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

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

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

A tutorial on the 12F675 PIC microcontroller which shows you how to program and use it with a series of projects starting out with a simple LED flasher and progressing on to more advanced projects. To use the tutorial files you need to have a PIC programmer with an ICSP output connector and the components shown

This experiment uses the push-button to increment the count on the 7-segment display. The count-value is stored in a file and this value is incremented by the program each time the push button is pressed. The count-value is used to look-up a table to pick up the display-value for the 7-segment display. Additional experiments on the website
