GetImage from GT-511C3 Fingerprint Scanner in Arduino/Teensy

Post by maitreyamaity » Mon Jan 23, 2017 3:34 pm

Hi,

The fingerprint sensor is Fingerprint Scanner - TTL (GT-511C3) (https://www.sparkfun.com/products/11792)

The getImage function is incomplete in the given library (https://github.com/sparkfun/Fingerprint_Scanner-TTL).

The FPS device communicates with Arduino perfectly. Now, I want to get the fingerprint image directly from the FPS when I press on the scanner. I need the image to store separately on SD card. Please help me with code sample for getImage.

Thanking you

Regards
Maitreya

I am able to receive 52116 bytes for getImage function. Need help on how to reconstruct image from received data.

getImage appears to be eight bits deep (258 row x 202 col, or vice versa) - Try http://matplotlib.org/ (Python) or similar image processing S/W to plot it out.
