denis2nis 2:02f3323a107d 70 * The servomotors are daisy chained to a serial link of the target
denis2nis 2:02f3323a107d 71 * microcontroller. The class ensures the initialization of serial link
denis2nis 8:e74ef93ae660 72 * and the management of communications mainly to control rotational
denis2nis 8:e74ef93ae660 73 * speed of servomotors.
denis2nis 8:e74ef93ae660 74 *
denis2nis 2:02f3323a107d 75 * Transmission of messages to the servomotors is blocking while
denis2nis 2:02f3323a107d 76 * reception is non-blocking thanks to the use of an interrupt routine.
