我最近从here购买了ACR122U。 我正试图将其置于卡模拟模式,使其与在启动器模式下运行PN7150的系统通信
我已设法与设备的PN532 IC(user manual)通信;发送基本命令,例如获取状态、FW版本等
但我无法将其置于卡模拟模式。下面是我尝试使用的超级简单python脚本:
from smartcard.System import *
from smartcard import util
'''
Command Application Protocol Data Units
C-APDU Structure:
[ Class + Instruction + Param_1 + Param_2 + Data Length + Data ]
'''
# ACS Direct Transmit Header - [ Class + Instruction + Param_1 + Param_2 ] #
ACS_DIRECT_TRANSMIT = [ 0xFF, 0x00, 0x00, 0x00 ]
# PN532 COMMANDS - [ Data Length + Data ] #
PN532_CMDS = {
'GET_READER_FW_VERSION' : [ 0x02, 0xD4, 0x02 ],
'GET_READER_STATUS' : [ 0x02, 0xD4, 0x04 ],
# Enable ISO/IEC 14443-4 PICC emulation & automatic RATS #
'SET_PARAMETERS' : [ 0x03, 0xD4, 0x12, 0x30 ],
'CONFIGURE_CE_MODE' : [
0x27, # Data Length
0xD4, 0x8C, # Command header
0x05, # Mode - PICC/Passive
0x04, 0x00, # ATQA
0x12, 0x34, 0x56, # UID: Last 3 bytes
0x20, # SAK
# =====[ Unused ] ===== #
# FeliCa Params #
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
0x00, 0x00,
# ATR Bytes #
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,

]
}
def printResponseApdu(data, sw1, sw2):
data = util.toHexString(data)
status = util.toHexString([sw1, sw2])
print(f"R-APDU << Data:{data} Status:{status}")
def main():
scReaders = readers()
print("Available readers:", scReaders)
reader = scReaders[0]
print("Using:", reader)
connection = reader.createConnection()
connection.connect()
print("Connection Established!")
respData, sw1, sw2 = connection.transmit(ACS_DIRECT_TRANSMIT + PN532_CMDS['CONFIGURE_CE_MODE'])
printResponseApdu(respData, sw1, sw2)
if __name__ == "__main__":
main()
这将导致以下错误:
...
sw1 = (response[-2] + 256) % 256
IndexError: list index out of range
我假设这意味着没有收到响应,我不认为这是驱动程序问题,因为其他命令工作正常
如有任何见解,将不胜感激
