Are you getting any build warnings/errors or does it all seem to build just fine? To get more familiar with adding I2C to your project, please check out the DevAcademy lesson on that available <a href="https://academy.nordicsemi.com/courses/nrf-connect-sdk-fundamentals/lessons/lesson-6-serial-com-i2c/">here</a>. Here you can see how to customize your SDA/SCL pins as well.</p> <p>Regarding question 2 I&#39;m afraid I don&#39;t understand what you mean here. Can you try explaining some more on what you mean by this?<br /><br /></p> [quote user=""]is 0x28 my slave i2c address (the address nrf52833 will respond when an i2c master will query it ? )[/quote] <p></p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
