AjK 3:b7d951c6f551 5 /* See example1.h for basic notes.
AjK 3:b7d951c6f551 6 *
AjK 3:b7d951c6f551 7 * This example shows how to use the acceleration and deceleration
AjK 3:b7d951c6f551 8 * profiler to manage changing speed in a simple linear fashion.
AjK 3:b7d951c6f551 9 *
AjK 3:b7d951c6f551 10 * The default accel and decel rates are 0.01/10ms. So when a speed
AjK 4:d69f22061c03 11 * of say +1.0 is demanded, it actually takes 1second to reach that
AjK 3:b7d951c6f551 12 * target desired speed due to the acceleration profiler. Likewise
AjK 3:b7d951c6f551 13 * for deceleration.
AjK 3:b7d951c6f551 14 *
AjK 3:b7d951c6f551 15 * You can adjust the rates by altering the "poll interval" and the
AjK 4:d69f22061c03 16 * accel/decel rates with the API functions.
