This tutorial shows several small tricks:
- How to easily compile from the command line using the project Makefile described in my post about command line compilation (extension of Wim's post).
- How to send integers (2-bytes long) over the serial port (1-byte messages).
- How to plot "real-time" the data in the serial port using GNU Octave .
In case of questions you can ask them here, or you can contact me in the #dwengo channel at irc.freenode.net using any IRC chat client (e.g. Pidgin ) or a web based client .
