接口旁路选择器(Serial Interface Bypass Mux)就是个开关,如果拨到上面,辅助的引脚(6、7)就会和通常引脚(8、9、13、14)接在一起,这时STM32是“大哥”,可控制所有设备;反之两路总线分开。 三、软件I2C读取MPU6050 下面是接线图 软件I2C是指用普通GPIO口,手动(软件)翻转电平实现协议,并不需要STM32内部的外设资源...

First, I send a T=1 interface soft reset request and get a correct ATR anwser. Then, I send the applet selection command as indicate in 4.4: - If I set the M bit of the PCB field of the I-Block to 0 (not chained), I get an Nack to my read address byte ...
