Foreword

I thank you choose to buy offline companies Fingerprint Identification Module!

Fingerprint recognition technology is relying on the human fingerprint authentication features of

biological identification technology. As the world's most advanced and reliable fingerprint

recognition technology crystallization Fingerprint identification by the precision electro-optical

imaging system opened to fingerprint image acquisition, use complex pattern matching algorithms,

and the original registration fingerprint comparison, the judge opened identity, legal status can be

confirmed after the unlock signal output.

This module applicable to the development of fingerprint Lock, Development fingerprint wooden

cabinet and the development of fingerprint door lock systems, and other needs of the various types

of authentication products.

The user manual applicable to the company's TF - MD-M1 models of fingerprint recognition

module. The company's TF - MD-M1 models of fingerprint recognition module has been applied to

the second development of fingerprint recognition module, Module Sets fingerprint collection,

storing fingerprints, fingerprint matching and other functions, but not independence, need the PC

(PC and microprocessor) for the control and operation do. So this fingerprint module special forces

also operate various fingerprint for the second development of the instruction set.

Fingerprint Module Introduction一．Overview1、 Features

◆ Extreme high professional fingerprint recognition algorithm

(MIC) for identifying fast! 500 fingerprint identification as long

as 0.43 seconds;

◆ Super-large storage capacity, the largest storage fingerprints

3000 (three : 96, 992 and 3000);

◆ bidirectional fingerprint identification technology (patented

technology), digital fingerprint images and two-way

recognition, more safety;

◆ high recognition rate, safety, and up to : 0.00001%;

◆ 1 : N, 1:1Fingerprint Comparison (2 ways of freedom of choice);

◆ safety levels can be 10, according to their needs its own settings (applicable in different

places)

◆ advanced surface light, clear imaging, recognition speed;

◆ using high precision optical components, clear imaging;

◆ internal use advanced digital processing chip DSP (TI USA), fast processing speed!

◆ small size, circuit only : 40 * 58mm, easy integration;

◆ standard interfaces agreement to develop simple;

◆ various fingerprint identification technology fully integrated into development agreements

simple and easy to read, not understanding much knowledge will be able to fingerprint

development;

◆ advanced design of the low-frequency electromagnetic interference against external

stability;

◆ at least three times per year to update the core technology! Four years continuously

upgrading and optimization, advanced products, better!

二．Development module instructions

This mode operation process is as follows :

(1) From the start button (J10-Pin5) imported low-level pulse, wait around 100 ms complete

module from Kai;

(2) from the mouth UART input instructions, Under the directives module fingerprint

registration, delete, verification and other functions;

(3) I UART input from dormancy directive This module has received orders and entered a

state of dormancy.

Note : The development model fingerprint acquisition module, If users failure fingerprints

were waiting for the module will be permanently unable to receive other orders To now

dormant mode modules can be placed in first paragraph (1) Step reboot the system after

the implementation of paragraph (3) further.

三． Note 1, such as the use of battery power, the proposed use of alkaline batteries.

2, the system after the buzzer sounded a start, "Di-Di-Di" Sound the Alarm

Fingerprint Module Development Agreement

Apply to : the agreement applicable to the TF - MD-M1 fingerprint development module.

一． Communication

DSP module as from the equipment, the main equipment sent by the relevant orders of

their control. Command Interface : UART (Universal Asynchronous Serial Interface)

，19200bps ，an initial ，a stop place (no Parity)

Send main equipment orders and DSP module response by the data length can be divided

into two categories :

1）= 8 Byte，Data format is as follows：

Byte 1 2 3 4 5 6 7 8

Order 0xF5 CMD P1 P2 P3 0 CHK 0xF5

Response 0xF5 CMD Q1 Q2 Q3 0 CHK 0xF5

Note : CMD : command / response type

P1, P2, P3 : order parameters

Q1, Q2, Q3 : Response parameters,

Q3 used for the return operation of the effectiveness of information, this time you

can have the following values :

- 6 -

fingepint modules Manual# Define ACK_SUCCESS 0x00 / / successful operation

# define ACK_F AIL 0x01 / / operational failure

# define ACK_FULL 0x04 / / fingerprint database Man # define

# define ACK_NOUSER 0x05 / / users unnecessary

# define ACK_U SER_EXIST hex 07 / / user has existed

# define ACK_TIMEOUT 0x 08 / / Acquisition overtime

CHK : the first two bytes to the first six byte XOR value
