How to display text on 16×2 LCD using PIC18F4550 Microcontroller

Several automated and semi-automated devices require a message to be displayed in order to indicate their working status. In continuation to LCD interfacing with PIC18F4550, this article explains how to display a message or string on a 16x2 character LCD. Programming steps: ·         Configure the LCD. ·         Store a string in a character array. unsigned char data[20]=“EngineersGarage”; ·         Run a l ...

PIC16F877A (with LCD) not working

I have designed a PIC18F877A micro controller project to read temperature from an LM35 using ADC, display it on an LCD and transmit it to a serial port. When the program starts, sometimes it shows a startup message - sometimes it doesn't display anything. Also, the serial port connection is not working. Can anyone help - am I missing something? Are there any ground connections missing? My code: #include #de ...

d.i.y. Handheld Multichannel Analyzer (MCA) based on 16F877 PIC Microcontroller and LCD

Some time ago I was developing a medical instrument which required histogramming, which got me in the mood to retake my own PIC MCA project(http://home.comcast.net/~prutchi/index_files/scint.htm ). I used the variable RAM in the microcontroller (16F877), so I limited the number of channels to 95 and let the histogram run until some channel reaches 240 counts (the highest 8-bit number that yields an integer ...

Easy Debugging Terminal using PIC16F84

Introduction This LCD terminal provide two modes of operation by selecting jumper J1. When J1 is open the terminal operate as a normal ascii display terminal, when J1 is closed the terminal displays the input serial data in hexadecimal format. This mode is useful for viewing raw data from the serial port output. Hardware Figure 1 shows the circuit diagram of the Easy Debugging Terminal. IC U2 a PIC16F84 mic ...

How to create custom characters on 16×2 LCD using PIC18F4550

The 16x2 character LCD can also be used to display custom characters other than numerals, alphabets & special characters. Refer LCD interfacing with PIC. Some special shapes like hearts, arrows, smileys etc. can easily be displayed on the 5x8 pixel pattern of character LCD. These shapes are first stored at a special location in LCD’s controller and then displayed on the LCD module. This procedure has be ...

4 Bit LCD interfacing and programming with PIC Microcontroller

LCD displays operate in two modes 4 bit and 8 bit mode. We all might have been familiar with 8 bit mode which is used widely in several systems. But 4 bit mode is something which many of us is not aware of. This mode has some advantages over the 8 bit mode out of which reduction of dedicated data pins is most important. This tutorial will teach you 4 bit LCD interfacing in 4 bit with your controller as well ...
