Sir, I am using the above circuit for my finger-print project. I am using SM-630 Module.
I have changed the port numbers according to the above circuit in your program for finger-print security system. Also, I am not using the port for ALARM. So, I have not used that port in your program.
But still the project is not working. Can you tell me whether some other changes have to be made in your program.
I have attached the changed program according to my circuit below...

What is the use of
ORG 23H ( Why 23h ??? )
What does the function SERIAL do in the above program...
Also Sir, What is the use of READ_FLASH and STORE_FLASH in your program. What does that instruct the sensor to do?
if you enable serial interrupt in your program then the microcontroller jumps to the Interrupt service Routine when it receives any data through serial port.
The ISR location is 23H for serial Interrupt.
READ_FLASH and STORE_FLASH are used to read and write the user flash memory in the finger print module.
Source code of your project
I need the source code for finger print attendance system.i would be thankful to you for this favour.
i need the source code for finger print based attendance system. EMAIL ID:firstname.lastname@example.org
Sir i cannot view the circuit. Please can u send the circuit and source code to my email : email@example.com
Why you cant see the circuit?
I think there is some problem in your browser. try changing or reinstalling it.
can you please send me the circuit for "fingerprint based attendance system using optical sensor"?and Please tell me
how can I interface sensor?
