flowtter / py-acr122u Goto Github PK

I really want it to be a library and not a code that is copied every time someone wants to use it.

Since I don't have the reader any more, I can't test the code.

Ideally, it should be on https://pypi.org/

Can you make this into a library?

Hi,

Thanks for this project ! It helps me a lot.

I face a kind of problem because I can authenticate on sector 0 and read block 1,2 and 3. But I don't manage to read others blocks frorm others sectors.
I would like to read blocks from sector 7, for instance!

Below is an extract of my code.
sector_id can vary from 0 to 15.
KEYS dict is correctly populated somewhere else!

KEY_A = 0x60
KEY_B = 0x61
KEY_LOCATION = 0x01
KEY_VALUE = KEYS[sector_id][KEY_A]

reader.load_authentication_data(KEY_LOCATION, KEY_VALUE)
reader.authentication(sector_id, KEY_A, KEY_LOCATION)

BYTES_COUNT_TO_READ = 16
print("".join(int_list_to_string_list(reader.read_binary_blocks(1, BYTES_COUNT_TO_READ)))) # This is only OK for sector 0
print("".join(int_list_to_string_list(reader.read_binary_blocks(2, BYTES_COUNT_TO_READ)))) # This is only OK for sector 0

Regards,
JD

I run "pip install py122u" but get following errors:

I'm facing a problem after writing to another block different than 0x01.
After writing to another block, i can't authenticate to previous the blocks that i have wrote data.
My code

from nfc import nfc as nfcReader

reader = nfcReader.Reader()
block_number = 0x01
custom_number = 0x20
key_location = 0x01
reader.load_authentication_data(key_location, [0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF])
reader.authentication(block_number, 0x61, key_location)

def write(position=block_number, number=custom_number, data=[0x00 for i in range(16)]):
    """ Write data to mifare tag
    Example:
        write(reader, 0x01, 0x20, [0x00 for i in range(16)])
    """

    while number >= 16:
        write_16(reader, position, 16, data)
        number -= 16
        position += 1


def write_16(r, position, number, data):
    
    r.update_binary_blocks(position, number, data)


def read(position=block_number, number=custom_number):
    """ Read data from mifare tag
    >>> read(reader, 0x01, 0x20)
    """
    print(f'block {block_number}')
    result = []
    while number >= 16:
        result.append(read_16(position, 16, reader))
        number -= 16
        position += 1
    return result


def read_16(position, number, r):
    return r.read_binary_blocks(position, number)

I was wondering, what are all the commands I can execute?

Thanks

Hello,

is it possible to read the UID from the reader in such a way that only the 8 digit hexadecimal is read like on an HID reader?

I would like to get the same values as an HID reader in order to establish the assignment via such a reader and to connect the ACR122 to the Raspberry and scan the card there for use on the Pi.

Unfortunately, I only get a 16-digit hex number.
