Question

我想在我的MPU 6050上激活94 Hz带宽的低通滤波器。通过读取documentation（第13页），它表示通过将所选数字写入地址1A来激活适当的带宽（第6页）。

这在虚空设置中是否可以这样做？

Wire.beginTransmission(0x68);
Wire.write(0x1A);  // 
Wire.write(2);     // 
Wire.endTransmission(true);

亲切的问候，

假设您只想设置带宽设置而不是FSYNC位，那么您应该写：

Building file: ./exec/main.cpp

其他配置寄存器可以类似地设置，但您必须知道位打包字段并正确连接它们。
