Input/Output with PIC Microcontrollers

PIC16F84A

For most microcontrollers, the input and output channels are handled by data direction special function registers. AVR microcontrollers call them Data Direction Registers (DDR) while ARM-based STM32 has a group of “GPIO” registers. PICs call them TRIS registers which is supposed to be short for “TRIState”. In this article, we …

Using PIC Timer with PIC16F84A

PIC16F877A

In this tutorial, I will discuss how to use the PIC16F84A microcontroller timer module for a variety of applications including turning a LED on and off without the use of a software delay subroutine.

PIC Interrupt with PIC16F84A

PIC16F84A

So far we have discussed how to code microcontrollers sequentially, i.e., the device performs the code from top to bottom and may branch out to labels (via goto) or subroutines (via call). Now we'll be looking at PIC interrupt.

The PIC16F84A - A Beginners Microcontroller

PIC16F84A

We'll start with the PIC16F84A - a.k.a the beginners microcontroller. This MCU from Microchip was introduced in 1998 as a successor to the very first serially programmable PIC, the PIC16C84. The PIC16F84A is often the starting point for learning PIC microcontrollers because it only has 35 assembly language instructions and it only costs less …

An Introduction to PIC Assembly Language Programming

PIC Assembly Language

Most people have nightmares about PIC assembly language programming while some would say it's a waste of time. I've experienced this both so I agree. PICs can be programmed much easier using high-level languages like C and Basic. However, learning to code in assembly helps you learn more about the …
