Hi Guys,
I cheated and used node.js with a module called node-serial. I discovered that you need to disconnect the serial port from the console before you can use it (edits to /etc/inittab and /boot/cmdline.txt). I imagine you'd need to do this in a python environment too. minicom was very useful for prodding the serial device to make sure it was working before I pointed my program at it.
Regards, Paul

HTH, Omer.

I need some help from one of you Arduino gurus.
I want to talk to the Arduino serial interface from a Fedora
Linux system. I
know how to do the Arduino side, using Serial.available, Serial.read, Serial.write etc.
My problem is how to talk from the Linux end. All the examples I see are Windows based and use Thierry Schneider's Serial C++ Library for
Win32. What
do I use as the Linux equivalent?
It's not as simple as just writing the the Linux device (in this case /dev/bus/usb/004/081). I suspect I need something rather cleverer, but I don't know what it is.
Any help much appreciated. I'm trying to help a youngster set up an Arduino based face tracker, driven by OpenCV face detection on the Linux box.
Thanks,
Jeremy
