You failed to mention which specific language you wish to use to develop the program. I would recommend the project into two steps: 1. Develop a library of routines for the lcd which I believe is hd44780 compatible. Appnote AN587 - Interfacing PICmicro? MCUs to an lcd Module[
The following is a tutorial demoing an hd44780 compatible lcd using 4-bit interface with the 8051 family and provides source code in both Assembly and C languages: lcd interfacing with Microcontrollers tutorial Typically, black boxes/rectangles indicated an initialization
Hi all, is there anybody that can give me an example of code to control and initialize an lcd display in assembler language.
If your lcd uses KS0066 as the datasheet you have uploaded in post #7 then it is hd44780 compatible.
how ar u programmers,am having a C codes for interfacing lcd to 89C51,i ve tried to interpret each line n i ve managed only few line,then can any one help to define each line of the codes (am new in programming).......here are the codes sbit rs=P3^5; sbit rw=P3^6; sbit en=P3^7; void delay(unsigned int delay) { while(delay--); } void
sometimes if the lcd requires more power than being supplied the contrast gets out. check if your supply line volts drop when lcd is ON? pin 15 and 16 are for backlight and they have nothing to do with contast. also check if contrast pin is correctly soldered to the header?
If you using C Language, can refer here lcd hd44780. The header here.

Hi, I am working on a project to display the temperature from a thermistor on a lcd display. Here is a list of components I am using. hd44780 PIC18F4520 LM35cz I am working in assembly language and my question is how to take the 10 bit ADC result my PIC gives me in the ADRES register and display it in Fahrenheit on the lcd. I am (...)
The hd44780 chipset offers either 8-bit or 4-bit data I/O, not 16-bit. The interface and coding method is similar to utilizing the device with an 8-bit PIC. There are numerous hd44780 compatible lcd libraries available. Are you coding in C or Assembly Language? If C, what compiler are you using? BigDog
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
You need to try first if ST7066U is compatible with hd44780. Connect your lcd in 4 bit mode. The lcd library of mikroC is so easy to use.
