#142343 - Display blank |
I have made a routine called LCD_STRING which displays message pointed by DPTR.All messages are working correctly.But this does not.
MOV P0,#0FFH ;port0 as input MOV A,P0 ;get data from other microcontroller CJNE A,#01EH,ERR ;condition check MOV P0,#00H ;port0 as output MOV DPTR,#DATMEL ;message to be displayed CALL LCD_STRING ;routine working nicely with other mseg Port0 is having 10k pull-ups.When i am using lcd 16x2 JHD 162A with contrast it flickers otherwise it works well. |
