Deya series of stand-alone fingerprint identification module is the introduction of Deya R & D and manufacturing of small size integrated fingerprint module. To SynoChip high-speed DSP processor core, combined with the company's proprietary optical fingerprint sensor, without host computer in the management of cases, with a fingerprint input, image processing, fingerprint matching, search and template storage functions such as intelligent module. Users can conduct secondary development can be embedded into a variety of end products, such as: access control, attendance, safe, car door locks and so on.

Technique: supplies:

Works fingerprint

processing consists of two processes: fingerprint logon process and the fingerprint matching process [which is divided into fingerprint matching fingerprint matching (1:1) and fingerprint search (1: N) in two ways]. Fingerprint log on, a fingerprint for each entry two times, two times the input image processing, synthetic templates stored in the module. Fingerprint matching, through the first fingerprint sensor, input fingerprint images to verify and process, and then with the module matches the fingerprint template comparison

(If the module specified in a template matching, called the fingerprint matching method, that is 1:1 approach; if matched with multiple templates, called the fingerprint search methods, namely, 1: N mode), the module is given match results (pass or fail)

Software Development

1: Make sure the module normal

Scenario  1: Give the module after power-receive modules take the initiative issued 0x5555, can be confirmed that the module is working correctly and is waiting to receive the command state.

 Scenario 2: In the uncertainty case, the module can send a Free instructions for communication handshake, received response packet, affirming that the module normally.

 2: Fingerprint login enroll fingerprint login to use instructions, there are two methods:

Method 1:

Step 1: First use of parameter 1 (ie), the user slide a finger rub received OK response to switch the next step, otherwise repeat step 1;

 Step 2: Re-use of parameter 2 (ie), the user rubbing the user fingers sliding received OK response that login is successful, otherwise repeat step 2 until successful.

Method 2:

Step 1: Direct use of parameter 2 (ie), the user slide a finger rub received responses failed to switch the next step (which should not receive the OK response, unless the position has been finger current template), if the receipt of a finger image bad (0x21, 0x22, etc.), repeat step 1;

Step 2: still use the parameter 2 (ie), the user rubbing the user fingers sliding received OK response that login is successful, otherwise repeat step 2 until successful.

Method 2:

Step 1: Direct use of parameter 2 (ie), the user slide a finger rub received responses failed to switch the next step (which should not receive the OK response, unless the position has been finger current template), if the receipt of a finger image bad (0x21, 0x22, etc.), repeat step 1;
