PIC Journey: Navigating the World of Microchip's Microcontrollers

Welcome to "PIC Journey: Navigating the World of Microchip's Microcontrollers".

In this comprehensive learning series, we invite enthusiasts, students, and professionals alike to embark on an exciting voyage into the intricate world of PIC microcontrollers by Microchip Technology. Whether you're a beginner curious about the fundamentals or a seasoned tinkerer looking to expand your skillset, this journey is tailored for you.

The projects shared in this repository are educational in nature and aim to introduce beginners and hobbyists to C and Assembly programming for PIC10F, PIC12F, and PIC16F microcontrollers. I myself, at the time of writing these lines, fall into the category of a beginner in projects involving Microchip microcontrollers. However, I decided to document this journey. I believe this initiative may help other interested parties who wish to embark on a similar journey.

With that said, if you find any errors or opportunities for improvement in the projects shared in this repository, please let me know.

The projects folder contains several projects involving circuits with the PIC16F628A, PIC16F887, PIC12F675, LEDs and sesors that may help beginners. Throughout my learning journey, I made a point of documenting every step of the development of each project, including the source codes. I believe that this detailed documentation can offer the target audience valuable shortcuts for developing more complex projects. The "Content" section below references each project, with links to the full documentation and source codes.

About Me

I hold a Master's degree in Educational Technology from the Federal University of Ceará, where I delved into the ways technology can enhance learning experiences. My passion for computer science led me to specialize in it, focusing on Distributed Systems Development with an Object-Oriented approach, at the University of Brasília. My academic journey began with a Bachelor's degree in Information Systems from the União Pioneira de Integração Social (UPIS-Brasília). Outside the classroom, my main hobbies are electronics and Amateur Radio.

PIC Microcontroller Programming Tools

K150

The K150 is a low-cost, high-performance PIC programmer. It is designed to support a wide range of popular PIC microcontroller chips. The K150 allows for various operations such as reading, writing, and encryption of the microcontroller's memory. One of its key features is the use of high-speed USB communication, which facilitates faster programming compared to some other programmers like PICSTART. The device's programming speed and quality are reliable, making it a suitable choice for both hobbyists and professionals working with PIC microcontrollers.

To use the K150 PIC programmer, several key components and steps are required:

  1. K150 Programmer Hardware: The primary device needed is the K150 programmer itself. It's a compact unit designed specifically for programming PIC microcontrollers.

  2. Computer with USB Port: A computer (Windows-based, typically) with a USB port is required to connect the K150 programmer. The computer acts as the host for the programming software.

  3. Programming Software: Software compatible with the K150 is needed to interface with the programmer. This software is used to write, read, and transfer the microcontroller code. Popular choices include "PICPgm Programmer" or "Microbrn".

  4. Device Drivers: Appropriate drivers must be installed on the computer to ensure that the K150 programmer is recognized and can communicate effectively. These drivers are usually available on the website of the K150 manufacturer or from the software provider.

  5. USB Cable: A USB cable is used to connect the K150 programmer to the computer. This cable is essential for data transfer and powering the device.

  6. PIC Microcontroller: The specific PIC microcontroller that you intend to program. The K150 supports a wide range of PIC microcontrollers.

  7. Source Code for the PIC: The actual program or code that you want to write into the PIC microcontroller. This code is written in a suitable programming language, usually Assembly or C.

  8. Basic Knowledge of PIC Programming: A fundamental understanding of microcontroller programming and operation is necessary to effectively use the K150.

Once everything is set up, the programming process involves connecting the PIC microcontroller to the K150, using the software to load and transfer the code, and then writing the code to the microcontroller's memory. The K150 provides a cost-effective and user-friendly solution for programming PIC microcontrollers, making it a popular choice among hobbyists and educators.
