This project uses Myke’s 2-Wire LCD Interface from last week and will help teach you “Graphics Animation” using LCD’s. Last week, I showed how the PICMicro could be connected up to a Hitachi 44780 LCD using only two wires. This week, I wanted to use this circuit and show how simple graphic animation can be […]

This post provides the LCD[1] interfacing code in 4bit mode using PIC16F84A microcontroller. This code is written in C language using MPLAB with HI-TECH C compiler. You can download this code from the ‘Downloads‘ section at the bottom of this page. It is assumed that you know how to make an LED blink with PIC16F84A microcontroller. If you don’t then please read this

This post explains the idea of creating custom characters on any LCD ( e-g on 16×2 LCD ) which has HD44780U controller in it. Almost all 16×2 or 20×2 LCDs have HD44780U controller in them[1]. This controller provides the functionality of CGRAM ( Character Generator RAM ). We can write character patterns on this RAM

Here in this post i am going to teach you how to display images on Graphical lcd using Pic Microcontroller(16F877). I am using JHD12864E graphical LcD in my Project. JHD12864E is 128×64 dimension lcd. 128×64 means it has 128 coulombs and 64 rows. So total dots it has is 128×64=8192. You can display an image of maximum size(Dimension =

Recently I got my hands on a couple of HSDL-1100 based IR transceivers and a KS070B LCD display module. This was a nice opportunity to experiment with three things: (1) controlling an LCD module, (2) serial communication between two PIC microcontrollers, and (3) making this work over an IR link. Serial protocol supports addressing of

Displaying content on a normal alphanumeric display is very limited ,we have to be limited with the font size and we can’t draw any graphics also. but convention Graphics lcd are really very expensive so here is the solution, you can use Nokia 3315 / 3310 monochrome LCD to display your large font text and graphics . the reason behind using

Introduction An HD44780 Character LCD is a liquid crystal display (LCD) display device designed for interfacing with embedded systems. These screens come in a variety of configurations including 8×1, which is one row of eight characters, 16×2, and 20×4. The most commonly manufactured configuration is 40×4 characters, which requires two individually addressable HD44780 controllers with

Many times when I’m working with a small MCU such as 8 pins or 18 pins MCU. I found that I don’t have enough MCU pins for parallel LCD display. So it’s good to have a one-pin-require LCD module for experiment. Acctually, serial LCDs are sale on the market but still I built it myself

The project demonstrates the implementation of the sound spectrum analyzer for 8-bit microcontroller PIC18F4550 manufactured by Microchip . Spectrum analysis is performed using an optimized fast Fourier transform algorithm (Fast Fourier Transformation, FFT), written entirely in C language. Data Visualization (spectrum) is carried out in real time on a graphical LCD display with a resolution

4 prototype boards arrived today. After going over them carefully, I found 4 lines that crossed each other. After some quick surgery with a knife and some solder and wire, the IDE project is now semi portable. The power supply is still out of a PC, so it’s tied to an AC outlet. I’d like
