i bought rfpic dev kit 1 for my project, but after i got it, i realize i have no experience with assember coding. I need some help for coding part of my design.
i am trying to make romote keyless entry with some security features.
here is the flow chart
1) The reader periodically sends out a signal that
includes the Reader ID.
2) The tag receives a signal and checks the Reader
ID value received with that in memory.
3) Upon a match the tag then transmits the Tag ID,
Security Key and Security Password
4) The reader receives the Security Key, Security
Password and Tag ID.
5) The reader first checks for a valid Tag ID. If the
ID is valid it continues the verification process.
6) The reader then takes the Security Key and
generates a local copy of the Security Password.
7) The reader compares the two Security Passwords,
if a match occurs then a valid tag has been found.
It then signals the garage door to open and
temporarily disables polling.
the demo files for the rfpic reciever and transmitter are attatched.
