Essentially, a design change means that we want to combine what were two distinct I2C busses (and so, 2xSDA and 2xSCL pins mapped on the NRF52en-USTelligent Community 13Mon, 13 Nov 2017 15:47:19 GMThttps://devzone.nordicsemi.com/thread/105411?ContentTypeID=1Mon, 13 Nov 2017 15:47:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:94fb4ff4-040c-4d8b-ac20-b615125d4536ovrebekk<p>Hi</p> <p>Having one pin duplicate the state of another is possible, by using the GPIOTE and PPI modules, but if you need the mirroring to go both ways I am not sure how simple it would be.</p> <p>Couldn&#39;t you just remap the I2C interface to one of the two buses, depending on which I2C slave you are talking to?</p> <p>Best regards<br /> Torbjørn</p><div style="clear:both;"></div>
