Requirements
Usage
Userland USB Gadget implementation of CCID/ICCD class.
Implements an N-slots USB virtual IC card reader.
Requirements
Linux >= 4.9 for CCID class support
python3 (tested with 3.8 and 3.9)
python dependencies listed in setup.py
Usage
In a nutshell:
import f_ccid
with f_ccid.ICCDFunction(path, slot_count=1) as ccid:
ccid.slot_list[0].insert(card)
ccid.processEventsForever()
(but check out functionfs.gadget to setup configfs for you, and provide the
path argument above)
This module does not provide any card implementation.
The expected card API is:
card.clearVolatiles() -> None
Called when virtual power is cut to the card, which means it must flush its
volatile state.
card.getATR() -> bytearray
Called when the host tells the reader to power the card. This must return the
Answer To Reset bytestring for this card. Note that the answer must be mutable:
although it will not be altered by the reader, it will be passed on to C code
which technically could mutate it.
card.runAPDU(: bytearray) -> bytearray
Called when the host requests an Application Protocol Data Unit to be executed
by the card. The returned value must contain any response, followed by any
status bytes. Only entire APDUs are sent to the card (assembly is done by the
reader).
