PIC Tutorial

Programming a microcontroller in assembly languages takes time and to reduce that time, embedded systems engineers often have tricks up their sleeves. One of those tricks is the use of lookup tables. In this post, I will share how I use lookup tables in assembly language for the PIC16F84A microcontroller.

Lack of pins to use is a common challenge in designing microcontroller-based projects. This is particularly true when dealing with liquid crystal or seven-segment displays. Multiplexers and display drivers are great help but at an additional cost. Thankfully, a software-based solution exists to solve such a problem.

The PIC16F877A microcontroller comes with a Capture Compare PWM (CCP) module which utilizes its 16-bit Timer1 module to generate or count pulses, among other things. I have already covered how to generate PWM in my previous tutorial. This time, we will look at how to implement capture and compare with …

Last time, I showed how to get started with Microchip’s Curiosity HPC board. I will now explore the use of the included buttons and LEDs on this microcontroller board.

We have managed to blink an LED and use interrupts and timers with the PIC16F84A. Sadly, that’s almost all we can do with that microcontroller as it lacks features that most microcontrollers or Arduino have. From here on, we will now be using the PIC16F877A.

A water level sensor is a simple device used to measure the level and volume of water inside a container. This tutorial shows you how to use a water level sensor with microcontrollers like an Arduino or PIC.

You can in fact build your own motion sensor without spending too much. Motion sensors can be set up using ultrasonic transceivers, video cameras, or microwave signals. In this tutorial, I’ll show you how to use the PIR motion sensor with a microcontroller. PIR is short for passive infrared which …

You can drive an LED on or off using a microcontroller like Arduino or PIC. There’s no problem there because the 20 mA or so current from the pins is enough. You can’t drive loads that require much more current like a motor. This is where the L298N motor controller …

Pulse width modulation may have been invented to encode messages into pulsing signal but it was originally conceived as a technique for controlling power supplied to motors. In this tutorial, we will look at how PIC16 PWM works.

In this post, I’ll share with you how I got the Nokia 3310 LCD to run using a PIC16F877A microcontroller. How to use the Nokia 3310 LCD with the Arduino has been covered before. This one is more challenging because I had to create a library for the XC8 compiler. …
