yes ok,

i'm writing this code for the servo:
ORG 0000H

MOV TMOD,#10H
MOV P0,#0FFH


REPEAT:

MOV TH1,#0F5H
MOV TL1,#0DDH
SETB TR1
SETB P1.4
BACK: JNB TF1,BACK
CLR TR1
CLR TF1



MOV TH1,#8FH
MOV TL1,#7FH
SETB TR1
CLR P1.4
BACK_1: JNB TF1,BACK_1
CLR TR1
CLR TF1

SJMP REPEAT
END

but the servo is still rotating 180 degrees. If I want the servo to rotate , for example 45 degrees, what should I do?

thanks,
jesmond.
