Raspberry Pi

lavalamp · 2013-09-22, 06:54

Wheee! Just ordered myself a Raspberry Pi, should arrive within a week or so.

Thought I might have a go at writing an implementation of the prime counting function for it so I can get my self-referential kicks. After that, I don't know...

Has anyone else here toyed with these?

Well that arrived much sooner than I expected. Now begins the tinkering.

A friend of mine got his to play old arcade games using the GPIO to connect a joystick. You may want to search around a little more but I believe he followed something like this.

Heh, yes Budgie, just the one.

I'm not much of a hardware tinkerer, so I'll probably be leaving the GPIO pins untouched, however I did buy a book that teaches programming on the Pi, specifically in Python which I've heard is all kinds of sexy. Figured I'd get a feel for the device and learn a new language at the same time.

You might be interested in experimenting with programs like msieve that compile with pure c if necessary.

Does the latest version of Pi run the ARM Neon? I'm currently in the process of porting my Mlucas 128-bit SIMD assembler macros to that architecture, using an Odroid C2. Hope to have that releasable sometime this Fall.

I think that would depend on the operating system used. I think the default raspbian is still 32-bit.

Yes, I have a Raspberry pi 3 and I have installed openSUSE 64-bit (AArch64) on it in order to test the ARM Neon popcnt algorithm used in my libpopcnt.

Good to know - I will announce any beta code release in the Software -> Mlucas subforum. Based on my progress rate so far, late September looks like it will the absolute earliest possibility for such. Speaking of which, back to work...
