The finger print module can be directly connected to PC. Why do you need micro for that? You are connecting both FP module and PC to micro using UART? You have two UART?

Actually am doing project, in that am trying to collect persons finger print. next time when the same person puts his finger, information to be displayed on LCD and photograph of tht particular person should be displayed on PC. I dont have 2 UART but am using HCF4066 analogue swith to solve that problem.

You have problem with PHP code only?

Oops.. You have problem in reading UART port. Right?

Zip and post complete project files and Circuit. Mention Fosc and Compiler used. The FP module needs min baudrate of 9600 bps.
