CODE EXAMPLE
SERIAL PACKET TRANSMISSION
TEST PLAN
Decouple all components in the system and test them independently and as a whole. LCD and LEDs will be used to display system state
FINGERPRINT SENSOR
Predefined diagnostic sequence to verify proper communication and functionality. Includes enrolling and fingerprint verification.
ANDROID APP
Utilize buttons and switches on DE2 to send predefined responses to app requests
LOCKING INTERFACE
Use a switch to toggle the lock state
Additional ad-hoc and usability testing will be completed on the system as a whole
APPLICATION NOTES
Currently working on application notes for Ethernet setup and fingerprint sensor setup/API
PROJECT EXTENSIONS
- VOIP intercom
- 2-factor authentication
- Hardware based fingerprint recognition
