MFEV710

Pegoda EV710

The contact part of the reader firmware is used to communicate with a SAM, ideally the

MIFARE SAM AV2, see Ref. 2. The contactless part performs the polling and activation

sequence according to PC/SC part 2, ISO/IEC 14443-3 and 14443-4 standards.

The polling and activation sequence can be turned off and on with the use of escape

(PC/SC part 3) commands. The polling and activation sequence is automatically disabled

if escape commands are executed that would interfere with the normal operations. The

firmware also interprets the ADPUs for MIFARE which are defined in PC/SC part 3.

The main modes of operation are being set by DIP switches which are located on the

reader. Some configuration parameters can be set with the escape commands. The

reader will store them in non-violate memory. The user will be able to reset the

configuration back to default state.

The firmware will construct the product name – which is returned by USB descriptor – to

easily identify the reader/SAM configuration. Depending on the DIP switches, there are

three possible configurations:

The user will be able to flash the board with customized or original firmware with three

methods:

For more information, please refer to Ref. 6. The implementation of the driver is described

in Ref. 9.

7.3.2 NXP Reader Library

The Reader Library is a special build of the functionality provided by the Basic Function

library. The desired functionality can be selected by the user and compiled dependent on

application requirements. On the CLRD710 the Reader library is implemented to be

executed on the Host PC. The library is designed to be portable, it can be ported to any

embedded environment if desired. As such it can be also ported to the controller of the

CLRD710.

The NXP reader library is encapsulated into Layers and Components written in ANSI C.

The library structure provides a modular way of programming and setting up the reader

interface.

For easy portability, the reader library consists of 4 layers:
