    While playing dirt 3 the game engine application often stops responding and crashes. Sometimes it is enough to just exit the game and open game engine again, while other times when I try to start game engine again it says it is already running and I have to restart the computer. I rarely get a full race done before game engine crashes, any ideas?

    I am running an arduino based system connecting at 115200bps, 8 data bits, zero parity

    Is the Ard locking up too, I have had a similar issue while running a dash app with the Ard, if the serial port falls over because of the Ard, can cause the engine to crash.
    Ard related, why I don't use them for motion, dash only applications.
    Solution try running your Ard at a lower baud rate or adjust the packet rate so the Ard doesn't lock-up and stop the serial port.

    I have got this issue too with Ard R3 and a servomotor (doing a phisycal RPM meter). Before 30 minutes of a race (or training) Game Manager crashs. Baud rate is set to 57600 :(.
    I'll try later with 9600 or slower.

    Ok with V1.2 SimTools and Game Dash tested under Windows 8 and 7, I have not had this issue again.
    But in GameDash if a weird value comes in like a -1 on rpm as where some games start, if you don't have the right script in place, like Replace -1 0 . Then the Ard locks up because no checksum or serial error in code to catch the issue. Simply the Ard would lock the serial port and I have to close the GameDash and the Game Manager and restart the Ard and restart the Manager and Dash.
    A simple Serial.flush when the data is incorrect or now I use arrays and checks in code to make sure data is correct so the Ard doesn't lock up the port. Another way is have an end of command maker so it reads the serial until it reaches that like "~" then it know it has all the data to compose to a number, but depend how you are doing it.

    I have an example that is very stable, runs 2 servos for a sim model, check the code out. And use of it all or none as you please.

    Thank you eaorobbie for the informations. I'll try 9600 and flush data on every end of loop on next event :)
    I got your example for 2 servos, very usefull and well commented ! thx a lot !
