[英]Accessing multiple I2C devices
I have multiple I2C devices on my bus and want to access (read or write) them one by one. 我的总线上有多个I2C设备,并且想要一个一个地访问(读取或写入)它们。 What is the correct way?
正确的方法是什么?
Open and close the bus for each device or keep the bus open and only change the device address for each device? 打开和关闭每个设备的总线,还是保持总线打开,仅更改每个设备的设备地址?
I believe, there is no point in closing and re-opening the bus driver node for each access. 我相信,为每次访问关闭和重新打开总线驱动程序节点没有任何意义。 Use the second strategy.
使用第二种策略。
