[51] Fingerprint scanner (R305) interfacing with 8051 microcontroller

[Raj_07]

Hi, i am doing project on R305 fingerprint scanner with 8051 microcontroller.
I read r305 datasheet then follow the instructions. i am done initial step..

--> send hex values (refer datasheet) EF01FFFFFFFF010003010005
--> scanner also acknowledgemen EF01FFFFFFFF07000302000C

My first problem was how to read hex values and how to check corresponding bis value in UART.

Please help me.. last one week i am doing this but not solution find it.

when you read the uart SBUF of 8051 you get the byte.
