python-r305's Introduction

python api for R305 Fingerprint module over UART.

installation

using pip

$ pip install R305

For Fedora and centos

$ dnf copr enable girish946/R305
$ dnf install python-R305

Usage

To store the fingerprint in to the module

from r305 import R305
import sys

device   = sys.argv[1]
baudrate = sys.argv[2] # the default baudrate for this module is 57600

dev = R305(device, baudrate)

def callback(data):
    x = raw_input(data)

result = dev.StoreFingerPrint(IgnoreChecksum=True, callback=callback)
print(result)

To search fingerprint in the module

from r305 import R305
import sys

device   = sys.argv[1]
baudrate = sys.argv[2] # the default baudrate for this module is 57600

dev = R305(device, baudrate)

result = dev.SearchFingerPrint()
print(result)

python-r305's Issues

Need some sample code as wiki

Hello,

I had hardware & debian operating system.

Can you provide sameple code and steps so we can utilize this lib.

Thanks in advance.

Store fingerprint on a database?

Hi, is it possible to store the fingerprint data to a MySQL or other database?

Missing Functionality for real use cases

Thanks for the good / efficient code for the R305 library.

I think this is a library with partial functionality with efficient code. For example, uploading / downloading templates from the host system is missing. As per the documentation, there is a restriction on packet length in certain commands/operations. The templates and character files are longer than limit and need to split into multiple packets. "EOP" (end of data packet) identifier has been used the in the package identifiers list in R305.py but not used. This will be required for actual usage.

Further, I am skeptical about the code in DownChar function. As per the documentation, it will only need 1 parameter of BufferId. You have made provision for PageIds as well. The examples sited have not used the DownChar function. Correct me, if this is not the case and there is some code which I have missed in DownChar. Has it been tested?

Is this applicable also with R307 fingerprint scanner?

Using with Raspberry UART

I am trying to use with raspberry pi 2 and any command the reader light turns on and it immediately shuts off. Can you tell me why?

Error trying examples

I have a error during store_finger_print.py executing:
./store_finger_print.py /dev/ttyUSB0 57600
Traceback (most recent call last):
File "./store_finger_print.py", line 12, in <module>
result = dev.SearchFingerPrint()

finger_on_sensor = self.GenImg()

File "/home/super_pypsik/work/projects/imx/python-R305-master/device.py", line 19, in getHeader
if command in instruction:
NameError: name 'instruction' is not defined

ImportError: No module named 'device'

Dear Girish,

while running the example program on windows 8.1 I get this error

Traceback (most recent call last):
  File "C:\Users\Elcot\Desktop\R305\python-R305-master\examples\store_finger_print.py", line 4, in <module>
    from r305 import R305
  File "C:\Python34\lib\site-packages\r305\__init__.py", line 4, in <module>
    from device import *
ImportError: No module named 'device'

even through I connect with R305 by using UART to USB converter

Thanks for nice work, I found error please update error in code.

def getChecksum(data):

"""
calculates the checksum of the packet.
:param data: the datapacket
Returns the list containing two bytes which are the checksum of the given
packet.
"""

frame = data[6:]
csum = sum(getIntList(frame))
_csum1 = int(csum / 256)
csum2 = csum % 256_
#print(hex(csum1), hex(csum2))
return [csum1, csum2]

can we elaborate a sqlite template storage example?
