hi there, I need your help. I need simple code for pic16f84 & lcd 2 X 16. I have also 4MHz crystal connected to the same chip. I want to use all 8-bits to connect them to that pic16f84. The problem that I can't add any extra parts accept some capcitors and resistors. I'm looking forward to see your feedback. I have MPLAB wh
I have a simple pic16f84 lcd design which actually works with test board. I'm trying to get familiar with Proteus ISIS so I implemented the desing to it. The simulation seems to work (those blue and red dots are blinking) But I can't get anything to the lcd? Hi "mzypt"; You have a problem about the 4bit lcd timings (see the

Hi, For those who want to interface to lcdn C language using CCS Ok. All the lcd functions are ready built in the driver lcd.C file (you will find it in the drivers folder) All you have to do is edit the lcd.C file WHY? Becuse it use the PORTD as a connections to lcd But I use (...)
this code is written in mikroBasic and i used one of their examples for my code: program lcd_demo dim txt as char main: PORTA = 255 TRISA = 255 PORTB = 0 TRISB = 0 lcd_Init(PORTB) lcd_Cmd(PORTB, lcd_CLEAR) lcd_Cmd(PORTB, lcd_CURSOR_OFF) txt = "testing" while (...)

Can anyone tell me is it possible using pic16f84 for serial port transmission, lcd display and keypad? I scare that pic16f84 dont have enough port.
hi I come across: does anyone have schematic or circuit diagram for this project? Thanks
I built switching inteligent battery charger with MAX712 with discharging unit, and now I want to add digital V meter (15Vdc max), A meter (3A max) and I want to measure battery capacity while is connected to discharging circuit. Charge-discharge is automatic with LED signalisation so I can get control signal from 3 LEDs (charge, discharge, finis
Does anybady have schematic and hex file for dual channel Volt meter, and dual channel Amper meter in one PIC 16F84? Vmax=35V dc Imax=3.5A
I do not use Morse Code reader - I read CW myself. I think that reading by microcontroller is not so reliable. But if you need circuit you can find it in QST August 1999 "A pic16f84-Based CW Decoder" . Updated software for programming the pic16f84 and the PC-board layout diagram in Circad. :

Hello everybody, I have bought a lcd display but I don't know how to connect it to the PIC. The display is EI62585 ,C20408tr-08 ,050316 (i don't know which number is the moduls' number). Does anybody has the datasheet of this display or a circuit with pic16f84? Thank.
Hi, I'm a student and I'm graduating this school year. And for our final project, we need to create two wireless messengers that could communicate to each other. Could there be anyone who could help us with this? I would just like to ask if you might know of a site or of a schematic/code that could help us in interfacing our 20x4 lcd with a 4x4

Hi, I want to connect my lcd to PORT A of my pic16f84 mc but i think the connection is only possible through port B...But my port B is reserved for interrupts..
I wanna make a design that makes shifting text.I.e. I make a 7x5 led system.and the letter "I love you" shift on it from right to left. I will use pic16f84 or 84-A. But I have no idea about shifting. I think I should use HC154 or like it. Do you advise any documentation that I could easily understand this project and easily set it up [c
I saw some examples to drive a diferents NOKIA lcd (3510i) whit pic's on internet but I'm new in this matters. Someone can help me to drive this can of lcd (Nokia 3586 or 3520) . I guest than both are similar as Nokia 3510i. (I need the schematics and pic code ) I'm based on this information:

Hello everybody! I'm new here and I hope we'll go on well :) I've come here because I'm working on a project with a PIC 16F84 which I'd like to use to control a 2x16 chars lcd display (Hitachi HD44780 driver). I'm programming in C as I have already programmed in this language and I know most of it. But this is my first time

well, unfortunately u can't use pic16f84 cause it doesn't have onboard ADC (analog to digital converter) and this is necessary to be able to read the signal in the microcontroller .... hope that is useful info thanks, Salma:)
Hi all, I need a VHF 2m PLL that uses a MC145170 PLL controlled by a PIC16F628 or PIC12F629 or pic16f84 and so on and a lcd display (to show actual frequency) with RX/TX automatic shift frequency (IF 10.7MHz) to be used in an old commercial VHF radio to replace a MC145146PLL module. 73, Fernando - Call sign PU2PLL
hi, We are doing a project on wireless messenger. I would like to ask if it is really needed to use an encoder/decoder on your rf module when interfacing it to pic16f84? I'm also using a 4x4 keypad and an lcd interface with this. I would appreciate your help.
Hello all. I am looking to build a diagnostic circuit for amplifier, with lcd display and pic16f84 OR PIC16F877, to check Power supply, DC Fault, Overload. Speaker Impedance , Fan Control. Any comments about this circuit, suggested circuit diagram, suggested software? PLease help. Sam.
I use pic16f84 to measure the time width of TV remote of 9th pulse, it is 1.7ms. The circuit is OK and the time width is displayed. IR receiver output is connected to pin b0. But after the code is measured, pin b0 of 16f84(external interrupt) is always low, so it cannot trigger more than two times. I am sure the 16f84 is good , the code is as foll
I am writing a small program to drive lcd where I change the I/O line for Hi/Low digital signal however when I write for a second time to either Port A or Port B the voltage on the output rise and fall instead of being fixed 5V or 0V. This onlt happens after the second MOVWF is issued, if i reprogram with out the second MOVWF then all voltages are

direct connection will work fine, have a look at this example: RF Modem Robotics Project :wink: IanP I read your link and it uses pic basic pro serout command (serout 1,n9600,(B0)) with pic16f84 pic. But pic16f84 does not have a UART. I am using PI
Hello, Is there any good guide in getting started in embedded C and Hitech PICC? I have red some tutorials on the pic16f84 and assembly programming on it but I need to get started on embedded C. I am a web programmer so I am able to understand what I am reading, I just need to know the embedded C rules/definitions etc. sources with examples
I'm still working with lcds and pic16f84. I've written part of a 4-bit independent pins driver, it's working fine most of it. What I want to do now is to create a function that reads the busy flag and the address, but I'm not sure how to proceed. The HD44780 manual says I can read it with a busy flag request, like this: [code
An energy efficient design would refer to an inductive boost converter. There are plenty of ready-to-use ICs for this purpose. You didn't specify a load current. Load current exactly not known. It will be used to power a pic16f84, 628 or similar micro and an lcd (no back light) 5V would be enough, but some components ne
The 5110 and 3310 displays are quite similar, same controller, resolution, and almost the same pinout. The following blog includes assembly source for the pic16f84, which can be easily ported to virtually any PIC16F series, including the PIC16F877A. Nokia 3310 lcd how-to [synt
