Newbie question on PiStorms API.How does one control the start/stop of two motors simultaneously? MINDSTORMS permits operations on two motor ports simultaneously with fundamental calls. What would be the conceptual equivalent with PiStorms? I see setSpeed and hold in the PiStorms API. I could use these for my purpose in successive calls. But beyond that the nuances escape me. (Sorry for not reading the PiStorms docs more closely). Thanks.
