r00x

Same here; noticeable latency of perhaps a few hundred milliseconds when using pixel doubling. Making it kinda hard to click stuff!

r00x

It didn't seem to work... thanks very much for finding that info though! I've confirmed that, if I use rpirtscts to enable flow control, it is indeed enabled and obeyed by the Pi. However I can't get this to work on boot still. So following your findings I tried the likes of "115200r" and also "1152...

Hi there, I've spent a few hours searching for answers but my Google-Fu is terrible, it seems (or perhaps this isn't possible)... I have a Pi Model B on which I want to set the Pi's UART to 115,200 baud and enable RTS/CTS by default. I'd like this to be effective on boot. This is so I can see the co...

r00x

Hi! I can't get motion to run. It's killing me. I've looked at numerous guides online, they all more or less follow the same steps. I'm at the stage I should be able to run motion and connect to it via web browser. When run from command line (motion -n) it bombs out with a segfault (last few lines o...

Well jamesmd95, it's not like you didn't contribute significantly to the thread, is it? And technically on topic... So with my complete lack of moderator powers, I declare this acceptable :lol: would even enter myself if I actually used Facebook, haha. Not to swerve off topic too much, but all this ...

r00x

My net speed is terrible (~3-4Mbps/0.8-1Mbps Down/Up respectively) but two players will still get a smooth experience. Reduce any activity which causes data transfer for smoother play, for instance: - Reduce server viewing distance (less terrain data transferred when moving around) - Reduce number o...

r00x

still finding too much lag. most things are working well terrain generates quickly the only pain is when mining, chopping trees etc the blocks dont always disapear and have to mine them 3-4 times to eventually they do. Its at max overclock too. So going to try it on Bukkit with NoSpawnChunks add on...

r00x

Thanks for the tip, I'll have a poke at that! :) If I'm not mistaken, ~2880 bits should take less than a millisecond @ 8MHz, assuming the transfer is smooth and steady from start to finish. (2880/8000000 = 0.00036 seconds). So I could init the display with 8bits per transfer and synced GPIO before s...

r00x

Yes I should imagine it would be more convenient to use larger transfers! This may work well for putting content on the display, where it's just a sequential stream of pixel data. :) Currently the display is configured for 8-bit transfers. The initial instructions and data used for init are always 8...

r00x

Worked out the error in end, the RPi had not downloaded the jar file correctly. So its all up and running thanks. Will have a go at creating a script thanks. One issue im having is with lag. If I destroy blocks they disappear and reappear then approx 2-4secs later disappear, will check that my GPU ...

r00x

Fascinating stuff! Thank you for all the info and links. I've been cracking on with getting a little OLED to run via SPI and I have another question. At present, I'm not implementing framebuffer support or anything - just simply initialising the display and filling it with colour. What I'd like to k...

r00x

ChrisJW, use NoSpawnChunks like jamesmd95 suggests, and search for plugins which control NPC quantities (the number of animals/monsters/NPCs which can spawn). I've tried one and it seems to cull CPU usage somewhat the more you limit the max number of active mobs.

r00x

tonybkent did you use that script I made? Just wondering as it seems to still be a little temperamental. Hey, it worked well over here... better than the earlier versions anyway :lol: ah, the perils of Notepad eh! One thing I do notice - once it gets to the point of starting the server and creating...

r00x

Did anyone ever make an image file with everything pre done? Now, where's the fun in that? :D Now that you mention it, such a thing would be handy! You wouldn't need an image file though, it would be enough to have a fresh copy of Raspbian installed and then run a single script to set everything up.

r00x

I used 2013-02-09-wheezy without incident - also using the Torrent file (my Internet was atrocious for cutting out).

What keyboards did you use?

What version of the Pi?

Did you ensure the planets were aligned just so before installing?

r00x

Yep, the actual display device most likely does not display any more pixels (physical limitations), but the framebuffer has more pixels and therefore the windows appear smaller (compared to the desktop size) ...the GPU scales the image down to the physical composite resolution. This is correct - th...

r00x

Hello chaps, just got one of these! Very useful and cost-effective for testing GPIO. It works great. I wrote a little bit of code to use the LEDs as a CPU utilisation meter. It's crappily written but it works :D the LEDs will ramp up with CPU load. The code also displays an ASCII graph on the screen...

r00x

Would logic level converters not be necessary? I imagine most old cartridges use signalling levels higher than 3.3V.

Even so, this would be awesome.

r00x

I have no idea how to use those. Perhaps they generate config files after you fire up the server? Grief Prevention seems to be recommended for world protection (watch the video - very impressive), particularly if you don't want to put a lot of time into managing your server's griefproof status. Prob...

r00x

Hi there - just wondering if anyone knows of a way to get high-speed measurements of current CPU usage? My current solution involves calling mpstat and then parsing the result to acquire the CPU utilisation at that moment (this is via Python, btw). This is fine but it only allows a time resolution o...

r00x

Security features would be a good follow up. Don't disable online-mode, for starters :D If you're using CraftBukkit you have access to all the security plugins which can be used to protect your Pi, so griefing could be a thing of the past. However, griefing would be particularly easy within the con...

r00x

A Pi server could do with a practical user limit of about 5. All readers please bear in mind: 1) if users do not stay together the number of chunks to load goes up considerably! 2) every time a player wanders into a new area it will force chunk generation to occur. This is a VERY slow process on the...

r00x

I managed about 9.9MB/s (Sandisk Extreme Pro, one of those UHS-1 cards)... evidently not running in UHS mode

I hear we may get support for UHS soon?

r00x

ChrisJW, are you running the server from within X? It really benefits from running with the bare minimum software you can get away with. For me, it generally runs very well on vanilla: I use a bodged install of Raspbian (my Internet is crap and the install fell over). Whatever, runs great! :lol: I w...
