I think, your RS pin from lcd1 is connected to a floating pin on pic (RE0) and your code is putting RB0 to ground. are you supposed to connect RS to RB0 ? I don't know basic pro, I use C. Make sure you're initialising lcd properly in your code (with specified minimum delays). I've simulated same lcd with 8051 and (...)
No, the lcd needs to be initialized by the micro, through some commands. Are you running anything on the pic? Perhaps the code is not right, or the timing, or... there are a few things that can go wrong.

Can anyone help me find a replacement???? This is an 2x16 lcd COG. It uses a 24 pin header. It goes into a Meade Autostar hand controller. And yup, Meade wont sell me just a display. The closest I have found was an Optrix DMC-50747NF that no one stocks or is willing to sell in single quantities. Please HHHHeeeeeellllppppppppp [em
hi; i have a project about write persian or arabic word on 2x16 lcd. How to make ?
the example of picC work fine so i think your problems is hardware.Check if any pin of lcd is connect with other or with power.
Hay I want interface 2x16 lcd with LPC2106 in 4 bit mode I have tried the following code but I am not getting proper out put Please Check the code. #include"LPC210x.H" #define RS_1 IOSET | 0x00000800 // RS=P0.11 #define RS_0 IOCLR | 0x00000800 #define EN_1 IOSET | 0x00000400 //EN=P0.10 #define EN_0 IOCLR | 0x00000400 /

Hi, for the past few days I've been playing around with a Spartan 3-AN Starter Kit Board. I'm interested in learning as much as I can, but now I'm stuck, and need a fresh pair of eyes to look over my code, and correct me where I made a mistake... I'm trying to initialize and write something to the 2x16 lcd display that comes on the board (S6A00
hi! in our project we had 20*4 lcd display,we used lcd just to display few characters.our code was also written in microC,i am giving you some part of it below,see if it is helpful to you-- we had written separate display function-- void display(unsigned short cursor,const char *dis) { lcd_Cmd(cursor); while(*dis) { (...)

Hi I am new in DSpic33 . before I use character lcd for my project with AVR. Now I want to interface 2x16 lcd with DSpic33FJ64GS610. As you know in this DSC the place of one port is not at one place . (for example RA0-->Pin17 , RA1-->pin38) So for easy making PCB for my circuit I want to connect (...)
how to send a variable to display in 2x16 lcd for example ; unsigned in a = 9; lcd_data(a); how does display as 9.( means that the value of a; ie = 9) thanks
Hi guys, I have a strange problem with displaying text/characters on my blue backlit 2x16 lcd screen. The code is working correctly and if I look the screen with an angle, I can read it. However it cannot be read by looking the screen from above. Here I am attaching the photos of my problem: 102483102484
Good day, I writing a driver for my 2x16 Hitachi lcd using a pic Microcontroller. There are some problems that I observed from my lcd setup. First, I need to turn the variable resistor from maximum to minimum connected from ground to pin 3 of lcd module everytime I power up my lcd. (...)

You have to use A/D converter of pic and implement a conversion table on code based on sensor chart. for displaying on the lcd screen, i think you have an in-built controller on lcd. For code you can search in piclist forum at
you can download circuit cellar from may 03 from, issue 154 here is with pic 16F84A
I'm using Hi-tech picC-lite compiler,it comes with some sample C codes.The routines in lcd.c work quite fine for 16F84 but when I change to 16F877 with the same pin connections nothing promts on lcd. The code is below.... Thanx in advance... /* (...)

hi, i m building lcd and pic based project and encountered few problems : 1. pic16f877a has 2 pins for vdd and 2 for vss. i checked them with voltmeter and they are shorted do i have to short them with wire ?? 2. when working with 4 data line mode of the lcd do i have to connect the other unused lines of the (...)
Try this: You should also read datasheet for your lcd. I hope this will help you. If you have further questions go ahead.
I realize problems connecting a (3,3V) msp430f135 with a standard 5V 2x16 lcd. As far as i know, msp430x1xx doesn't have 5V tolerant pins. That means at least it is not recommended to accept as an input logic levels of 5V, right? But in MANY commercial development boards with msp's i have see direct connection of PORTx to a 5V lcd. My (...)
plz, can anyone pls post a simple lcd code for me? I just need to know how to show a word in a 2x16 lcd. I'm using Microchip pic16F877A at the same time i want get signal via RF modul Preferably pic C language! I try the routine provided by them but still doesnt work. Thanks for help
hi friends i want a help from u..... i want a "C" code for get the signal from RF module & display the lcd display board via pic 16F877A here i used portD for lcd & pin RA2 for RF module. plz help. thanks for ur help
Hi everyone! I have an lcd 2x16. It has 16 pins. I read the data sheet and i connected it to power supply +5Vdc. The first pin is connected to Gnd and the second pin is connected to +5Vdc.

<<>><<>><<>><<>><<>>Hi all!<<>><<>><<>><<>><<>> I am recently working on some LED multiplex display with pic. This parallel type type interfacing is bit more critical and a lot of shift register or decoder have to use. But a lcd display is easy to interface to any pic. They are cheap & if we use them many port of (...)
Here is the code I use for a 2 line 20 char lcd display using the pic 16-bit micros. This uses an 8-bit interface. Attached is a pdf with the lcd commands. Should be possible to convert it to assembler. /*--- Macros ---*/ #define RS LATDbits.LATD8 #define RS_TRIS TRISDbits.TRISD8 #define RW LATDbits.LATD9 #define RW_T
This is should be very easy to do and create But what do you know about pics and lcd what language do you want to use picbasic ASM or c
You can buy a pickit2 or compatible pretty cheap. I'm clearing out the old Inchworm PCBs (RS232 ICD2 MPLAB)
I want to connect LM35 temp sensor with pic 18f452 and display reading on lcd,when i simulate it on proteus i get strange symbols (like #,! etc) instead of reading of temp sensor . plz help ,my C coding in mplab is #include #define rs PORTBbits.RB0 #define rw PORTBbits.RB1 #define en PORTBbits.RB2 void lcdcmd( char ); (...)
Am using CCS C ,MPLab and Proteus. Please explain me the steps to display the message "hello" on 2x16 lcd using pic16f877. I know the hardware configs...
