MPU-9250 SPI-итнерфейс


Recommended Posts

Подскажите, как инициализировать SPI-интерфейс у MEMS-датчика MPU-9250.
В документации сказано, что по умолчанию он находится под I2C-интерфейсом и что бы переключиться, надо изменить регистр. А та часть главы, на которую приводится ссылка, отсутствует.
Note:
To prevent switching into I2C mode when using SPI, the I2C interface should be disabled by setting the
I2C_IF_DIS configuration bit. Setting this bit should be performed immediately after waiting for the time
specified by the “Start-Up Time for Register Read/Write” in Section 6.3.
For further information regarding the I2C_IF_DIS bit, please refer to the MPU-9250 Register Map and
Register Descriptions document.
