Car diagnostic software for vehicles with OBD2 compatible interface.

• now we can run two actions. Program looks for serial interfaces and lets the user to select one. Then it runs the action.
• report creates a text file in the current directory containing all implemented values.
• clear_trouble_codes erases the saved errors.

sudo java -jar ./java-cardiag-0.0.1-SNAPSHOT-jar-with-dependencies.jar report;
sudo java -jar ./java-cardiag-0.0.1-SNAPSHOT-jar-with-dependencies.jar CLEAR_TROUBLE_CODES;

• support for most of today's operating systems
• communication via USB ELM327/OBD2 car interface, probably other in future
• stability
• simple startup, no system modifications needed (only JRE6 and higher)
• pretty maintainable code covered by tests, both unit (without real serial interface) and integration (with interface and car)
• open source free code

• how
• only available hardware for testing - ELM327 clone (1.5a)
• only few available cars for testing - Lada Kalina 1.6 8V 2007, Škoda Fabia 2010, Ford Focus 2007, Seat Ibiza 2001.
• need help with a selection of the license ... GNU GPL v3? EPL? BSD? MIT?

Port name - /dev/ttyUSB0; Method name - openPort(); Exception type - Permission denied. (Linux)

• sudo gpasswd --add ${USER} dialout
• or run the program with sudo.

• early development.
• can reset error codes
• can produce a report file with the current values
• version 0.0.1 will be released after I will fix my problem with my car (P300, P303, P304) ... or later, in 2017 ;)
• if someone will start implementing GUI, many people will be finally happy ;)
