All the relevant PN5180 registers can be modified and fine-tuned using the NFC Cockpit.
After successful register optimization, the found settings can be stored in the PN5180
EEPROM.
The NFC Cockpit also allows a dump of the complete user EEPROM content into an
XML file. This file then can be loaded again into the EEPROM. That allows to manage
and exchange different user or antenna configurations. In addition, the register settings
found to work well using the NFC Cockpit, can be used during user code development as
well.
As soon as the register settings for the targeted protocols and data rates are defined, the
NFC Reader Library including the HAL can be used to start the development of the user
application. Examples illustrate the usage of the library for typical use cases.
The source code examples of the NFC Reader Library can be used to develop an own
application directly on the LPC1769 (see [5]), or can serve as a starting point for porting
the NFC Library to any other microcontroller platform.
2 Hardware
The PNEV5180B V2.2, as shown in Fig 1, provides a lot of test functions which might
not be used for the typical hardware and software evaluation. It can be used as a simple
standard reader without modification, it can be used to define and optimize the analog
settings for any connected antenna or it can be used to develop and modify any RFID
and NFC application based on the NFC Reader Library.
2.1 Hardware introduction
The PN5180 is supplied with a supply voltage, which can be chosen between: internal
and external supply. For the internal supply either 5V or 3.3V can be used. The external
power supply can be an AC or DC supply (polarity does not matter) with at least 7.5V,
since the board provide a rectifier and LDO to supply the circuit with 5V and 3.3V.
The PN5180 is connected to an NXP LPC1769 µC via SPI. A specific firmware on the
LPC1769 allows to use the PNEV5180B in together with the NFC Cockpit.
The connection to the PC is done via USB. Both USB Mini and USB Micro connectors
are supported.
Another connection option allows to connect a LPC-LINK2 board the PN5180B by means
of a debug cable. This allows the development of custom software or the execution of the
NFC Reader Library code including samples.
In case a different host microcontroller shall be used, the SPI interface is available for
connection to an external host (the on board LPC1769 is not used in this case).
