Please post a picture showing your connections.
Also, please post the output from Serial Monitor

sfizi you can start by posting some pictures of your setup, an explanation of the exact problem, what you have done to try and fix it and the code you are running and what happens when you run it.

sfizi,

First, use the code Enroll. Later, the code Verify...

The digital sensor print only turns on the light, when checking or registering.

We're going to try to check this out and see what changed! please hold on for any updates :)

[adafruit2]

OK hi everyone - I just grabbed one of the latest version of the sensor and verified it reports as "PG0305" (its actually just a firmware update) but it works just fine with our code, a Windows computer, IDE V1.05 and an UNO

There could be some other change...but we need more info!
1st up, open the Adafruit_Fingerprint.h file INSIDE the library folder.. find this line
//#define FINGERPRINT_DEBUG
and remove the //
Then saev the file, recompile and reupload "fingerprint" demo sketch
post the output, should be something like..

Code: Select all

fingertest
---> 0xEF 0x1 0xFF 0xFF 0xFF 0xFF 0x1 0x0 0x7 0x13 0x0 0x0 0x0 0x0 0x0 0x1B
<---  0xEF 0x1 0xFF 0xFF 0xFF 0xFF 0x7 0x0 0x3 0x0 0x0 0xA
Found fingerprint sensor!

Then also post exactly what IDE version you're using, the computer operating system (mac os X 10.7, Windows XP SP2, Ubuntu 14, etc!) and what Arduino you're using.

THANKS!!!!

I am currently on vacation and away from my computer and can't run the arduino code but I was using arduino ide version 1.5.7 with an arduino BANNED but i also tried it with an uno and a mega 2560. my computer os is windows 7 professional 64 bit.
thanks for your help,
Conor Walsh.

[adafruit2]

OK, if you can try the Mega or an UNO for the output thats ideal! thx!

[cwalsh]

ok I will try that when I return from vacation next Monday. I will be in touch with you then.
Thanks for your help thus far,
Conor Walsh

Thank you, I just followed your advise (probably it was the 1.5 IDE the bad) and now it seems to works great with the fingerprint sketch, I can enroll the fingerprint via SFGdemo, but the enroll sketch doesn't work on my PG0305.

I uncommented the debug line and if i put on arduino the fingerprint sketch i have the same "answer" from the console that you have, but with the enroll sketch after he ask me to send a no. for ID the console doesn't give me any answer and furthermore the sensor seems completly switch off without any blink.

@sfizi
Can you post the exact output you get?
Also, what operating system are you using?

[sfizi]

Excuse me for the late answer I was travelling.

Type in the ID # you want to save this finger as...


this the output if I send a number example 1 I just had no answer

[adafruit_support_rick]

Are you pressing the 'Send' button on the Serial Monitor?

[sfizi]

yes, of course. In fact the number "disappear".

[adafruit_support_rick]

I don't know what to say. The fingerprint sensor seems to be working. The problem appears to be with the communications between serial monitor and the Arduino itself. If the Arduino was receiving the number you send, it would print out a message, "Enrolling ID # n"

Hello,

Wondering if I can use the github library you have provided to code on Linux - ubuntu. I am getting into many errors on this,
