This is Multiple I2C LCD code. It is written using CCS C Compiler version 5.044. This si tested in Proteus and also Easypic v7 development board with 2 x 20x4 LCDs. LCDs should be hd44780 or compatible. I have used I2C LCDs and I2C LCD modules from Banggood. I will soon post mikroC PRO pic and AVR versions of the (...)
Hi everyone i'm trying to use hd44780-based Character-LCD(4line20character) . I found some material from some forums but couldn't make it. If you check my software steps i appreciate it: 1st: I designate port configurations #define RS PORTA,0 #define RW PORTA,1 #define E PORTA,2 #define LCD_DATA PORTB #def
What a union does is let the compiler know that you want to be able to access the same location in memory in more than one way. So, for a simple example, here's how I do this in my hd44780 LCD code: union { struct { unsigned bit0: 1; unsig

If you using C Language, can refer here LCD hd44780. The header here.
You can create header file, it's extension is .h. Then, in the C code, you can include the File Name.h. Ex, code for LCD hd44780, the with the header file. Beginner now, not know how the LCD operation, just use the function/header created by m
Hey guys, I need a little help displaying the time on a hd44780 lcd. Compiling on pic basic Pro. There are two of us having the same issue. Below is the code I used. The display is Time=00:00:00 Date=00:00:00 Any suggestions would be helpful, not very good at these things. I will owe you a burrito if we can get her running. (...)
If you use hitech c or CCS, drivers for a standard hd44780 compliant LCD are in the install directories of both of them, by drivers I mean sample codes. If you search the forum for "interfacing LCD with 16F877A" I think dozens of thread will come up and in many cased there will be working codes. I remember posting a working (...)
in JHD162A JHD is the Company Name/etc 162 mean 16x2 but this lcd uses the same controller hd44780
I hooked up a Hitachi hd44780 based 2x16 LCD with pic18F2420. Now on the bootup, I should see boxes in the top row (Typical for a hd44780 based LCD). But what I see is 8 boxes in top row and 8 boxes in Bottom row. Is the LCD Blown or something else is wrong? I have attached a snapshot of LCD display 53699

Hi, That code should run fine on your 690 with any parallel hd44780 compatible lcd. Although the data ends up in the lcd, there are several slightly different ways of collecting and outputting the data. The Mikro is one way, but do not spend a lot of time trying to understand what is quite a complicated routine - just use it and concentra
pic16F877A microcontroller connection with hd44780 LCD,C code for programming pic16F877A to interface LCD
Hi all, I've see that many people have trouble about LCD interfacing, I've just finish to develop a library to do all the things needed to drive a hd44780 LCD controller based display with a pic. My application is able to work with 4 bit interface (in order to save 4 pin of the microcontroller) and also isn't restricted to some pic, just (...)
Here I would like to ask some help..... For me it is the first time for interfacing hd44780 LCD with pic 16F877.... How can I study for that...... I find some webpages which discuss about hd44780 and 16F84A..... So what is the different for programming with 16F877 and 16F84A? How can I upgrade the souce code of 16F84A (...)
