Finally all of the necessary components have arrived and I can start trying to run things on the raspberryPi. So I will mostly with working with this setup for a little while. It took a little while to get things going, but someone posted a great link on the CompArts forum to a very handy guide to getting openFrameworks setup on the pi, and after some time waiting for things to compile, I finally managed to get one of the examples to work. Which is pretty great. Now the challenge is getting the program/s written on my laptop to work on the pi. Easier said than done it would seem...for starters the so-called native rPi camera (the one plugged in to the camera socket on the pi) does not work with the openFrameworks video grabber (it might work with a USB camera but I've not tried this yet), and as I'm working with one of these kinds of camera for low-light vision, getting this working is pretty essential. Luckily a bit of research unearthed a handy add-on which should enable me to use this camera in OF. I've also heard-tell of the abilty to cross-compile to the pi - in other words, using your laptop to speedily compile the program but in a way which mimics the file system of your rPi, thus allowing you to run a program straight away on the pi without needing to compile first (which takes a fair while longer on the pi, as I've discovered!). This step certainly isn't essential but it would be a pretty good time-saver and would help massively for de-bugging, especially for add-ons designed specifically for the pi. I have no doubt that I will encounter several other intriguing quirks when working with the pi, but so far off to a good start.
