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 (...)
how to interface lcd with 8051?............... ---------- Post added at 12:46 ---------- Previous post was at 12:46 ---------- #include sbit rs=P3^5; sbit rw=P3^6; sbit en=P3^7; delay(unsigned int i) { while(i--); } lcd_cmd(unsigned char c) { P1=c; rs=0; rw=0; en=1; delay(150);
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.
please if any one know how i can make interface of 3310nokia lcd with(microcontoller LPC2138 or by pic 16f877) please send your code by( C languge) and send conection to it tanks for any help
hi guys. this is the project i want to do. using an 8051 i want to build a system where when u want to enter, u press a "start" button. then, the the system displays on the lcd asking you to enter your password/code, and after you code is verified, the next step is to use a "barcode" that was given to u. the system scans it and access is gr
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.

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 (...)
