class ATR:

Constructor: ATR(atr)

View In Hierarchy

ATR class.

Method __checksyncbyte__ Check validity of TS.
Method __init__ Construct a new atr from atr.
Method __initInstance__ Parse ATR and initialize members:
Method __str__ Returns a string representation of the ATR as a stream of bytes.
Method dump Dump the details of an ATR.
Method getBitRateFactor Return bit rate factor.
Method getChecksum Return the checksum of the ATR. Checksum is mandatory only for T=1.
Method getClockRateConversion Return clock rate conversion.
Method getGuardTime Return extra guard time.
Method getHistoricalBytes Return historical bytes.
Method getHistoricalBytesCount Return count of historical bytes.
Method getInterfaceBytesCount Return count of interface bytes.
Method getProgrammingCurrent Return maximum programming current.
Method getProgrammingVoltage Return programming voltage.
Method getSupportedProtocols Returns a dictionary of supported protocols.
Method getTA1 Return TA1 byte.
Method getTB1 Return TB1 byte.
Method getTC1 Return TC1 byte.
Method getTD1 Return TD1 byte.
Method isT0Supported Return True if T=0 is supported.
Method isT15Supported Return True if T=15 is supported.
Method isT1Supported Return True if T=1 is supported.

def __checksyncbyte__(self):

Check validity of TS.

def __init__(self, atr):

Construct a new atr from atr.

def __initInstance__(self):

Parse ATR and initialize members:

  • TS: initial character
  • T0: format character
  • TA[n], TB[n], TC[n], TD[n], for n=0,1,...: protocol parameters
Note

protocol parameters indices start at 0, e.g. TA[0], TA[1] correspond to the ISO standard TA1, TA2 parameters

  • historicalBytes: the ATR T1, T2, ..., TK historical bytes
  • TCK: checksum byte (only for protocols different from T=0)
  • FI: clock rate conversion factor
  • DI: voltage adjustment factor
  • PI1: programming voltage factor
  • II: maximum programming current factor
  • N: extra guard time
def __str__(self):

Returns a string representation of the ATR as a stream of bytes.

def dump(self):

Dump the details of an ATR.

def getBitRateFactor(self):

Return bit rate factor.

def getChecksum(self):

def isT0Supported(self):

Return True if T=0 is supported.

def isT15Supported(self):

Return True if T=15 is supported.

def isT1Supported(self):

Return True if T=1 is supported.
