https://devzone.nordicsemi.com/f/nordic-q-a/43558/how-can-i-do-i2c-initialization-on-any-gpio-pin-in-nrf52810Hello all, I am right now working on one project. where i use BT832 in which nrf52810 BLE ic use. i use segger studio in windows 7. For reference i use nRF 5.2.0 SDK. right now i am doing i2c communication of temperature sensor(lm6bd) with ble boarden-USTelligent Community 13Wed, 13 Feb 2019 15:07:22 GMThttps://devzone.nordicsemi.com/thread/170940?ContentTypeID=1Wed, 13 Feb 2019 15:07:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:950c04c2-b12d-43ac-bbdf-bee13ae2bb10Simon<p>If you are using UART logging through the interface MCU (<a href="https://www.nordicsemi.com/DocLib/Content/User_Guides/nrf52832_dk/latest/UG/nrf52_DK/vir_com_port">link</a>), the GPIO pins 6 and 7 will be used for respectively the TXD and the CTS line. If this is the case for you, you either have to disable UART logging or use some other pins.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/170400?ContentTypeID=1Mon, 11 Feb 2019 14:20:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dd0d19fa-a4ef-4064-bcb1-417dfce5c888twihtronics<p>you can simply just change the pins like shown below</p> <p></p> <p><img src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/pastedimage1549894629669v1.png" alt=" " /></p> <p></p> <p>Just change .scl and .sda the&nbsp;twi_config variable declaration.</p> <p>I have used EXT_SDA and EXT_SCL which are defined above.</p> <p>No other changes should be required.</p><div style="clear:both;"></div>
