Other Parts Discussed in Thread: BQ34Z100
现在项目上,采用了TI的BQ76952加BQ34Z100,2个IC挂在一条总线上和MCU通讯,即MCU共用2个IO口软件模拟IIC分时与2个芯片通讯,现在发现,和BQ34Z100通讯的时候,SCL总是会被强行拉到低电平,导致和BQ34Z100通讯失败。
备注:将BQ76952移除总线就可以正常通讯

您好,请问MCU 是否支持时钟拉伸?https://www.i2c-bus.org/clock-stretching/
大部分用户一直在将这两个器件一起使用,没有任何类似问题,所以工程师这边不太确定您这边发生了什么问题。
