Anyone still using the fingerprint scanner? I have the http://www.robotshop.com/ca/en/fingerprint-scanner-5v-ttl.html
The datasheet http://www.robotshop.com/media/files/pdf/datasheet-sen-11792.pdf suggests that
Red 3.3V (Max 6V)
Black =GDN
Yellow = RX
Green TX
As per normal I have a few issues. I have loaded both fingerprint.ino and enroll.ino from the library ADAFRUIT_FINGERPRINT, using the "Use this Example" neither compile, can't seem to find the .h file. I can get around this by loading both the .cpp and .h files onto the particle.ide.
Seems to have a password issue. With the .h and .cpp files in the particle IDE .
Adafruit_Fingerprint/Adafruit_Fingerprint.cpp:56:36: warning: narrowing conversion of '(((Adafruit_Fingerprint*)this)->Adafruit_Fingerprint::thePassword >> 24)' from 'uint32_t {aka long unsigned int}' to 'uint8_t {aka unsigned char}' inside { } [-Wnarrowing]
(thePassword >> 24), (thePassword >> 16),
Looks like the code wants some kind of a password, but I got nothing with the scanner about this. Any suggestions.
If anyone is curious other than @peekay123. Here are the error messaqges straight from loading the files from the library with the "Use This example".
enroll.ino say

This looks like an error in Adafruit_Fingerprint library. Would you like to create an issue on GitHub to let the author know?
