Sorry, I did not know that the MPU6050 driver did use a deprecated TWI driver. I do not recommend using this. Please have a look at this thread. You should be able to rewrite the driver to work with the standard TWI master driver, without too many changes. I would also recommend you to take a look at this GitHub repository by Martin, which contains drivers and examples for various MPU models.

but i fix it and add new patchs into Makefile

  $(SDK_ROOT)/components/drivers_ext/mpu6050/mpu6050.c \
  $(SDK_ROOT)/components/drivers_nrf/twi_master/deprecated/twi_hw_master.c \
  $(SDK_ROOT)/components/drivers_nrf/twi_master/deprecated/twi_sw_master.c \
  $(SDK_ROOT)/components/libraries/uart/app_uart_fifo.c \

and

  $(SDK_ROOT)/components/drivers_nrf/twi_master/deprecated/config \
  $(SDK_ROOT)/components/drivers_nrf/twi_master/deprecated \

and i have error

Hi,

Are you trying to include the MPU6050 driver that is present in the SDK? This driver does not have any functions with the name InitMPU6050. Try with mpu6050_init(0x68) instead.

If you are trying to add another MPU6050 library, you need to include the path to the correct header files in your Makefile.

Best regards,

Jørgen
