Hello Everybody!
I wrote a testing code for scanning rc5 protocol codes to scan philips SAA3010 remote on port P2 by connecting LEDs but it does not do any response to my hardware. i just toggle P2 by using only two ir signals from remote. The code is written below please notify my about my mistake and also help me developing appropiate code. the code is as:

MOV R0,#09
MAIN:

JB P1.0,$
JNB P1.0,$
DJNZ R0,MAIN
MOV R0,#05
CLR A

MAIN2:

call delay_900uc
MOV C,P1.0
RLC A
DJNZ R0,MAIN2
RLC A
RLC A
RLC A
CJNE A,#38,LABEL1

LABEL1:

MOV P2,0FFH
LABEL1:
CJNE A,#39,LABEL2
MOV P2,00H

LABEL2:
JMP MAIN

delay_900us:

TT0: MOV R2,#2
MOV R1,#152
TT1: DJNZ R1,TT1
DJNZ R2,TT1
NOP
RET
END
