OK ...

I could not stop myself, and played with it today.

Used the tweaked debain build here :
http://www.raspbian.org/PiscesImages

Everything I did on the command line was pretty OK ...
Everything in X seemed pretty slow.

I just realized that the old USB charger I was using for power was very under-powered (600Ma).
I am hoping that could have something to do with the lackluster performance.


But right now it makes a good wireless terminal on my TV :-)

Managed to install and use Synaptic/wicd/Midori and a few others without any problems ...
Even watched some choppy HTML5 video on YouTube.

Cheers

From Barrys blog
RasPi coming soon
I received the paperwork from Element14, dated 29 June, which probably means that my Raspberry Pi was posted also. Tomorrow (Monday) is a public holiday here, so I am expecting the parcel to arrive on Tuesday.

When it does arrive, I will most likely switch over to working intensely on porting Puppy to it.

Good news. I would much rather have a BarryK alpha build than the existing 'maturing' offerings :D

A high priority is for someone with knowledge of C coding -- and it would be helpful to have a bit of GTK coding knowledge too -- and figure out why gtkdialog is rendering the widgets in reverse order.

There is probably some simple thing in the source where it flips the rendering order.

this is what i was pretty much expecting as far as performance goes.
excellent commandline type usage, and or server applications with no X session running.

im planning on setting up games on the rasp using: xinit openarena
type command to run the game without loading all the WM stuff first. And the games being on their own sd card, so the user swaps cards to change games, just like a nintendo DS.

There is something interesting here:

Puppy is a desktop OS.... websurfing, playing youtubes, running gimp..... etc....

However this is the weakness of the Rasp Pi, it isnt suited to run a desktop environment. Puppy is about the last thing you would want to run on the rasp pi, well atleast the Puppy we are familiar with.

This is why im am planning to create a command line driven OS for the Rasp, with games running without the WM stuff, and if you select a application that needs a WM then and only then it would be loaded, and and when you exit the application, the WM exists too..

i think it is doable with a propperly setup text menu system.

the idea to prepare RPi to run games without X is good - if u achieve the same like with quake it will be nice cheap game machine

btw. i've heard that RPi creators are working on driver to use GPU for X, now everything for X is doing only CPU, i hope when they release drivers RPi will be much better as desktop

I've been having a go at getting some sound out of the Pi (reading the article in MagPi).

I've tried the modprobe snd_bcm2835
Nothing.
Any ideas?

the instructions for sound are for Debian (editors of MagPi are using this distro), maybe this not work for Arch

i found some info there:
http://www.raspberrypi.org/phpBB3/viewt ... =28&t=6673

and for RPi as a game console:

@antiloquax

Are you talking about no sound with HDMI or via audio jack?

Just tested here (with Arch), sound via HDMI works for me, audio jack not. Maybe it must be preselected like HDMI vs. video out? Just a guess.

If we are talking about HDMI, I used modprobe snd_bmc2835 and installed deadbeef (includes a alsa-lib) and mplayer. Without mplayer or at least a dependency of it, deadbeef doesn't support mp3.

This from the Puppi Arch wiki
Step 12 Add Multimedia capability
sudo modprobe snd_bcm2835 at prompt after login / before "startx" for sound
pacman -S deadbeef
http://puppylinux.org/wikka/PuppiArch

The most I have tested for is a tone.
Calling in an improving broadcom graphic chip driver will give us increasing oomph [a technical term] :)

If anyone is able to afford two Raspberry Pi's
and can send one to our skint (impoverished)
darkcity who lives in the North of England that would be great . . .
Darkcity is doing a lot of documentation for the wiki.
Be great if he could be sent a board or we had more Rpi documenters for the wiki. Contact him directly.
I already gave my second Rpi board to friend 'Shadow'.

Here Lord and Lady Upton of Cambridge (you heard it here first - MBE and knighthoods etc come first) dish out a board to a young American genius geek.

I have offered my "spare" RPi to someone else. If he doesn't get back to me today, I'll let darkcity have it.

I've also had some in this lifetime ;)
I learned to meditate when I was a student. Sort of a lapsed Buddhist!

I have sound.

Code: Select all

pacman -S alsa-utils alsa-oss alsa-plugins
gpasswd -a root audio
speaker-test -c 2
... and I was blasted with white noise!
I've compiled schismtracker (as recommended in MagPi)
and downloaded some modules.
Added snd-bcm2835 to my rc.conf.

I went and bought a breadboard and some LEDs yesterday. But I forgot to take the magazine with me. I'll have to go back for some resistors etc. Maplins has what you need!

Actung Lobster off topic interlude
I've also had some in this lifetime.

I am pretty much a heretic Buddhist (not really possible)
So do not accept the fantasy of rein carnation. I was not a wombat in a previous lifetime. In this one I definitely am. What I am in other multi-verses probably defies imagination . . .
So I interpret our past being as past lives and the actions (karma) that we set in motion effects our future being or life . . .
Any adult talking of Purelands, Father Christmas, Heaven, Hell or other fairy tales is Lady Gaga (at least partly) in my experience, no matter how enlightened, venerated or medicated.

I practice Buddhism because it works for me. You probably had reasonable results with meditation?
Here is my particular heresy . . .

I will be using the Rpi as a shrine computer eventually

question from someone who has no clue (me):
can all/some of the scripts that have been written for arduino be somehow used on raspberry? I mean the ones that have only to use a lesser amount of pins.
or perhaps arduino can be joined to raspberry and programmed in conjunction. like I said I don't know anything just exploring possiblities.

Sorry, I don't know either. Although, I have heard Eben talking about linking up Arduino and RPi - that does work.

here is the arduino code and instructions for blinking your first LED
http://arduino.cc/en/Tutorial/Blink
don't know if it any use to you.
to get the arduino gui to work on puppy it needs java installed, so far I have not been able to determine if there is a java compatible with both puppy and arm together.

Thanks aarf! I'll check it out.

EDIT
I'm sorry I won't be able to help darkcity out - I'd already offered my spare Pi to Jaseman (of the MagPi magazine), and he's confirmed he does want it.

EDIT (again)
Thought I'd post a couple of pics of my Pi setup (this actually isn't in my room - it's just where I can get hooked up to ethernet!).

Here's my first proper assembly program (I wrote this myself, rather than copying from websites!)
It finds the Greatest Common Divisor of 6099 and 2166. See Knuth, The Art of Computer Programming (3rd ed.) page 4.

Code: Select all

 .section    .data

string:
    .asciz "Euclid's Algorithm: Greatest Common Divisor\n"
len = . - string
result:
    .asciz "Result: %d\n"
m:
    .long   6099
n:
    .long   2166

.text
    .globl  main

main:
    mov r0, $1
    ldr r1, =string
    ldr r2, =len
    mov r7, $4
    swi $0

    ldr r5, =m
    ldr r2, [r5], $4

    ldr r5, =n
    ldr r3, [r5], $4

loop:
    sub r4, r2, r3
    cmp r4, r3
    movge   r2, r4
    bge     loop

    cmp r4, $0
    movgt r2, r3
    movgt r3, r4
    bgt     loop

    mov   r1, r3
    ldr r0, =result
    bl printf
    mov r7, $1
    swi 0

I've had some help from someone on the RPi forum. Still lots to learn ...
