The additional pins need to be toggled a certain way in orderen-USTelligent Community 13Mon, 31 May 2021 08:59:03 GMTRE: simple integration of GPIO and I2Chttps://devzone.nordicsemi.com/thread/312576?ContentTypeID=1Mon, 31 May 2021 08:59:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:19643d51-cef0-45f0-aaf6-70e24ab60dbfJared<p>What error are you getting?
