Re: can the pi do "software serial"?

I actually did this.

Yeah, it's pretty rough, but I can transmit at 9600baud 8N1 with about ~10% error rate.

Receiving is the tricky part. At 300baud 8N1 I have ~20% error rate sometimes, <5% other times.

Want the code?

Re: Cross compile toolchain

buildroot will output a toolchain for whichever c library you select (from one it supports at least).  I prefer it for my embedded playing: http://buildroot.uclibc.org/

Re: List of ARM Linux software?

<t>Pretty much all open source software for Linux will run on ARM.<br/> <br/> If you run Debian, you can run straight out of the ARM repository if you like.<br/> <br/> If you run Gentoo the packages are built for ARM from portage.<br/> <br/> Just as examples, anyway.<br/> <br/> As for the closed sou...

Re: what will you name your pis?

<t>Bad Wolf, that's a great idea.<br/> <br/> A colleague of mine names his servers after celestial bodies (planets, moons, and lately constellations).  Io, Europa, Ganymede, Kalyke, etc.  This is a pretty limitless way to go, but I find some names difficult to remember and hard for some people to sp...

Re: Qt 5 Alpha

<r>Qt rocks the socks off a sloth.<br/> <br/> There"s also the Qtonpi project (<URL url="http://wiki.qt-project.org/QtonPi">http://wiki.qt-project.org/QtonPi</URL>) which aims to provide tighter integration with RPi on both the toolchain end and (I hope) the QtMobility side (HIL), which would be nic...

Re: Point of Sale Terminal (ssh w/ X Forwarding)

Don't forget the environmental benefits; some stores have ancient PCs running 400~700 watt power supplies, and a lot of them leave these on 24/7, a terrible waste of energy.

Even the database backend could run on a Pi with USB raid storage attached to it, to a certain capacity.

<t>In particular I intend on using RPis as point-of-sale terminals.<br/> <br/> For my store, I have a keyboard, mouse, touchscreen, and printer attached via USB.  The printer then has a 6-pin connector (similar to RJ11, not sure the specification) to the cash drawer to allow opening it to exchange c...
