would like to present testing board for my brother.Heart of the system is Atmeg32 or 16 ( in this case it is atmeg32). It consist possibility of working with those displays: lcd hd44780, PCF8833 (nokia 6100/6610i), LSO20 (siemens S65/cx70), Two 7-leg LED displays LED ruler Mat
Hi, For microcontroller use AVR or PIC or anything else. I suggest AVR. For display, you can use Glcd with controller KS108/KS107/T6963 or you can use alphanumeric lcd with controller hd44780. Tahmid.
Similar unresolved thread: Better contact your vendor about the data sheet. Else as Tahmid said try comparing your module with standard Hitachi hd44780.
Hi, If you select lcd with hd44780 controller or similar, there is a command for display/cursor shift. m.
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 (...)
hey guyz i'm having a problem in programming an lcd my lcd is LM052L it has a built in LSI hd44780 and i'm using a pic16f877a i don't know what's the problem. this is my picbasic program: Device=16F877A XTAL=4 ALL_DIGITAL=true TRISC=0 lcd_DTPIN=PORTC.0 'CALL ASSIGNED ADDRESS TO PORTC.0 (...)
Dear all, I want to use a hd44780 for a hobby circuit. So I have connected with my PIC MCU in a 4-wire interface and tried to communicate with it. However I cannot display anything on the lcd. I will try to troubleshoot my design but I need to know something pretty important! I cannot understand whether the lcd has been initialized or (...)
Hey All , One simple question , I'm using hd44780 lcd 4 line , I did control the lcd , and but i couldn't understand from the websites how can i display for example "A" at the 4 lines , how can i do that please ? and if there is an c code example would be great , cuz to understand better need some example , ?? thanks alot .
First, you have to realize how the memory in an lcd is mapped. The two rows in memory aren't separate. Assuming you are using an hd44780-based display, the first row starts at like 0x00 and the second row starts at like 0x40. If you want to scroll just the second row, you need to write your own routine that will only shift the characters over from

I have a 2x16 caharacter based lcd. There is a font selection of 5x10 but it does show the characters big. What i want to do is when i want, the characters on the screen should be big and there should be only one line. I onyl want to show the numbers big. But i use both the 1 line and 2 lines modes. How can we do this. Should we use cgram for this
Hey all, From what I see there is nothing wrong with this code. It is for a hd44780 lcd, and this should initialize for 4 bit mode and then turn on the display/cursor. I get a bunch of warning for parameters without init value having a constant value of zero or something. Aren't initial values for register types always zero? [/quot
I am using MPLAB v8.10 and am trying to innitialise an lcd display and write something to it just to prove I have control pf it via the pic in 8 bit mode. It will bviously be part of a larger program eventualy and I have also written the program for A/D as shown. At the moment nothing appears on the lcd and I can see where in the program I hae gon
I am currently doing a project using hd44780 20x4 lcd display and PIC18F252 to produce a simplistic Battery monitor. At the moment all I wish to achieve is taking a voltage from a shunt amplified to around 3v and the voltage from the battery reduced to 3v and display these on the lcd display. obviously the voltage acros the shunt is (...)
Refers To hd44780 datasheet. I assume that you use Hitachi chips for lcd text controller right? Datasheet link: please look at the init time and your microcontroller datasheet for lcd timing. Happy Learning and good luck
PIC16F877A microcontroller connection with hd44780 lcd,C code for programming PIC16F877A to interface lcd
CodeVision has library functions to facilitate the handling of lcd modules built with the Hitachi hd44780 chip or equivalent, why not use it?
Equipment: PIC18F4455 MCU 4x20 lcd with hd44780 assembley language using MPLAB IDE. Helo I tray display integer value on lcd. I know, it`s only convert int to string and voila! but standard C++ convert procedures like ---> itoa doesn`t work. Any idea ? void main(void) { int k = 1234; TRISD = 0x00; //-- Port D as ou
just write "hd44780" "lcd" and "pic" on will give u a lot of information.
