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 (...)
Hi, I am trying to get an lcd hd44780 lcd working with an ATmega324P. The lcd works fine in the self-test mode (pin 3 grounded) but I get nothing when trying to send data via the MCU. I am using the lcd code sample that comes with avr-libc and 4-bit communication via port C. Any suggestions of what (...)
Can i somehow use a character lcd to display graphics? Like i wanna change font of lcd or Display an emoticon?
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 to 16F877? Best (...)
Most of the lcds use the standard hd44780 chip or the KS which is also hd44780 compliant chip. Here is a zip file that might help you in interfacing the lcd with MCU.
I have used this page several times and it should help with building an interface library for a hd44780 lcd. Sadly, I do not know any examples for that particular compiler...but there are many out there for other PIC compilers which should be helpful even if it isn't a direct copy & paste.
Pelase! I need a source code in C (to build with SDCC in lnux) to make a PIC16F628 use a 44780 lcd. I found only in assembler :cry: Tanks!!!
Hello All, Anyone happen to know the make and model of the lcd display for the Spartan3A DDR2 Dev Kit? I require the datasheet, but unfortunately I wasn't able to find anything in the Xilinx documenntation.
you have use #define within the main routine dont do this define all things at the very top of the code any variables not local to just the main routine need to go here also attached is an lcd driver before use you need to #include this class then in main you just need to call the init branch in the class void lcd_INITIALMODE
hello everyone, :D merry Xmas!:D I have some question about lcd hd44780 of hitachi ! which is difference between V1-V2..V5(pin 26->30) and VCC pin (in datasheet below they say that they are also power supply)! and which is the usage of COM1->COM16 pin!
Hi, I think this is a hardware limitation. Standard 2x16 lcd display usally use hd44780 chip, which CGRAM can only store 8 (5x8 format) or 4 (5x10 foramt) user defined character. To display a text composed with all the 29 specific character, you will have to send each specific character on the CGRAM. Then display it (the specific charater is s

hello, all my friends I'm using lcd hd44780 I want to build myself lcd character by using the character box but I don't know much detail about it.How do I build them? plz tell me more detail about that problem.And send me some Example. thank you
HI, i want lcd hd44780 8-bit MODE source code in c-language. I am using HIGH TECH PIC-Clite compiler for PIC16F877. So plz if anyone have this code then send it to me. Thanx n advance
hi guys i am using a 5282 coldfire processor and trying to interface a 2x8 lcd with hd44780 controller. i am trying to use the general purpose io pins from 5282 processor and have written a simple code just to initialize the display but it is not getting initialized. i am able to write the data on the gpio successfully. I tested it by putting l
Greetings. I changed the old hd44780 16x1 display for this one because it has backlight and is 16x2 BUT it has a S6A0069 controller chip. I researched very much on the net and found they say S6A0069 lcds displays are compatible with hd44780, so I connected it with the same pinout. When I turn on the circuit lcd (...)

Hi, i am interfacing the VARITRONIX 20X4 lcd the part number is MDLS20464-LV-LED04 with 8051 based controller i previously interfaced hd44780 20x4lcd no problem but when i am using same program with this lcd it is not working i think program is working fine there is any problem in Contrast voltage at pin 3 i (...)
this code is using in the LCM driver by 44780 ,if your lcd is not driver by hd44780,then you should modify some code,refer to the datasheet of your LCM. the Initial code is very important,and maybe it is different if your different typr lcd.
Hi, I'm working on lcd hd44780. To display text or value is no problem but I want to display moving message on it. I don't understand it. Could anyone help me, pls! I'll be very thanksful! (fan of C language) :D
