user24287: I have an fps gt-511c1r fingerprint sensor module. I want to know whether i can run it using teensy 3.0 or above?
I have tried it successfully using arduino uno.
EDIT: I have uploaded the fps blink sketch on the teensy 3.2 successfully, but the fingerprint scanner is not responding. Here is the code:-
         #include "FPS_GT511C3.h"
         #include "SoftwareSerial.h"
     // Hardware setup - FPS connected to:  
     //   digital pin 0(arduino rx, fps tx)  
     //   digital pin 1(arduino tx, fps rx)  


     FPS_GT511C3 fps(0, 1);

     void setup()
     {
         Serial.begin(9600);
         fps.UseSerialDebug = true; 
         fps.Open();
     }


     void loop()
     {
        // FPS Blink LED Test
        fps.SetLED(true);
         delay(1000);
         fps.SetLED(false);
         delay(1000);
     } 

connected fps tx to teensy rx(pin 0),
          fps rx to teensy tx(pin 1),
          fps vcc to 3.3v teensy,
          fps gnd to teensy gnd.  

user4143: The GT-511C1R is a 5V device. The Teensy 3.0 is a 3.3V device. You will require some level shifting as you would with any 3.3V Arduino connecting to a 5V device.
Besides that, yes, the Teensy 3.0 is more than capable of working with the fingerprint scanner. Will the software work? Most likely, but only trying it will confirm that.
