https://devzone.nordicsemi.com/f/nordic-q-a/15193/uni-o-interface-with-nrf52Hi Nordic Developers.. I am using nrf52 with softdevice 132. In my project i am using external EEPROM(Microchip 11AA010) that uses UNI/O protocol and Single I/O Serial Interface Bus. i can&#39;t find any example nor any library for it. can anyoneen-USTelligent Community 13Mon, 18 Jul 2016 08:48:06 GMThttps://devzone.nordicsemi.com/thread/58005?ContentTypeID=1Mon, 18 Jul 2016 08:48:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f5e6d1d7-27be-4f74-9a5d-fea106adb62aved<p>ok thank u</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/58004?ContentTypeID=1Mon, 18 Jul 2016 08:42:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9dc95325-3008-4f70-a91f-7b21d7ca891cRK<p>no nobody can help you - there&#39;s no peripheral for that type of interface on the chip, so you have to write your own code to drive it, which won&#39;t be easy with the softdevice and may actually prove just not to be possible at all.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/58003?ContentTypeID=1Mon, 18 Jul 2016 08:38:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bec9baa7-adbf-4601-a9c3-e2be8301198eved<p>Thanks RK for Reply..</p> <p>yes i have to use that EEPROM(Microchip 11AA010) chip..</p> <p>i am not sure from where to start.</p> <p>Any Nordic Employee Can help Me?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/58002?ContentTypeID=1Mon, 18 Jul 2016 07:20:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:62933f8c-ba95-44d6-8626-01fd91a77edcRK<p>well there&#39;s no native support for it and so you&#39;d have to bitbang it. Quickly reading over the protocol it seems to have some fairly tight timing requirements which means bitbanging it with the softdevice running is going to be challenging.</p> <p>You have to use that EEPROM? Using one which works on SPI or I2C would make your life a whole lot easier.</p><div style="clear:both;"></div>
