在最后一张图片里提到,
The MPU-9250 can be put into Accelerometer Only Low Power Mode using the following steps:
(i) Set CYCLE bit to 1
(ii) Set SLEEP bit to 0
(iii) Set TEMP_DIS bit to 1
(iv) Set DIS_XG, DIS_YG, DIS_ZG bits to 1
The bits mentioned in the steps (i) to (iii) can be found in Power Management 1 register (Register 107).
In this mode, the device will power off all devices except for the primary I2C interface, waking only the accelerometer at fixed intervals to take a single measurement.
但是第三步的寄存器在寄存器组里没有见到。。。。 |
