Re: Enable UART flow control by default (on boot?)

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...

Enable UART flow control by default (on boot?)

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...

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.

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...

Re: Primary display via SPI?

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...

Re: Primary display via SPI?

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...

Re: Minecraft server - How To

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.

Re: Minecraft server - How To

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.

What version of the Pi?

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

Re: Screen Resolution

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.

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

Re: Minecraft server - How To

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...

ChrisJW, are you running the server from within X? It really benefits from running with the bare minimum software you can get away with.
