Re: Sending serial commands to a Raspberry Pi over WiFi

If you have an XBee FTDI adapter, or XBee Explorer USB then a straight TX to DIN and RX to DOUT with 3v3 power and Gnd nicked from the Pi will work well. I haven't tried using the XBee as a tty terminal access (similar to SSH) but I have used it to communicate with the Pi wirelessly over XBee by fre...

Re: Easy Arduino - Raspberry Pi serial over GPIO

Hang on - in the example scetch did you mean

Code: Select all

Serial.begin("9600");
or

Code: Select all

Serial.begin('115200');
?? I'm just wondering, as the baud rates should be the same, at least I think...
Thanks, Angus.

Re: Impact on the desktop world

True, ARM is catching up with i36 and AMD64 architecture, and in 5 or so years, it will be faster. But at the moment, the rpi is far too low power to be able to do substantial computational operations, such as running servers. But the (relative) simplicity of using ARM devices means that in the long...

Re: Ubuntu on Raspberry Pi

...done a tad of research... and Ubuntu's minimum requirements for more recent releases are above what the Pi can provide. However, you could try and put 6.06 Dapper Drake on it, as it's minimums are 256MB RAM and 3GB Memory. But the overheads of running GNOME would make things like web browsing imp...

Re: Ubuntu on Raspberry Pi

As Ubuntu is based (ish...) on Debian, and really the main reason for wanting Ubuntu is that it looks nicer than Debian (well, I think it does) and it has GUI perks like Unity (Although the Pi would have to use Unity 2D or go without, performance depending) then it could be possible to make the Pi's...
