Required Libraries:

Copy these libraries into ~/Documents/Arduino/libraries if necesary.

  • DigitalServo (default, it is the same as default Arduino Servo library but with different default pulse value. Included in this repository)
  • Wire (default)
  • PPMReader

Setting Modes

Enter Calibration Mode:

  1. Hold model in equilibrium position unmoving
  2. Move left stick to left bottom, right stick to right bottom:
    |    _____        _____    |
    |   /     \      /     \   |
    |  |   .   |    |   .   |  |
    |  |  /    |    |    \  |  |
    |   \˚____/      \____˚/   |
    |                          |
    
  3. Continue to still hold model unmoving for about 2 seconds

Enter Glide Throttle Setting Mode:

  1. Hold model in air ensuring that wings can move freely
  2. Move left stick to right bottom, right stick to left bottom
    |    _____        _____    |
    |   /     \      /     \   |
    |  |   .   |    |   .   |  |
    |  |    \  |    |  /    |  |
    |   \____˚/      \˚____/   |
    |                          |
    
  3. Let go of right stick and move throttle quickly to desired position, which is set after two exact seconds

TODO:

  • save calibration and glide setting in EEPROM
  • add circuit diagram ...
