Serial obd2 communication

Since there was no project session last week we decided to get together an extra time.
That happened yesterday. Finally we had some success with our attempt to communicate with the OBD-2 bus. We could get a accurate reading for the engine RPM, the vehicle speed, engine load,coolant temperature and absolute throttle position.
We also got the software working on the msp430 it was only the software to write to the computer but it worked. we where able to send "hello world" to the pc.

Here is a picture of hyper terminal after executing the program on the msp.
