Hello Everyone,
I need help in the integration of MPU6050 with nRF52840. I know inside SDK one example is present but it worked with nRF52832DK. when I tried to build it with option nRF52840DK_nRF52840 Board. it gives a lot of errors. Please suggest something. The ERROR file is attached here
west build --build-dir f:\RandD\nRF52840\example\mpu6050\build f:\RandD\nRF52840\example\mpu6050
