Dear All I finally managed to get all the equipment together and connected all the stuff mentioned in this blog. On my laptop using Java I am running the following program: package twowayserialcomm; import gnu.io.CommPort; import gnu.io.CommPortIdentifier; import gnu.io.SerialPort; import java.io.IO...

I look forward to start working on my project. I am writing a blog detailing the progress of this project on: http://piprojectsblog.wordpress.com. Would it be possible if you direct me to the right direction on where I should look to get the right information for setting up my devices please? Thanks...

Ok that is a relief. I though I had to incur further expenses... hehe

So with the OS installed on the Pi, I just need to switch it on, leave it on the "desktop screen" and run the java program from my laptop and the GPIO controls the relays?

Thanks

Is it still possible to do what I have in mind with the raspberry pi even though it is not the b+?

Thanks

Hi and thanks for the reply.

I am using a 512MB Raspberry Pi Model B Revision 2 Computer - Rasberry PCB BOARD 2.0.

Hi All, Ok so now I bought all the hardware necessary to control the Pi using Java from my macbook. I now need to know the configuration the Pi needs to be in for this to work. By configuration I mean... Does the Pi need to have an OS running, if yes is there a particular OS which works best for my ...

That is helpful.

I have also looked for "FTDI USB adaptor" which in certain forums are highly recommended.

These use RXTX communication terminology which converts to serial communication.

Thank you for your reply.

I have done a very intensive research with no success.

I can't figure out how I am going to program or instruct the Pi to control these relays using java running on another device....

Has anyone done something similar to this?

Thanks

Hi, I wanted to ask whether it is possible to control the raspberry pi using a java program being run on a pc with either windows or Mac Os. My intention is to connect several relays to the Pi and control them with Java. The interface between the Pi and the laptop has to be a usb cable on the laptop...
