The Software reads the Sensordata ...

As for a mini keyboard look for a Rii or similar http://riiminikeyboards.com/ . Maybe for communication an XBee might be good the shortest range for one is 120m or about 400f. I don't know alot about XBee but they seem to be the default for transmitting to Arduino's you could ...

... the characteristics of the device you are plugging. These are critical to getting the trigger event you require; in my case a USB UART with an XBee module. I triggered a simply bash script, starting with x+ugo permissions just to get up and running. Hope this is helpful

DBryant

Not played with the GPIO since I've Arduino, XBee radios to play with first:D I assume you have lines in your script like echo "4" > /sys/class/gpio/export echo "out" > /sys/class/gpio/gpio4/direction and these are the ones that are giving grief. ...

... but I believe the ATMega runs at 12MHz on the Gertboard, so is that something I would need to change? The end goal is to have small ATMega + XBee assemblies I can talk to from a Pi central controller...

... My plan was to use a wired interface while I was developing the general system/sensors/software, and add wireless capability with either Xbee or JeeLink. The original idea was to use one cable to daisy-chain the sensors...RJ45 probably, with the I2C lines, 9V, 5V, GND. Then the sensors ...

... Otherwise, you begin with nothing, nada, zilch and you have to learn everything at the lowest level, in RF communications. Better choices include XBee transceiver with all functionality out of the box or, less so, the HopeRF RFM12 with libraries that exist. Either is 1000-fold more sophisticated ...

... the remote end. It needs to read data from an MCP3008 ADC and possibly tigger some action remotely to an i2c attached chip. I was considering the xbee, and the jeenodes (similar price i think) as RF protocols but if I can cut out the chip middleman my costs and complexities go down.

prussia

Hi,
How have you fared in the last few months? I'd like to create an RF node that reads sensor data and just sends it to the Pi. Price is a factor and was hoping this chip would work better then the Xbee to save on costs?

Curious to see how you've progressed on the RF front

currymuetze

... but ordered my self the 512MB Version. The reason for this is that I needed a cheap computer to run PROCESSING which controls my Arduino via XBEE. Hope I will get this working but as I read meanwhile its not problem to install PROCESSING. Anyways, after reading quite a lot I am thinking now ...

JimDod

... so I believe X windows is not starting. I can ssh to the rpi further exam I think the perl program is running it is just not communicating to the XBee via the GPIO serial lines. could some other process be grabbing these? I have all the ttyAMA0 stuff removed from /boot/cmdline.txt as well as disabled ...

JimDod

I have a system set up to do a autologin that runs a Perl program servicing an XBee and a USB camera to serve snapshot pictures. this boots and runs fine if I have a USB keyboard and a HTMI monitor. When I unplug (headless) them it does not seem to be working, ...

... A library and firmware is available to provide a transparent serial stream interface for the RFM12B so that it can be used as easily as an XBee or Ciseco XRF/URF radio module. More information, including links to the open-source software and hardware design files, can be found on my blog: ...

What do I need to keep in mind for moving the MCP3008 to an xbee to communicate sensor values remotely to the Pi (I'm not there yet but trying to think ahead). I love my Pi and seeing the sensors transmit data ...

... a low temperature tank reading from the centre on Pi1 and transmit to Pi2 where it would fire the boiler & pump circuit. I jave been looking at Xbee controls for this but due to the rather unique structure of the building (underground & made of 24" crushed chalk walls) I dont think any wireless ...

... RPi was the micro USB cabel and the HDMI cable. After I get familiar with the RPi I will be concentrating on interfacing it with the Arduino and XBee. Hope to hear from you soon, Beware of zealots and prophets!

sysjay

I chose the nrf24l01 becasue it was much cheaper that xbee. I bought a pair of r24 transceivers from ebay for less that $7.

I also chose because of the library support. I was able to find more info for r24 online especially for the rpi interfacing.

... I am relatively new to this area. If I were to create zigbee network using PI, which one would you recommend me ? The options which I can think of XBee, Jennic and TIs. They all have their own Pros and Cons. If I want change the device on the fly and etc, easy app development :), which one is better ...
