Jan 24, 2016. I'm probably missing something easy but i'm part way through building a fingerprint controlled device and can't get the SFG Demo software to open or install. I've set up my Arduino Uno and the fingerprint sensor so am ready to enroll my fingerprints but need SFG to do this. I've unzipped the download but.

While biometrics and fingerprint identification has been existing for well over 100 years in some basic form, it is the growth of maker community that made modules like R305 and SM630 so popular. R305 and S630 are common modules used for fingerprint scanners, with the aid of a powerful DSP in its core. Basically both of these modules work the same way, we can communicate with them using a packet of hex codes in a specific format.

However, the commands for operation can vary from module to module, for which we should have its datasheet. Well, for now we have the R305 here, just tested it with the products demo software from SFG. Though these have no good English documentation, SFG has done a real good work with the demo software (except the bad UI ). Lets get started.

Pinout The first 4 pins are for serial communication with default baudrate of 57600. User may set the baud rate in 9600 -115200 bps.

Pins 5 – 8 are for USB communication. Connection Diagram Connect the fingerprint reader to the computer via USB-serial converter. The connection diagram shown here uses the. Another good option is the for the USB to serial conversion. You can find variety of converters.

If you use USB data from reader, you need not use this converter. Once all the necessary connections are made, connect the setup to PC using.

The cable is used both for powering the system and for communication between the system and PC. When powered on, it usually takes about 500ms for initialization. During this period, the module can’t accept commands. The red LED on the scanner pad blinks during this time, this indicates that the sensor is working. Module address Each module has an identifying address. When communicating another system, each instruction/data is transferred in data package form, which contains the device address. Module responds only to data package whose address value is the same with its identifying address.

The address length is 4 bytes, and its default factory value is 0xFFFFFFFF. User may modify the address via instruction. The new modified address remains at power off. Communication Protocol When communicating, the transferring of command/data/result are all in a specific data package format. The data package format for communication is shown below: Thus a data package transferred to or from the module will include a Header, Address, Package Identifier, Package Length, Package Content, Checksum. Consider an example here: EF 01 FF FF FF FF 01 00 03 01 00 05 The example shown above asks the module to collect the finger image.

For more details on the data package contents see the table below: New user enroll with software: We found a compatible software for the module, which made it really easy to add, search fingerprints. Download link for the software is provided at the bottom of this page, below we have the step by step procedure for adding a new fingerprint using this software: 1. Start up the software 2. Click Open Device (in the bottom left corner). A new window opens up. Select the COM port used by the USB – serial converter (You can get the COM port from the device manager) and press OK when done.

Note: Our attempts ran into trouble when the COM port assigned was >10. Changing it to something.

Hi, I have problems with using this fingerprint reader. First, I’ve soldered the USB connections as the documentation says, connected to a laptop and nothing happened. The red led stays dark, the computer cannot see any device. Second I soldered the serial connector to a FTDI usb to serial board. When I connect it to the computer the red led blinks on the reader and I can connect to it with the demo program. When I click on Capture or Enroll then after the “Image transfering” message always get a “Create specified file error”.

If there is any connection error or default address/password has been modified,it will pop up this error. For setting address you can use the SetAdder(Set Module address) instruction. Set Module address SetAdder Command (or instruction) package format: 0xEF01 Xxxx 01H 07H 15H xxxx sum Header(0xEF01),original Module address(Xxxx),Package identifier(01H),Package length (07H),instruction code (15H ),New Module address(xxxx), Checksum(sum) Acknowledge package format: 0xEF01 Xxxx 07H 07H xxH sum Header(0xEF01),New Module address(Xxxx),Package identifier(07H),Package length (07H),confirmation code (xxH ), Checksum(sum) Note: Confirmation code=00H: address setting complete; Confirmation code=01H: error when receiving package.

ABSTRACT Fingerprint matching has been successfully used by law enforcement for more than a century. The technology is now finding lot of other applications such as identity management and access control.

In this context, an automated fingerprint recognition system and identification of key challenges are described along with the research opportunities. The description is like a product design in this report implementing RTOS (Real time operating system) under the domain of embedded system. Fingerprint Recognition is a widely popular but a complex pattern recognition problem. It is very difficult to design accurate algorithms capable of extracting salient features and matching them in a robust way.

In this paper, we have come with a novel approach to simplify the existing problems with a proper Embedded System Design. You have selected one or more posts to quote.
