vs code and ProxiLAB

admin

trying SCRIPTIS but debugger is flaky so VS Code got the shot once again.

    error = ProxiLAB.Reader.ISO14443.SendTclCommand(0x00, 0x00, TxBuffer, RxBuffer)
    if (error[0]):
        print("Tcl: {0}".format(ProxiLAB.GetErrorInfo(error[0])))
        PopMsg += "Tcl: {0}".format(ProxiLAB.GetErrorInfo(error[0])) + "\n"
    else:
        print("Tcl response: " + ''.join(["0x%02X " % x for x in RxBuffer.value]))
        PopMsg +=  "Tcl response: " + ''.join(["0x%02X " % x for x in RxBuffer.value]) + "\n"

Tcl response: 0x6A 0x86

doing some #python tests GetCard SendCommand for ISO/IEC 14443 smartcards.

  • python run and trace in Quest software as well as RGPA software. disadvantage missing debugging comf
  • so moved to VS Code with python and Keolabs lib python file
  • searching for implementation file and possible dlls for c# integration
  • Poller0 PCD proximity coupling device and PICC
  • challenge is to set up full python setup outside of delivered Quest. API functions full details?
