+# nxpnfc_android_nougat
+
+This repository contains the files allowing to patch 8.1.0 Oreo version of AOSP source in order to add support for PN7150 NXP-NCI NFC controller to an Android based system.
+It only applies to Oreo Android versions (for other releases see appropriate repository: https://wiki.codeaurora.org/xwiki/bin/NCI+NFC+Controller+SW+resources/).
+
+Information about NXP NFC Controller can be found on [NXP website](http://www.nxp.com/products/identification_and_security/nfc_and_reader_ics/nfc_controller_solutions/#overview).
+
+Further details about the stack and integration guidelines [here](https://www.nxp.com/docs/en/application-note/AN11690.pdf).
+
+Any question ? see [NXP Community](https://community.nxp.com/community/identification-security/nfc/content).
