mapellil | 7:d79cbeda2982 | 49 | This module returns one of the states defined in ::Gestures_Motion_Code_t based on a programmable range threshold. |
mapellil | 7:d79cbeda2982 | 50 | When a transition state is returned (::GESTURES_MOTION_RAISE_UP or ::GESTURES_MOTION_DROP_DOWN), it also returns the |
mapellil | 7:d79cbeda2982 | 51 | duration (in ms) of the previous state. For instance, assuming ::GESTURES_MOTION_RAISE_UP is returned, duration is |
mapellil | 7:d79cbeda2982 | 52 | the time the state ::GESTURES_MOTION_DOWN_STATE has been maintained before the down=>up transition. |
