#190945 - The subroutine doesn't work |
Hi all !
I realized and tested with Isis that, the given subrotine, called " WAIT_LCD" in the " Introduction to LCD Programmming" article, doesn't work. The working subroutine should be like this : WAIT_LCD: SETB RW ;It's a read command SETB EN MOV P3,#0FFh ;Set all pins to FF initially MOV A,P3 ;Read the return value CLR EN JB ACC.7,WAIT_LCD ;If bit 7 high, LCD still busy CLR RW ;Turn off RW for future commands RET Best Regards!! |
