Great! Is there any hard/software you can point to that deals with this? How-to's and what not?

Re: Serial port flow control - need CTS

Seems to me that there are a large number if USARTS, (Universal Synchronous-Asynchronous Receiver-Transmitter), chips out there that could be used for this. The main questions are which, and how. This would bypass most of the hassles, of trying to re-engineer an existant partial solution. There are ...

Re: Connecting to Gertduino via serial

I don't have a gertduino yet, but I've been reading up on it and the alamode boards. One of the things mentioned for both, is the less then fully featured serial intefaces, i.e., no CTS/RTS signals. Most people set these up as 8N1, or 8 bits, no parity bits, and one stop bit. Available are two parit...

Sorry, I meant to say that they wouldn't do
anything _beyond_ lighting the power light, but you're right about it.

Re: Weird Startup Problem

Once I get the version of NOOBS you just recomended, is there any special procedure to follow to install it? I've tried following the directions from several sites, and wound up wasting my time, as they wouldn't even turn on the power light. That's why I'm trying with a commercial card in the first ...

Re: Weird Startup Problem

No problems about the input.

Being as it came in factory packaging, and
has the Raspberry Pi logo on it, I'd guess
it was more like self abuse.

Thanks for the URL. The little bit I've had a
chance to try, hasn't worked, but maybe
later something will. Getting to be my, "nap
time."

Re: Weird Startup Problem

It's a NOOBS card bought from newark.
It's supposed to boot them all, not just
one.

No dialog box is visible.

As I've allready asked, is there any way
to free this turkey up, or do I just swap
it back for one that works?

Weird Startup Problem

Howdy folks; With a new card, and a new R-Pi, What I get when I plug it in, is not Raspbian, but Pidora. Following the advice on one website, to hold the shift key down during boot to change OSs, just gets weirder yet. It refuses to boot at all. If I hold the shift key down, and then insert the powe...

Installation Software/Hardware Question

Howdy Folks; 1. Can the installation software media expansion, (2 Gigs upward), be restricted to a particular range? I've got a 32 Gig USB stick that I'd like to divide up into four 8 Gig partitions, and put a different OS on each, thus avoiding data volatility, by booting up on each instead of havi...

Re: USB Power Supply

Got an update folks; I wanted to learn a little more about USB, so one of the things I found was a wiki about the standard. It had the following to say about powering USB stuff: USB Power Delivery offers the following features: 1. Increased power levels from existing USB's standards up to 100W. 2. P...

Re: USB Power Supply

Thanks a lot, I think I'll try the adapter cable idea
first, (if I can find one, that is).

USB Power Supply

Howdy;

Can the Pi be powered by a USB hub? I have a
hub with 2.5 Amp supply, but it has a post and tube
style power connector, which of course, won't
fit up to the Pi, so I'm wondering about powering
it from the bus.
