    • A method for data access via an inter-integrated circuit (I2C) protocol. The method includes receiving an I2C read command at an I2C slave device, where the I2C read command is from an I2C master device. The method also includes reading stored data from a storage device in response to receiving an I2C read command. The stored data is at a first location in the storage device corresponding to a value in a register array pointer in the I2C slave device. The stored data is transmitted to the I2C master device in response to the reading. The method also includes receiving an I2C write command at the I2C slave device, where the I2C write command is from the I2C master device and the write command includes master data and a slave device register address. The master data is written to the storage device in response to receiving the I2C write command, with the master data being written at a second location in the storage device corresponding to the slave device register address.
    • 一种通过集成电路(I2C)协议进行数据访问的方法。 该方法包括在I2C从器件上接收I2C读命令,其中I2C读命令来自I2C主器件。 该方法还包括响应于接收到I2C读取命令从存储设备读取存储的数据。 所存储的数据位于存储设备中与I2C从设备中的寄存器阵列指针中的值相对应的第一位置。 存储的数据响应于读取而被发送到I2C主设备。 该方法还包括在I2C从器件处接收I2C写命令,其中I2C写命令来自I2C主器件,写命令包含主器件数据和从器件寄存器地址。 响应于接收到I2C写入命令,主数据被写入存储设备,主数据被写入存储设备中对应于从设备寄存器地址的第二位置。

    • A communication system, method and program product are provided for establishing an extended bidirectional communication bus between a first device and a second device. The communication system includes decomposition logic for decomposing a single line, bidirectional data communication bus into a unidirectional transmit data communication bus and a unidirectional receive data communication bus. A differential communication subsystem is connected to the two unidirectional buses for extending the length thereof, and recomposition circuitry is connected to the differential communication subsystem for recombining the extended unidirectional transmit data communication bus and the extended unidirectional receive data communication bus to reestablish the single line, bidirectional data communication bus. The decomposition logic, differential communication subsystem and recomposition circuitry are implemented transparent to the first device and the second device and without use of a data direction control line.

    • A system and a method for starting a brushless DC motor are provided. The method includes applying commutation pulses to at least two phase coils to induce a rotor to rotate to a starting position and then de-energizing the at least two phase coils. The method further includes applying commutation pulses to at least two phase coils to induce the rotor to rotate from the starting position in a predetermined direction. The method further includes de-energizing all phase coils for a first time interval after the rotor is rotating and sampling a back EMF signal in at least one of the phase coils to determine a first value indicative of an electrical period of the back EMF signal or a portion of an electrical period of the back EMF signal. Finally, the method includes applying commutation pulses to at least two phase coils for a second time interval, the second time interval being based on the first value.
