If it's a true linux PC you can just scp/ftp over binaries, just as easy as you could over USB with an Arduino. What it probably lacks is the digital and analog IO ports that you can easily access in the Arduino.
- wccrawford 15y agoRight. Actually, I was thinking of putting the data on the SD Card, but it doesn't really matter how it gets there... Just that there are IO ports to mess with. I suppose a USB device could be made for that, though... If it doesn't already exist.
- sasvari 15y agoactually it does exist, i.e. the SerIO from SparkFun (which is a pretty neat device, btw): http://www.sparkfun.com/products/9521 http://www.sparkfun.com/products/9521 but then you're back again at arduino, with the SerIO having a higher price tag than the device itself.

- noahc 15y agoThat's a lot cheaper than something like this: http://www.phidgets.com/products.php?category=0&product_id=1019 http://www.phidgets.com/products.php?category=0&product_...
- wccrawford 15y agoWell aren't they just awesome? :D I'm starting to really like them. For twice the price of an arduino, the $25pc+SerIO could still be a really nice way to create some entertainment. In fact, since it has audio out and SD card, it would already be cheaper than another project I was working on. lol The Arduino would probably boot faster, though, so that's a consideration as well.
- adestefan 15y agoIt depends on the chip they use. Most have tons of GPIO lines to use and they're pretty simple to access in Linux, even from user space. Now the question is if they'll expose them on the board.
- jamesgeck0 15y agoFrom the elinux wiki: There are approximately 16 spare GPIOs, which are brought out to 1.27mm pin-strip. Voltage levels are 3v3. The connector choice is deliberately annoying to connect to directly; there is no over-voltage protection on the board so the intention is that people interested in serious interfacing will use an external board with buffers, level conversion and analog I/O rather than soldering directly onto the main board. We also bring 2x I2C (3v3), I2S and an SPI (3v3) interface out to the same connector. We support one slave interface for I2C and one for SPI. http://elinux.org/RaspberryPiBoard http://elinux.org/RaspberryPiBoard
- jamesgeck0 15y agoThe device will have USB and HDMI ports, in addition to a headphone jack. You'll be able to use it like a (tiny, cheap) desktop PC. Edit: I'm not sure how easy it'd be to wire up sensors and such to USB. Don't some of Apple's ear buds send commands over the headphone jack? Does that require a special jack, or could it be done easily with normal hardware? Edit 2: Would the GPIOs work for this?

- waitwhat 15y agoSending commands does require a special jack.
- seclorum 15y agoIf its a true linux PC, you can just put the compiler onboard, where it belongs, and forget entirely about any further steps being required.
