Pop a mutable reference off the head of a slice, mutating the slice to no longer contain the mutable reference.

Sends the Exit Safe Start command, which is required to drive the motor. Returns 0 if successful, SERIAL_ERROR if there was an error sending.

Returns a number where each bit represents a different error, and the bit is 1 if the error is currently active. See the user's guide for definitions

Returns the target speed (-3200 to 3200). Returns SERIAL_ERROR if there is an error.

Sets the SMC's target speed (-3200 to 3200). Returns 0 if successful, SERIAL_ERROR if there was an error sending.
