haarkon 0:b8dcca3dc509 25 *
haarkon 0:b8dcca3dc509 26 * Any classic RC Servomotor Library
haarkon 0:b8dcca3dc509 27 *
haarkon 0:b8dcca3dc509 28 * This library will operate any servo using a simple PWM to be driven.
haarkon 0:b8dcca3dc509 29 *
haarkon 0:b8dcca3dc509 30 * The library générate a PWM signal with a period of 20ms
haarkon 0:b8dcca3dc509 31 *
haarkon 0:b8dcca3dc509 32 * It may operate in classic mode (eg : min = 1ms, max = 2ms) or
haarkon 0:b8dcca3dc509 33 * in extended mode (eg : Min = 400us, Max = 2,4ms) if you set _extended.
