根适配器是发出I2C传输的实际适配器,具有父级的所有适配器都是“I2C -mux”对象(引用,因为它也可以是仲裁器或门)的一部分。 根据特定的mux驱动程序,当它的子适配器上有I2C传输时,会发生一些事情。mux驱动程序显然可以操作一个mux,但它也可以与外部总线主机进行仲裁或打开门。mux驱动程序有两种操作,select 和 dese...
i2c-mux-gpio 使用平台总线,因此需要提供一个结构体 platform_device,其 platform_data 指向一个结构体 i2c_mux_gpio_platform_data,其中包含主总线的I2C适配器编号、要创建的总线段的数量以及用于控制它的GPIO引脚。 例如,一个MUX提供了通过3个GPIO管脚控制的4个总线段: #include <linux/platform_data/i2c-mux-g...

很明显、I2C 缓冲器会重新驱动信号、通常用于隔离电容负载、有时还用于弱 I2C 驱动器。 TCA9548A 等器件是 I2C 开关、不会对信号进行"缓冲"(转接驱动)。 I2C 开关/MUX 通常用于执行多级转换或单独的 I2C 地址、以防止地址冲突。 正如诸位先生 指出的、I2C 开关使用起来不太复杂、而且限制/规则也更少。 ...

An I2C MUX with an anti-lock device comprises an I2C multiplexer (I2C MUX) and a reset unit. The I2C MUX is used to connect with a system, which has a central processing unit (CPU), an I2C main control unit, and a plurality of I2C elements. The reset unit is connected to the CPU...
