Re: How To Make A Raspberry Pi Minecraft PC Server

Snoop05 - thanks for posting that advice about SpigotMC. It seems quite easy to build and run on the Raspberry Pi now, and I was able to connect to an instance running on a Pi 2 to do some light testing. I was wondering if you or anyone else has any advice about additional setup. For example what pl...

Re: A MineCraft Server Image - MineCraftPi

@Rionoskae - thanks for taking the time to make this. Maybe I'll just configure the DHCP server such that the Pi gets the same IP every time. I didn't want to take the time on Sunday.

@Rionoskae - we tested out your image on Mother's Day. We only had two people logging onto the server so it wasn't under heavy load. Anyways the kids were playing with it for 2-3 hours and the server never had any problems whatsoever. My older nephew said that he didn't like to play minecraft anymor...

Re: A MineCraft Server Image - MineCraftPi

I downloaded this, confirmed that it boots, and plan to try it out with my 2 nephews over the weekend. It it works out, then the whole rig may go home with them as part of a birthday present. I'll post next week unless something unexpected happens and I don't get a chance to try it out.

Re: Ultrasonic rangefinding with Ping

I see that pigpio can handle this sort of thing based on William Henning's SPRITE article in the Jan 2014 Servo magazine. I have to admit that I didn't look at Tank's GPIO module yet, so don't know if it can easily perform this sort of task. Henning is on the Parallax forums a lot, so I expected to ...

Ultrasonic rangefinding with Ping

Here is a quick example of how to interface to the Parallax Ping sensor. It would be nice to package this up a bit, but maybe it's useful as-is. It's the first Basic/assembly program that I've written on the Pi. REM This is an example of how to use Parallax Semiconductor's REM PING Ultrasonic Distan...

Re: Event detect status register

kayel - it's quite common to have registers of type RW1C or read/write 1 to clear. This is done for a reason, which is to prevent race conditions. Let's take a simple example: v = REG v &= mask REG = v If an event occurred and set a different bit after the initial read "v = REG", then the final writ...

I hope that I don't make an embarrassing mistake… x [microseconds] = N [cycles] * (1 [sec] / M [cycles]) * 1 million [microseconds/second] = 1000000*N/M [cycles] So you have N = 150, the question is ...

Book - Raspberry Pi RISC OS System Programming Revealed

Is anyone planning to checkout a copy of Bruce Smith's newly released book "Raspberry Pi RISC OS System Programming Revealed" anytime in the near future? I would be interesting in hearing opinions of anyone who gets a copy. Plus it's been quiet in this forum, and the book deserves a mention.

Re: RISC OS Assembly Tutorials.

@DavidS - interesting. I've lived in CA since about '72 and have never seen an Archimedes. I think that one of my friends must have been working on the Newton project sometime around the time you got the Archimedes. My understanding is that Apple influenced the ARM ISA in the early days.

Re: RISC OS Assembly Tutorials.

DavidS - totally offtopic but I have to ask you how you were exposed to RISC OS in Kansas? It sounds as if you are a longterm user. (I was actually born there, but we moved away shortly afterwards.) I never ran across it until the RPi came along.

Does anybody know where I can find a copy of the BBC Basic manual that would be most appropriate for using with the Basic provided with the Raspberry Pi RISC OS download?

Re: STEM PiBot Project

Cool. You can get ultrasonic sensors for about $3.50 now, so those should be nice to add. How will you interface to them? Are you adding a separate microprocessor? I'm not sure how well the Pi can support peripherals requiring accurate timing. It's a cinch for chips like the Parallax propeller. It c...

Re: Is Scratch really viable on Raspberry Pi?

@timrowledge: thanks for the update. Is all of the RISC OS graphics processing (e.g. even BitBlt) being done by the ARM right now? So maybe we'll see large improvements in the future?

For RISC OS I downloaded Squeak3-9b-RISCOS.zip and followed your instructions, and then downloaded Sc...
