    Taranis : Play the launch altitude of a DLG

    You probably have seem this, but I just got this running on my snipe with the 4 ch receiver and the vario. Playing sound and logging....very nice.

    v1 Original version, for opentx r2940 and up

    Description
    ===========
    This is a program snippet to insert in your DLG program. It does not implement any mix or control function besides playing the launch altitude.

    Requires an altimeter/vario.

    The program uses one global variable (GV2). This GV must be preserved across all flight modes.
    It is meant to be used with a spring loaded SF switch for launch mode, but can be customized to a different one in a single place (see CS6).

    The program is implemented with 8 CF and 6 SF as a state machine of 3 states (0, 10 and 20).

    It performs the following :
    - When the launch switch is held for 1 second or more (enter state 10), and then
    - Resets ALT and ALT+
    - Wait until the launch switch is released then enter state 20
    - Wait until the ELEV gimbal is moved by 10% up or down (indicating the top of the launch is near)
    - Wait another 3 seconds
    - Then play the "ALT+" which is the maximum launch altitude
    - Enter state 0 (waiting for another launch)
    Exception:
    - in state 20 if the ELEV gimbal is not moved within 15 seconds of releasing the launch switch (not really launched?), return to state 0 (witout saying the altitude).

    Have Faboulous flights !
