Motor control circuit

摘要

In some preferred embodiments, a motor control circuit 1 for controlling driving of a plurality of motors 3 and 4 includes a serial communication circuit configured to perform serial communication with an outside, a received data storage 15 configured to store data from the serial communication circuit, a motor mode setting holding circuit 16 configured to store motor mode settings which decide operations of the motors, and a detection circuit 24 configured to detect changes in driving pulse of the motor. Depending on the detected result of the detection circuit 24, the data stored in the received data storage 15 is transferred to the motor mode setting holding circuit 16.

1. A method for driving at least a first motor, comprising:
storing an address value for a first slave integrated circuit at a first location associated with the slave integrated circuit, the address value associated with the slave integrated circuit including an address value for the first motor; serially receiving address data from a master integrated circuit at the address matching circuit; confirming that the address data from the master integrated circuit matches the address value for the first motor stored in the address matching circuit; allowing sequential transmission of motor drive data from a master integrated circuit in response to the address data from the master integrated circuit matching the address value for the first motor stored in the address matching circuit; transmitting a stop condition for terminating the motor drive data being forwarded to the slave integrated circuit in response to completion of communication for setting drive values for a first driver for the first motor; and using the motor drive data to control the motor.
