• Just learnt that the GT511C3 uses the SmackFinger 3.0 Algorithm for identification.
    Does that help in replicating the algorithm for identification/verification?

    @PaddeK any other info on the GT-521F52 shared database on a network?

  • I did not find anything about that in the datasheets. But it acts as an usb drive so there are sure ways to do this. I ordered one because i am very interested in the touch wake up feature.

    About the algorithm.. i dont think this will help. The matching of a fingerprint is not like simple string matching. You cant just let the fingerprint generate a template and then search for a match in a database. There is all kinds of magic and fairy dust involved :)

  • My GT-521F52 arrived today.. i hope i can find some time this weekend to test it.

  • can I know which are the 12 bytes you send to sensor for EnrollStart() and also for Enrollchecked().

  • Can You please help by giving me answer of which are the commands goes to sensor for 12 bytes to startEnroll() and CheckedEnroll

  • int i = 0;

                byte[] Parameter = new byte[4];
                Parameter[0] = (byte)(i & 0x000000ff);
                Parameter[1] = (byte)((i & 0x0000ff00) >> 8);
                Parameter[2] = (byte)((i & 0x00ff0000) >> 16);
                Parameter[3] = (byte)((i & 0xff000000) >> 24);
    
                // SetSpeed = new byte[] { 0x55, 0xAA, 0x01, 0x00, 0x01, 0x00, 0x00, 0x00, 0x12, 0x00, 0x13, 0x01 };
               //  Writer();
    
                SetSpeed = new byte[] { 0x55, 0xAA, 0x01, 0x00, Parameter[0], Parameter[1], Parameter[2], Parameter[3], 0x21, 0x00, 0x22, 0x01 };//checkenrolled
                Writer();
    
                SetSpeed = new byte[] { 0x55, 0xAA, 0x01, 0x00, Parameter[0], Parameter[1], Parameter[2], Parameter[3], 0x22, 0x00, 0x23, 0x01 };//enrollStart
                Writer();
    

    can you please send command of 12 bytes for enrollstart and enrollechecked

  • It looks like you're posting C code, not JS. Did you want this converted to run on Espruino, or are you actually using an Arduino? If so, you'd need to find an Arduino forum to post on.

  • I am using C# code and I want to start enroll part of FPS_GT511C1R using C# language.

  • Can u please help

  • I'm afraid we can't help - this is a forum for Espruino, which is JavaScript. I'd suggest that you contact the company you purchased it from. For instance Sparkfun sells those sensors and has a forum.
