How to use I2C for nRF9160 DK with getting sensor Data of MPU9250 or MPU6050?

[jaydip1305]

Hello There,

I want use I2C in nRF9160 for getting MPU6050 or MPU9250 data in it,

I try this Example with change overlay file in it

SDK 1.5.1 and also try with 1.40 nrf\zephyr\samples\sensor\mpu6050\

new overlay file is 

nrf9160dk_nrf9160ns.overlay

&i2c2 {
	mpu6050@68 {
		compatible = "invensense,mpu6050";
		reg = <0x68>;
		status = "okay";
		label = "MPU6050";
		int-gpios = <&gpio0 11 GPIO_ACTIVE_HIGH>;
	};
};

nRF9160 DK --------------MPU6050

pin SDA    30                 SDA

pin SCL    31                 SCA

VDD                              VDD

GND                              GND

Error Failed to find sensor MPU6050

BTW also I2C scanner old example with PIN 10 and 11 but not working

Is There any thing I miss?

This are the info write behind the board nRF9160 DK

PCA10090

1.0.0

2021.6

Either the DTS info is not properly generated or the init function failed. Could you attach the file <sample>/build/zephyr/zephyr.dts? Also could you try to debug the function init_mpu_6050() and see if it fails or not?

BTW also I2C scanner old example with PIN 10 and 11 but not working

 Test the following sample with NCS v1.5.1:

Hi Simon,

Thanks for your Response,

Actually I get the Value of MPU6050 sample but I didn't connect with MPU9250 can you pls help me out
where I need to Change
like prj.conf,nrf9160 overlay file, main file

And I tried I2C example its work fine and I am able to find my I2C device but how can i get the data from it.

I just want MPU9250 data to nRF9160.

Thanks
Jaydip

Recently, it was added support for the MPU9250 in the mpu6050 driver, so the sensor MPU9250 should work with the sample zephyr\samples\sensor\mpu6050:

https://github.com/zephyrproject-rtos/zephyr/pull/32623

https://github.com/zephyrproject-rtos/zephyr/pull/32623/commits/d848227d7b2f2027a39ed64f478f82afcb13e076

However, this change will not be present in NCS v1.5.1, you need to use NCS v1.6.0.

Best regards,

Simon
