Fingerprint developing module
|
- ADEL fingerprint module consists of high performance digital signal processor which called DSP board , large capacity FLASH and 300,000 pixels colourful CMOS .
- ADEL entirely possess of independent copyright of the arithmetic of fingerprint identification.
- It is not necessary for the manufacturer of fingerprint terminal products to know about the specific theory of the fingerprint disposing and identifying. Once they apply the module to their products , the module will complete the relative function of fingerprint enrolling, disposing and contrasting by the communication port sending instructions, which would notably shorten the time of developing fingerprint products for the manufacturer.
- The user is provided with demo software.

The serial wire which is provided for user to debugging module by PC. The user could do demonstrating according to the demo software which ADEL offer. Every function is as follows:
- connected with PC keyboard interface , putting out power supply;
- connected with PC serial port;
- connected with keyboard wire , supplying power for keyboard;
- connected with port 232 of DSP board , the colourful wire connected with pin 1.

Fingerprint module demo softwareDSP board , fingerprint reader and PC are connected by serial data wire . The module independently do the function as fingerprint enrolling , image disposing , characteristic getting , templet building , templet storing and fingerprint matching or finerprint searching , and so on. |

Module instructions:
| |
DetectFinger: Detect if there is one finger on the sensor |
| |
GetImage: Read image from the sensor |
| |
GenTemplet: Get the characteristic of fingerprint according to the original image |
| |
MatchTwoTemplet: preciously match the two characteristic files
... |
Definition of confirming code:
00h: Finish successfully
01h: Error during the data package receiving
02h: No finger on the sensor
03h: Fail to input fingerprint image

The host set up the parameter of module by the instruction SysConfigure.There is one parameter table , which define various parameter of the module.Yet the instruction SysConfigure could change each item .
......
After host could enter sleeping status by sleeping instruction Sleep, the power consumption would maintain below 5uA. Because the module is in deep low power consumption by cutting off power , it will refuse to receive any instruction from host ,only the pin WakeUp could wake up the module.
