I need help for nrf5340 with I2c

[Mr.NCK]

Hi,

I am trying to learn the I2c with nrf5340 PDK. I need to interface Sht20 and Mlx90614 with nrf5340PDK. I need to know the procedures regards this on NRF Connect SDK

Thanks & Regards

Since the Sht20 is not part of the Zephyr repository, you have to add its drivers first before you can use them with your application.

I would recommend you check out this case. Since it is based on version 1.3.0 of the NCS you might have to adjust some things, but the principals should be the same.

I hope this will help you!

Regards,

Markus
