The photo shows a PIC16F84 microprocessor board tethered, by ribbon cable, to a circuit having 8 LEDs and an 8-position DIP switch. Learning a microprocessor’s capabilities often demands such a setup where LEDs turn on/off, blink at desired rates and respond to switches. This tutorial serves to quickly accelerate your PIC16F84 development ambitions. Motivation and […]
Description The ENC28J60 is Microchip’s first incursion into the ethernet controller arena, this new device includes all MAC & PHY IEEE 802.3 10BaseT functions, 8KB of dual access RAM packet buffer and a SPI serial interface, all in a convenient 28-pin package (SPDIP, SOIC, SSOP and QFN packages available). It takes just few components to

Introduction I get a number of emails every month asking about creating USB devices using the PIC18F microcontroller. After looking at projects such as my Atari Joystick USB Adaptor and C64 VICE Front-End there seems to be a demand for more information on how to ‘hack your own’. In this article I will show how
The 24FC1025 is a serial I2C EEPROM memory fabricated by microchip, it has 1024Kbits (128KB) of memory space and it is divided in two parts each one of 512Kbits (64KB); the first part goes from address 0x0000 to 0xFFFF and the second part goes from 0x10000 to 0x1FFFF. Features: 128KB of memory space 2-Wire serial
Introduction There are varieties of digital temperature logger projects available online based on different microcontrollers. The one I am going to talk about is based on a Microchip’s 8-pin microcontroller, PIC12F683. It reads temperature values from a DS1820 digital sensor and stores in its internal EEPROM. PIC12F683 has 256 bytes of internal EEPROM and we

Old Alarm Clock Problems wake’s Quozl’s wife, a side-effect, needs to be armed each evening, 12-hour clock, cannot be armed more than 11.5 hours before alarm time, triggers at plus or minus ten minutes, depending on how it was dropped, battery cover needs to be removed to change time, changing time at daylight saving loses
INTRODUCTION The idea for creating a USB sound card based on a PIC came from discussions of other people creating one on the Microchip USB forum. The hardware of the card is based on all Microchip products. The software uses a modified version of the Microchip USB framework which is interrupt driven instead of the

Digole 12864ZW is a 128×64 pixels graphic LCD that can be found at attractive prices and this is why it started appearing in projects across the web. It is based on ST7920 chip which is not so well known and to me it wasn’t the easiest to work with.’ The documentation for this display can
Cheap PIC Programmer This programmer works only with PIC16F84 but it’s great because it never causes errors and works with almost all computers,unlike some other homemade programmers. Step 1: Step one : Materials For this programmer you won’t need many materials.In fact , you will find all you need in your local electronics shop 😉

This project started life a long time ago, with the intention to build an iPod clone, back when personal MP3 players were an expensive luxury and long before you could buy them from China on ebay for less than a light bulb. The plan for the MP3 player was to use a PIC microcontroller connected
