Display, Grahic cards are limited to 8 bits per color ? HDMI 1.3 is 1 year old only, Windows will support this (correctly ???) in 1 month. Only specialized software are supporting this. But who has PhotoShop at home ? Ok, some print pictures, but in my opinion, there are even less dynamic range on paper than on LCD (this need to be confirm). About Bayer, some sensor work differently, if you are interrested, look at Foveon sensor (bought by Sigma), and this patent: http://www.google.com/patents/about?id=_mzIEBAJdq=Yves+Audet That's my boss's patent, the CMOS sensor I'm working on And yes it's a fun projet, mixing Pygame with chips design :-D Pierre Hi Sorry I was not clear. Most camera now have RAW mode with more than 8 bits per color (in Bayer color space). Some hi-end camera (like Nikon) capture images with 14bits per pixel Why is this, when current display are limited to 8 bits per color ? It's interresting to see all these answers from Pygame users. I'm really happy to see there a lot of knowledge people in this mailing list. Thanks Pierre
[pygame] 10 bits per color
Hi Is Pygame supports 10 bits per color (ex RGB101010) ? Windows 7 is going to support it Thanks! Pierre

To install sdl dev, run synaptic, and do a search for sdl, it might be

Re: [pygame] Numeric wireless keyboard
Hi
I think you probably can't get those messages without creating a
window, so try creating a window before getting events.
You were right all the way, it works now.
Thanks, I'm ready to verify my ARM platform

Also, you don't want to have a separate poll and wait func, which are
both called and both check for different messages. Both those functions
remove messages from the queue, so if a your poll function gets a
SDL_KEYDOWN message, it would end up throwing out the message and then
your wait function would never receive it. Just do the Poll thing, and
make it's switch statement do the prints for SDL_KEYDOWN as well.
Anyways, once your test program works for your normal keyboard, then you
can try it out with the wireless in order to learn how SDL is or is not
reading that things key data, which will help you understand where the
problem lies and how to solve it.

on Debian (kernel 2.4). So far, we managed to make
application works on
both platforms.
But now we're trying final setup, using a Logitech wireless
numeric
keyboard (pruduct number : 920-000217).

The Pygame application works this wireless keyboard on Ubuntu
7.10.
The Pygame application doesn't work with this wireless keyboard on
embedded ARM platform.
But, keyboard works fine on embedded ARM platform, in a text
editor, or
at command line. So the custom Linux distro detect the USB
dongle and
keyboard works fine. But only Pygame application on embedded ARM
doesn't work with this keyboard.
Do you have any suggestion to help me debug this problem ?
Thanks
Pierre
Hi
This is event received on Pygame apps, runing on our embedded ARM
plateform, when pressing key 1 to 9 on the wireless keyboard :
Event(2-KeyDown {'key': 300, 'unicode': u'', 'mod': 0})
Event(3-KeyUp {'key': 300, 'mod': 0})
Event(2-KeyDown {'key': 300, 'unicode': u'', 'mod': 0})
Event(3-KeyUp {'key': 300, 'mod': 0})
Event(2-KeyDown {'key': 300, 'unicode': u'', 'mod': 0})
Event(3-KeyUp {'key': 300, 'mod': 0})
Event(2-KeyDown {'key': 300, 'unicode': u'', 'mod': 0})
Event(3-KeyUp {'key': 300, 'mod': 0})
Event(2-KeyDown {'key': 300, 'unicode': u'', 'mod': 0})
Event(3-KeyUp {'key': 300, 'mod': 0})

Event(3-KeyUp {'key': 300, 'mod': 0})
Event(2-KeyDown {'key': 300, 'unicode': u'', 'mod': 0})
Event(3-KeyUp {'key': 300, 'mod': 0})
Event(2-KeyDown {'key': 300, 'unicode': u'', 'mod': 0})
Event(3-KeyUp {'key': 300, 'mod': 0})
Event(2-KeyDown {'key': 300, 'unicode': u'', 'mod': 0})
Event(3-KeyUp {'key': 300, 'mod': 0})
Any idea on whats happening ?
Thanks

Hi
Thanks for your support.
How can I get in touch with these guys ?
Thanks

They're on the list, if they get a chance to reply they will. I'm not
sure if it's a Pygame error or SDL or what. Do you know what device
your keyboard is mounting to? Try using lsusb on your dev platform and
again on your ARM platform, and see if they're mounting to different
locations. Then you might be able to force it to mount to the same
location on the ARM platform as it does on your dev platform, and then
perhaps the event parsing will be correct. You should not be getting
identical events for different keypresses though.

Sorry, no idea. You could perhaps dig into the event processing
part of
Pygame but the hardware interface may be on the C/SDL side rather than
Python. I'm sure Rene or Lenard or someone more knowledgeable can
help.

If it's working in a text editor then Linux has the drivers

every
event:
while 1:
for event in pygame.event.get():
print event
If pygame is not getting the event then you probably will
need to look
into mapping the device (from /dev/kb1 or whatever) so
Pygame reads it
for event input.

[pygame] Numeric keypad
Hi I'm trying to get value from numeric keypad, but K_0 ... K_9 doesn't work. Numeric value on alpha keybord works. Can I use numeric keypad ? ex: if event.type == KEYDOWN and event.key == K_0 : DoSomething() Thanks -- Pierre Lafrance --
[pygame] Double buffer question
Hi How can we explicitly use double buffer in an application using pygame ? How can we release the double buffer when quiting application ? Any example I can look at ? We have a problem with that in our application and just don't know whats happening Thanks -- Pierre Lafrance --
Re: [pygame] Double buffer question
Hi When application quit, display stay with last displayed image. Linux is running fine (SSH works fine, we can reboot embedded computer) but display is kind of freeze. We use function pygame.display.flip() when image need to be updated. We dont use any flags for set_mode. We tried couples, but generates errors.

Re: [pygame] Double buffer question
Hi I'm using Pygames version 1.8.1. release. Before debug PG source code, I would suggest you wait I debug mine ;-) I'm farm from being the best programmer... How do I delete the screen object ? Any code example ? Thanks, Pierre Tyler Laing wrote: Well, the flags that work would be dependent on your what your hardware supports. It sounds like you are not deleting the screen object before exiting the program. If I have the time, I'll take a look at the code later and see if I can identify the problem. What version of pygame are you using? -Tyler On Sat, Jun 13, 2009 at 12:23 PM, pierrelafran...@sympatico.ca mailto:pierrelafran...@sympatico.ca pierrelafran...@sympatico.ca mailto:pierrelafran...@sympatico.ca wrote: Hi When application quit, display stay with last displayed image.
