1 # NXP PN80T/PN81A support 2 3 libese support for the PN80T series of embedded secure elements is 4 implemented using a common set of shared hardware functions and 5 communication specific behavior. 6 7 The common behavior is found in "common.h". Support for using Linux 8 spidev s in "linux\_spidev.c", and support for using a simple nq-nci 9 associated kernel driver is in "nq\_nci.c". 10 11 # Implementing a new backend 12 13 When implementing a new backend, the required header is: 14 15 #include "../include/ese/hw/nxp/pn80t/common.h" 16 17 Once included, the implementation must provide its own 18 receive and transmit libese-hw functions and a struct Pn80tPlatform, 19 defined in "../include/ese/hw/nxp/pn80t/platform.h". 20 21 Platform requires a dedicated initialize, release, wait functions as 22 well support for controlling NFC\_VEN, SVDD\_PWR\_REQ, and reset. 23 24 See the bottom of the other implementations for an example of the 25 required exports. 26 27 Any other functionality, such as libese-sysdeps, may also need to be 28 provided separately. 29
