为什么MPU9250的WHOAMI寄存器默认值为0x71?
我正在阅读MPU9250的数据表,发现MPU9250内部的MPU6050地址是b110100x。但是当我看到WHOAMI寄存器的描述时,它说默认值是0x71。我无法弄清楚 b110100x 和 0x71 之间有任何关系。
谁能告诉我发生了什么事吗?谢谢~
BTW为什么大家都在地址前面加0,说MPU9250的地址是0x68呢?将 0 放在 LSB 上似乎更有意义,因为 LSB 代表读或写。
I'm reading the datasheet of MPU9250 and I find out the address of MPU6050 inside MPU9250 is b110100x. But when I see the description of WHOAMI register, it says the default value is 0x71. And I cannot figure out any relationship between b110100x and 0x71.
Can anyone tell me what is going on? Thank you~
BTW why does everyone put 0 in front of the address and say that the address of MPU9250 is 0x68? It seems more sense to put 0 on the LSB since that LSB represent read or write.
