nrf 9160 dk for I2C scanning for address.

[Captain CK]

Hello,

I am using nRF9160 dk for prepare a program to I2C scanning for address. Can any one give a guide for start this task. Moreover, I am using Zephyr kernel on nRF9160dk, SEGGER SDK. 

Thank you

Hi,

I have a sample here, https://github.com/sigurdnev/ncs-playground/blob/master/samples/i2c_scanner/src/main.c, it was created almost 1.5 years ago, so some minor changes might be needed if you are using a recent version of nRF Connect SDK.

Sigurd,

Thanks.

Hello Sigurd,

The program you share build and compile well. But after debug started, program didn't run from

"printk("I2C: Device driver not found.\n");" line. 

Is the problem on my nRF9160 dk. 

Also, can you give a short summarize of this code. Because I feel confused how the program flow.

Thanks.

Hi,

"printk("I2C: Device driver not found.\n");" line. 

Then something is not configured correctly.

I can update the sample. What version of NCS are you using ? v1.8.0?
