1. A drive apparatus comprising:
a controller configured to function as a host; and
a first driving device group slave-connected via a clock signal line and a data signal line to the controller to drive a first object to a first target position, wherein
when driving the first object to the first target position from its current position, the controller is configured to set a plurality of via points obtained by dividing a path from the current position of the first object to the first target position, and execute the driving in a stepwise manner, passing through each via point in the plurality of via points sequentially,
wherein when the first target position is changed to a second target position before the first object reaches a last via point in the plurality of via points, the controller is configured to drive the first object to a subsequent via point immediately after the change of the first position to the second position, and then drive the first object to the second target position from the subsequent via point instead of passing through remaining via points in the plurality of via points towards the first target position.
