How to drive a Dot Matrix LED Display. using pic microcontroller

Driving a 64 LED dot matrix LED display is quite simple and just requiresONE TRICK! Here you can find out how to drive an led dot matrix with 64 LEDs (8 rows by 8 columns - 8x8 display) or less e.g. 35 LEDs (7 rows by 5 columns - 5x7 dot matrix). However the principle remains the same for larger displays - you may need more processing power and driver circuitry though. It uses persistence of vision to let y ...

Making your own Digital Clock using PIC16F887

Small LED dot matrix development board I was very busy for the past two months so this blog just didn't move. As you may know, the LED dot matrix display is my favorite device. I have designed a small development board for testing my led dot matrix related programs. The PCB is single sided so I can make it at home. Most of the components are SMD to keep small footprint of the board. The PCB size: 58.4mm x 4 ...

How to drive an led display matrix using PIC16F88

Here you can find out how to drive an led matrix with 64 LEDs (8 rows by 8 columns - 8x8 display) or less e.g. 35 LEDs (7 rows by 5 columns - 5x7 dot matrix). It uses persistence of vision to let you drive the 64 led matrix with only 10 microcontroller outputs! Normally you would need 64 outputs for 64 LEDs but by using multiplexing and a helper chip you can get away with 10. LED Display multiplexing simply ...

PIC12F675 interrupt based software UART code and Proteus simulation

This post provides the interrupt based software UART (Bit Banging) code for PIC12F675 microcontroller. As we know, PIC12F675 microcontroller doesn't have built in UART module, so we can create UART functionality in it's software. This post provides the details of how to program software UART functionality in PIC12F675. This code is written in C language using MPLAB with HI-TECH C compiler. You can download ...

Build A Digital Tachometer/RPM Counter using PIC18F452

A tachometer is a tool that mechanics or engineers in general use very often. A normal tachometer will be able to tell you how fast something is moving in a complete rotation. A good example is on cars, you will see a tachometer counting the RPMs of your engine. With the new smaller microcontrollers and some simple circuitry, it's actually very easy to build your own digital tachometer. This tutorial will m ...

Make your own USB LCD controller using PIC18F2550

Hi everybody Ages and ages ago, I posted this and many people said they'd like a guide. So here it is! This is a guide for making an LCD that connects to your computer using USB, primarily intended to be external. You can see mine here. To make the board smaller, it doesn't have the GPOs. This thread should also be used for suggestions on how to improve the circuit, add new features, and fix bugs in the fir ...
