Abstract

本申请公开了一种控制方法及装置，其中方法包括：主机确定需要控制的目标设备后，可以通过I2C接口向主控设备发送指示信息、控制命令和目标设备的寄存器的地址，进而主控设备可以将指示信息、控制命令和目标设备的寄存器的地址封装后发送给主控设备连接的从设备。采用该方法，由于主控设备可以通过一条消息将指示信息、控制命令和目标设备的寄存器的地址发送给从设备，进而由从设备基于指示信息来确定目标设备是否为自身或自身连接的外围设备，从而能够实现对从设备或外围设备的快速控制，且具有较强的适应性，比如可以适用于各种复杂的拓扑结构。此外，当需要切换目标设备时，可以再次执行上述方法，从而使得切换效率较高。
