<아두이노에서 사용하기>
<컴퓨터에서 사용하기> - ※ 컴퓨터에서 사용하기 위해서는 USB-TTL 변환 모듈(P1182)이 필요합니다.
Start up the SFGDemo software and click Open Device from the bottom left corner. Select the COM port used by the Arduino.
And press OK when done. You should see the following with a blue success message and some device statistics in the bottom corner. You can change the baud rate in the bottom left hand corner as well as the "security level" (how sensitive it is) but we suggest leaving those alone until you have everything running and you want to experiment. They should default to 57600 baud and security level 3 so set them if they're wrong
Lets enroll a new finger! Click the Preview checkbox and press the Enroll button next to it (Con Enroll means 'Continuous' enroll which you may want to do if you have many fingers to enroll). When the box comes up enter in the ID # you want to use. You can use up to 162 ID numbers.
The software will ask you to press the finger to the sensor
You can then see a preview (if you cliecked the preview checkbox) of the fingerprint
You will then have to repeat the process to get a second clean print. Use the same finger!
On success you will get a notice.
If there's a problem such as a bad print or image you'll have to do it again.
