It's working like a charm with the windows software + blank sketch but as soon as I upload the fingerprint sketch...
Did you change the wiring for the fingerprint sketch? It is not the same as for the blank sketch.

Thanks a lot for your support.

Yes i do change the wiring.

I seems like the packets are corrupted and missing. with FINGERPRINT_DEBUG during the verifyPassword function

Code: Select all

---> 0xEF 0x1 0xFF 0xFF 0xFF 0xFF 0x1 0x0 0x7 0x13 0x0 0x0 0x0 0x0 0x0 0x1B
<---  0xEF 0x81 0xFF 0xFF 0xFF 0x87 0x80 0x3 0xC0
As far as I can see the 0x81 should have been 0x1 and one 0xFF is missing from the address block

Timing or length or parity pb ?

It is possible. Verify that the settings in SFGDemo match what you are using in your Arduino sketch.

The SFGDemo software link is on the product page: http://www.adafruit.com/datasheets/SFGDemoV2.0.rar
You need to download, install and run it. It will not pop-up automagically.
Then i try the second step wich is to make it work with the arduino I try to enroll and try to download the sketch but it keeps showing me errors.!!!?
What errors do you see? Post the exact text of the error messages.

@nitheesh - the Sfgdemo software works with the ZFM-20 fingerprint sensor we sell here in the store. The R305 is a different sensor and may not work with this software.

Finger print sensor

Post by looma880 »

Hi ,
please i want help
i bought a ( Finger print sensor ) from your company and i downloaded all
libraries ,all codes and the video from the official site of adafruit and it
doesn't work
Now, my situation is very critical and i want a sulotion so i want to the
working library of finger print sensor and the codes for (Enroll , finger
print) coz i need it in my graduation project

I connected all the wires in the right way in the ( Arduino UNO ) board like
the video and i think that my problem in the codes
when i connected the finger print sensor in the board and uploaded the code
it didn't turn on ...
please tell me the perfect method to make this work (wires connection , the right code , if i need install the SFGDemo or not , how i know the problem )
please tell me all steps carefuly ....

thanks in regard ...

Hi,
I received the fingeprint sensor 2 days ago, but I can't get it working.
I tried with the SFG software (with the relative wiring in ports 0 and 1) and it works, but when I try to upload the "figerprint" sketch and start serial monitor I get " Did not find fingerprint sensor :( "
I changed the wiring with green in 2 and white in 3, but also 3-4, 4-5, and it doesn't work.
I tried also running arduino IDE as administrator, but nothing happened.
I'm using arduino REV3 and windows 7 x64
I connected sensor's wires to a breadboard, and the wired breadboard to each port, so I can exclude any wiring-related issue.
What can I do?
Thanks very much

(i'm from Italy, so excuse me for my bad english)

Hello. I got your sensors of fingerprints. Sensors work through the SVG Demo program. But after filling of the enroll program and connection of Arduino Uno through USB on the monitor the message: "Didn't find fingerprint sensor :(" help to solve this problem. Conducting is checked.

Hi. I recently purchased a fingerprint sensor and have only had mild success so far. I have managed to enroll my prints using the SFGDemo software on my windows 7 64bit computer. it was a challange ang i had to run the SFG program as administrator and solder my connections in order for it to work. I have still never been able to enroll through the arduino directly. It always gives the "did not find fingerprint sensor :(" message. i have tried several ports and follows the adafruit fingerprint youtube video. Attached is a picture of my wiring. I use a duemilanove with ATmega328 board. I am attempting to use the scanner for a fingerprint lock with a servo. Even with the fingerprints enrolled I still get the same message using that sketch. Any idea why my arduino isnt finding the scanner? My problem is very similar to the post form akylle.

What kind of board is that? Please show us the actual connections to the sensor.

Thanks for the quick response! Here is a pic with sensor included. The board is an elecrow. In the arduino sketch uploader I select board Duemilanove w/ ATmega328. It works with all other sketches so far. I have this same error when I plug the sensor up to my uno though. I would prefer for it to work with this board so I can use my uno for other projects.

What baud rate were you using when you ran it from the SFG program? Make sure that your enroll sketch is using the same baud rate.
