PIC18F452 & LCD connections

[ZERS]

Hi all,

I was wondering whether I could connect a 4 bits serial LCD to the PIC18F452 using the PORTD .

the Pins allocations would be :

LCD RS --> D0 pic
LCD RW --> GND
LCD E ---> D1 PIC
LCD D4, D5, D6 D7 ---> D4, D5, D6 D7 pic

Do I have a chance that it works ?

Regards

That's not a serial LCD?.

It's just a standard LCD text module, with a parallel type connection, you can easily connect it to a single PIC port in 4 bit mode. Have a look at my PIC tutorials where I do just that! - personally I connect RW as well, this allows the LCD to run as fast as possible.

Ok thanks nigel.
The problem with yoiur tutorial is that they are writting in assembler. And I do not understand assembler. :cry:
A C-Code will help me to understand :wink:
