NOTE
※ After issuing a motion command, if you are relying on _DMC_01_get_target_pos to
return the pos so you can decide the next step, put in a delay of 10~100ms (this value
can be adjusted based on CPU performance and programming approach) before
executing _DMC_01_get_target_pos to ensure that the data is correct.
