Responding to: ???'s previous message
Dear Lian,


I think the problem is with subroutine display. I should clr RW, setb Enable and setb RS then only "move P1, a" then clr Enable, right?


There's absolutely no problem with subroutine display. The alternative you mentioned wont improve the situations.

It seems your LCD is not intiatialised properly. add these lines at the start of your code.
Save This Code
    MOV A,#30H
    LCALL COMMAND
    MOV R3,#10
    LCALL DELAY
    MOV A,#30H
    LCALL COMMAND
    MOV R3,#10
    LCALL DELAY
    MOV A,#30H
    LCALL COMMAND

Delay souroutine:

DELAY :
    MOV R5,#0FFH
    SUBDELAY :
        PUSH 05H
        MOV R5,#0BH
        DJNZ R5,$
        POP 05H
        DJNZ R5,SUBDELAY
    DJNZ R3, DELAY
RET


regards,
Prahlad
