looking for laser data transmission sytem using 89c51

[harishwww]

hi
i am looking for 89c51 based laser data transmission system can any body help me posting links circuit diagram etc

i have circuit using pic micro if you want i can post here circuit diagram so that you can change to 8051

I am interested on the PIC one. Can you post it?

Thank you!

here is the block diagram for pic as well as for 8051

here is the circuit diagram

now you can change micro controller like 89c51 and rest of the circuit is same

here is my dummy code will this work
for tx
ORG 00H
MOV P2,#0FFH
MOV SCON,#50H
MOV TMOD,#20H
MOV TH1,#-3
SETB TR1
AGAIN : MOV A,P2
MOV SBUF,A
HERE1 : JNB TI,HERE1
CLR TI
HERE2 : JNB RI,HERE2
CLR RI
MOV A,SBUF
MOV P1,A
JMP AGAIN
END
for rx
ORG 00H
MOV P2,#0FFH
MOV SCON,#50H
MOV TMOD,#20H
MOV TH1,#-3
SETB TR1
HERE1 : JNB RI,HERE1
CLR RI
MOV A,SBUF
MOV P1,A
MOV A,P2
MOV SBUF,A
HERE2 : JNB TI,HERE2
CLR TI
JMP HERE1
END
