How-to: Bus Pirate v1, improved universal serial interface using PIC24FJ64GA002

We use the Bus Pirate to interface a new chip without writing code or designing a PCB. Based on your feedback, and our experience using the original Bus Pirate to demonstrate various parts, we updated the design with new features and cheaper components. There’s also a firmware update for both Bus Pirate hardware versions, with […]

Interfacing of PIC12F675 with (i2c based) 24LC64 EEPROM (code + Proteus simulation)

This post provides the code for interfacing 24LC64 EEPROM with PIC12F675 microcontroller. This 24LC64 EEPROM has i2c based interface and PIC12F675 doesn’t have any built in i2c modules, so software i2c module is created in the code. This code is written in C language using MPLAB with HI-TECH C compiler. You can download this code from the ‘Downloads‘ section at

PIC USB HID (Human Interface Device) Interfacing

For long time, UART is the only and best way to interface with PC. It is easy to adapt and handle. Though some devices (like: GSM modem etc.) have UART on themselves, but for interfacing with PC, there is only one thing now and that is USB Introduction The purpose of this article is to

How to use PIC18F4550 as a SPI Slave Transmitter

The Serial Peripheral Interface (SPI) is a high speed, synchronous, serial communication standard. This communication protocol is basically a Master Slave implementation where the master device controls the clock based on which the slave devices operates. The master can communicates with one or more slave in the system through SPI bus. The SPI bus requires a

Turntable Photography Equipment using PIC16F84A

A friend asked me if I could build him a device that would allow him to take photos of his products in 360 degrees. That kind of photo is actually an animation that consists of several photos of the same product but from different angles. It means that we need a device that can be

AT Keyboard Interface V1.04 using PIC16F84

Introduction Sometimes you only need a simple and cheap RS232 terminal to get sufficient control over a PC or a RS232 device. There is no need, no space or even no power to place a monitor, a computer case and a keyboard. Maybe there exists also the problem, that the PC or the device is

HandySwipe portable magnetic card reader using PIC16F688

The HandySwipe provides a portable magnetic card reader interface and display. It collects card data from a “Type 2″ card reader (shown here), and displays the data on a small character LCD screen. Type 2 stripes are by far the most common in use, such as on credit cards and drivers’ licenses. The device can

LCD interface with Microcontroller PIC: Beginner’s guide using pic microcontoller

How to interface LCD (Liquid Crystal Display) display module to PIC microcontroller? LCD is a passive component, that is it does not make any light but just modifies the light passing through it for alphanumeric displays. LCD is exclusively manufactured to be used with microcontrollers, which means that it cannot be triggered by usual IC
