at89s52 interfacing
Hi all,
i am doing a project which needs to control the text LCD with AT89S52. i got scuuess in initializing the LCD by connecting the 8 data pin to port 0 without using external pull-up resistor. However, when i try to connect to port 1 instead and make appropritate changes in programme, it can;t work.
can anyone explain the reason of failure?
Thanks!
