Garmon (Gnome/GTK+ Car Monitor) is a tool that lets you connect to an OBD-II compliant vehicle using an ELM327 based scanning device. It supports monitoring live and freeze frame data as well as reading and clearing DTCs. It is written in python.
Great Program. Works very well. The GUI is perfect. Running on my netbook in Mandriva Linux. This is an application I have been looking for, for some time. It is exactly what I was looking for. The developer is quite responsive to e-mails and requests. Great Job, keep up the great work.
