pyDlpRfid2 is a fork from PyRFIDGeek that drive DLP-RFID2 module (TRF7970A chipset) to read/write EEPROM-RFID M24LR64E-R.

Install

pyDlpRfid2 is a standard distutil package, to install it simply clone this repository :

$ git clone https://github.com/Martoni/pydlprfid2.git
$ cd pydlprfid2/

Then install it with pip :

$ python -m pip install -e .

shell commands

The distribution contain a binary script named pdr2 that can be used as standard shell command:

$ pdr2 -h
Usages:
pdr2 [options]
-h, --help               print this help
-v, --verbose            print more messages
-d, --devtty=filename    uart dev name path
-p, --protocol=PROTOCOL  default ISO15693
-l, --listtag            list tag present
-u, --uid=UID            give UID to access
-r, --read=OFFSET        read one block (hex)
-m, --readmultiple=NBR:OFFSET
                         read multiple blocks (hex:hex)
-M, --writemultiple=OFFSET:[DATA0,DATA1,...]
                         write multiple blocks (hex)
-g, --getsysinfo         read eeprom info
-t, --test               launch debug test code
-w, --writesingle=OFFSET:DATA
                         write data in one block

A second binary come with this package to convert BusPirate to a standard USB-UART adapter. If you are using buspirate (v4) with your DLP-RFID2 module, you will have to launch this command before:

$  bp2bridge -d/dev/ttyACM0
/dev/ttyACM0 is now configured as standard tty uart (115200)

List tag

To list tag present, use -l option :

$ pdr2 -d/dev/ttyACM0 -l
Initilize the DLP

EEPROM access

Reading

• read block 1 of eeprom with uid E0025E167B532A87 :

    $ pdr2 -d/dev/ttyACM0 -r1 -uE0025E167B532A87
    Initilize the DLP
    Block 0x01 : 012345

• read 4 block from 0 with uid E0025E167B532A87 :

    $ pdr2 -d/dev/ttyACM0 -m4:0 -uE0025E167B532A87
    Initilize the DLP
    Block 0x0000 to 0x0003 : FFFFFFFF01234567FFFFFFFFFFFFFFFF

Writing

• write blocks 1 of eeprom with uid E0025E167B532A87 :

    $ pdr2 -d/dev/ttyACM0 -w2:76543210 -uE0025E167B532A87
    Initilize the DLP
    76543210 written at 2

• write 4 blocks begin at block 4 with uid E0025E167B532A87 :

    $ pdr2 -d/dev/ttyACM0 -M0:"00000000, 11111111, 22222222, AAAAAAAA, EEEEEEEE" -uE0025E167B532A87
    Initilize the DLP
    Block 0x0000 to 0x0004 written
