Hi all,

I have some problem with showing information on LCD.[2*40]
[I'll use PIC16F84A for this project becuse I have some.]
I didn't know the URL of this pdf file so I take some Pictures,
I hope it's help.

The "serout" Function in "picbasic" work clearly for serial LCDs,
but I can't find serial LCDs here.

What is pin "E" ?
How I should put data on DB0,...,DB7 ?,[ 2*4bit after eachother or 1*8bit ]
Also the connection of this moduls is synchrone or asynchrone?

I have the datasheet of LCD already ,but I can't get any idea.

thanks in advance
Mosh

Hi, Fragrance,

The LCD he has is not a serial LCD, but a standard character LCD, that he want's to interface to the PIC. This can be done in either 4- or 8-bit mode, depending on how many PIC pins you want to use.
The example in you attachment is not for serial interface either, but 4-bit parallel mode.
Your link **broken link removed** is not for a serial LCD either, but a parallel LCD in 4- or 8-bit mode.
There''s a lot of readymade 4- and 8-bit mode charater LCD drivers for PIC in both assembly, BASIC and C.
Which programming language do you use and which compiler/assembler?

Hi loving ME

here is what you think the serial lcd posted by my self is a kind of back pack which used to convert lcd module in to serial lcd for more detail see this link

https://www.seetron.com/slcds.htm

the pdf link which i give in my post is belong to HD44780 very nice pdf how to drive lcd in 4bit mode and in 8 bit mode i also working on proffessional kind of serial lcd and graphic serial lcd with one wire interface once done i will share it with friends

Just grate, I found any information I need! (maybe More !!!) :D
I'm going to work on it, Thanks.
