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...

SPI是串行外设接口(Serial Peripheral Interface)的缩写。I2C总线是一个真正的多主机总线,总线上多个主机初始化传输,可以通过传输检测和仲裁来防止数据被破坏 。 2017-12-06 11:39:08 如何去使用STM32的硬件I2C 时钟使用常规的72M,这部分配置很多芯片都一样I2C的配置也是普普通通,保持默认就好,不使用DMA传输I2C初...
