Notes
- module used-R305
- At power on, it takes about 500ms for initialization. During this period, the Module can’t accept
- commands for upper computer.
- supply -DC 3.6V-6.0V
- here only reads the fingerprint
- please enroll using sys software
- it has 3 steps to read & check finger print
- step 1-collect finger image
- step 2-To generate character filefrom image
- step 3- search finger library for for previously stored finger print
- use softuart to see the output
