DBus server for serial communication with ATMega

• dbus
• python-dbus
• pygtk
• apscheduler (pip)
• pyserial (pip)

Serial ports in Linux are mapped as device in /dev folder as ttyS*. By default all devs are owned by root, and not-root user cannot access it. To allow user control serial port you can:

• change owner of /dev/ttyS*,
• add your user to serial ports owner group (recomended way).

To add user to right group you need:

1. Get know what group owns ttyS*: ls -l /dev | grep ttyS

2. Add user to group: usermod -a -G group_name user_name

Don't forget about logout and login again after this operation!
