The Theory of PIC Programming

Frustration! Have  you ever experienced frustration when you didn’t have a PIC programmer handy?  Your programmer breaks or you loaned it out to your buddy and you sit just twiddling your thumbs.  It left you feeling powerless because you couldn’t test that great idea, didn’t it?   If so, you share experiences similar to mine.  It is annoying at the very least and does not help creativity.  Or maybe it does ...

Button Debouncing using PIC16F84 Microcontroller

I apologise for the tardiness of this article; for the next little while, I will probably have to scale them back to once every two weeks or so. The reason is that I am proof reading the "Galley Proofs" of my new book, "PC PhD". This book discusses the PC's hardware and how to develop interfaces (along with the required software) for it. I'll be putting more information about it on my web page as the August ...

PICMicro Project using PIC16F84 Microcontroller

In the past two weeks, I discussed the prerequisits for starting your first application and the issues surrounding PICMicro programmers and what to look for. With this background, I am now ready to present what I think is a good first application for somebody learning about the PICMicro. This circuit is not as simple as what I started with in "Programming and Customizing the PIC Microcontroller", but can be ...
