Much progress has been made since last week as far as the fingerprint scanner. Last Tuesday in lab, it was discovered that the assumed wiring of the scanner was incorrect. The correct wiring has been determined. Much time was spent attempting to get UART communication working between the fingerprint scanner and the PIC. It was discovered that the wire which is being used to connect the fingerprint scanner to the breadboard was preventing transmission from the fingerprint scanner to the pic from being received. When held in the right orientation, the fingerprint scanner was able to receive the 12 byte command packet and return a 12 byte response packet as well as a data packet when necessary. I was able to implement both an open command as well as turn on the blue LED in the fingerprint scanner. Now that the communication protocol has been worked out, I will code up a library of functions for the fingerprint scanner to perform the designated functionality as well as find a better way to connect the wires on the fingerprint scanner in order to prevent the PIC from missing transmissions. The fingerprint scanner will be combined with the SD card reader which will be able to play different tones based on the person who rings the doorbell.
