As you haven't stated what lcd device you have, here is a link to "Display devices in C" (8051-family): Regards, IanP
Santosh, Due to 8x8 Keyboard to be not an usual configuration, I can sugest you take some example code project with 4x4 + lcd and extend it. +++
Below is a link to a microcontroller based clock: Although it is based on the AT892051 the hardware + software are 8051-compatibile .. And here is a link on how to interface a lcd display:
hello everyone can you plzzz me out i need to interface lcd n 4*4 matrix keypad with 8051 so that wat ever is the interupt on INT0 or INT1 pin of 8051 is been measured and displayed on lcd n whatever is the changes to be made in other device connected to 8051 in my case (...)
First please specify which lcd and its datasheet. then only we can identify the memory banks and its initialization procedure.
Hi, I need your piece of advice. I am kind of novice to programming C. I am trying to create a Generic lcd_printf function, that can print decimals, string, characters. The following is the code i am trying #include // declaration void lcd_printf (const char *,...); //definition void lcd_printf(const ch
Typically in the C language character strings are terminated with a NULL (\0) which has a byte value of 0x00. The pointer to type char s, which is initialized to the first character of the character string, is first dereferenced using the * operator, then checked by the while loop to ensure it is not the
Hello, Try to add a big delay before the lcd_ini(); 100mS or more.. lcd need some time after power be ready for ...
There is Chess program with all sources and schematic in Proteus ( ) for differrent microcontrollers (8051, AVR, PIC). It uses connected graphic 256x256 dots lcd to display board.
You can see in many lcd interface with 8051 here.
Hi, You can see some source code "C" in web: Graphic lcd with AVR, lcd files for 2 lines,Graphic lcd with 8051,connect lcd in 4 bit mode, and more... Best Regard.
I don't really know any stores to order components from, but I did interface a 2 line - 8 character lcd to an 8051 controller using an 8255 I/O interface (I was using external memory so I didn't have much ports left) I remember that I found the conection and the interfacing program written in one of those books I had. (...)
Hi, Here is a lcd library you can use. It was written for K*il, but I assume it's not much of a deal to adapt it to your needs. First, you have to configure the resources you use for the lcd. This is done from the #defines in the header file. Than, call lcd_init() and the lcd is ready to go. It's not recommended that (...)
Dear All, I would like to make a project which needs a graphical lcd with touch screen function. Besides, i will try to use 8051 to control the operation of lcd and touch screen as well. Can anyone help to post some websites about.... 1. Where can i find this module? 2. How much for it? 3. How to (...)
hi! i m using lcd 2x16. i wanna ask why i only got dark block on the first row and nothing on the second row? what is actually the problem
I am using LM032L with 89C55 microcontroller. I have to interface the lcd without using any of the i/o ports of the 89C55. I have to interface the lcd at a memory address (say F000). I am facing a problem in generating the Enable, R/W, signals of the lcd. I connected (...)
hi! wish to know which header files are to be used for lcd interfacing. details of .c files to be implemented . how to write headers as per our requirement???
If I understand your task correctly, you intend to write on a PC keyboard, transmit data via serial port to 89C51 and display it in real time on an lcd .. If that’s the case, start with Hyperterminal at the PC side and short serial port interrupt subroutine at the 8051 end, read ASCII characters that are transmitted by the PC, convert (...)
What information you need exactly? I can see that, you just checked IO status to display a character on lcd. But you may see lot many characters on display for a single key press.
plz help me out and tell me how this can be done..........
A text editor Project: I want it to read ASCII text (7 bit)from an general EEPROM of I?C bus. I'll be plugging a 24C08 with preloaded text, and it will read/write the text there. Then the MCU will simply transfer the text to a 2x16 (serial) lcd (that one we use mostly). I have a 8051 MCU P80C31 and also a 8052 MCU SM8952A. Which one can (...)
Use Bit font creator pro 2.3 or lcd font maker tool to create hex file from your image. Then Load it into controller Then follow Printer Command
I have designed and written some code to display the recievers output on lcd but not getting the required output can anyone help me #include sbit rs = P1^1; sbit en = P1^2; sbit inter= P3^5; void time_delay(void); void convertanddisplay(unsigned char value); void lcd_init(void); void lcd_string(unsigned char *str); (...)
For driving motor you can build discrete H-bridge (which is general way to control DC motor rotation direction) or use some integrated bridge like L298, LMD18201 or similar. For buttons see any microcontroller related tutorial, this is the most basic thing ever. As for lcd, if is has HD44780 compatible controller (which i'm almost sure it has) you

Please help to interface JHD12864 graphic lcd with 8051. please post circuit diagram for it. and also help me that how to use it because i don't know how to program it. please...!!!
I found few things 1. Contrast pin needs to be connected through 10K preset 2. In 4 bit mode you need to connect pin D4 through D7 of lcd to micro, But i cant see D4, D5 connected to micro. Instead D0 and D1 connected to micro Google you can find a lot of circuits and example codes
im going to post this here too..... :? :oops: Ok, here's the thing: Im making this project...which envolves 3 AT89C52... 1 is the Master the other 2 are slaves.... all the embedded stuff is done including 4 DS1620 as temperature sensonrs, 1 keypad and 1 lcd.... My problem started with the interface with the (...)
You can obtain lcd standard in 2 ways, Parallel or Serial interface. The most common for 2 x 16 is Parallel so you will need say 8 bits data, RD, WR, CS lines at least for the interface to it. As a bit bash exercise it is not too bad in C. For the temp sensor i would suggest it is a di
I am using AT89C51 to run a 24 seg, 4 com lcd using HT1621 driver. I am using C with Keil uVision. Using the code below, all i get is 8 on segments. no matter what i write, those 8 segments will go on. rest of the segments will stay off... The segments which are on correspong to addresses 3, 4, 5 and 6 of HT1621. Please also explain why are
For calibration and zero you can use digital potentiometers (See Maxim-Ic web site for data sheets on selected units, example here: ). Here are some examples of connecting lcd display and keypad to 8051-family:
