Eight-Pin Projects
Column: Getting Started With PICS
November 2009
I recently received a development setup that I found quite interesting, as it’s targeted at my favorite audience—the beginner market. It is called the CHIPAXE system.

Programming the PICDEM 2 Plus Development Board
Column: Getting Started With PICS
September 2009
After getting everything set up — I used an MPLAB® ICD 2 for the programming tool because it is available bundled with the PICDEM 2 Plus board — I was ready to write some code.

Improving the PICKit 2 Development Board
Column: Getting Started With PICS

PICKIT™ 2 Command-Line Option
Column: Getting Started With PICS
January 2008
I have good news for all the users of Microchip Technology’s PICkit 2 programmer who want to use it with an Integrated Development Environment (IDE) other than Microchip’s MPLAB® IDE. Microchip has released a DOS command-line option for the PICkit 2, and I’ve successfully used it with the MicroCode Studio IDE from Mecanique (http://www.mecanique.co.uk) and microEngineering Labs’ PICBASIC PRO™ sample version (http://www.microengineeringlabs.com)...

Assembly Language Programming
Column: Getting Started With PICS
March 2008
When I started programming microcontrollers (MCUs), assembly language was the only real choice. I didn’t even know what a compiler was. Now, it seems many beginners and even experienced programmers tend to fear — or at least try to avoid — using assembly language. I will admit that the latest variety of C compilers and Basic compilers make programming much easier, but I still feel it is necessary for a programmer to understand enough about assembly language to write a simple program...

Getting Started With The PICBASIC™ Pro Compiler And MPLAB® IDE
Column: Getting Started With PICS
May 2008
Email feedback has made it clear that there are many who would like me to go back and cover how to get started, as the title of the column suggests. Though I’ve covered this in many previous columns, much has changed, and there are still some beginner topics I have not covered.

Monitoring Input Signals
Column: Getting Started With PICS
July 2008
In this month’s column, I want to introduce a common topic involving sensing or measuring input signals. A wise, experienced engineer recently suggested I point out that all MCU projects involve three basic parts...

Convergence 2004
June 2005
When Nuts & Volts asked me to cover Convergence 2004, I said no problem. I usually go there every couple years and I was due to visit again. The show had some very interesting items for the Nuts & Volts reader. First though, let me tell you what Convergence is, in case you aren’t familiar with it.

A Primer For Beginners
Column: Getting Started With PICS
January 2006
A third category of feedback involves readers that have little or no electronics background and with all the different programmers, compilers, microcontroller choices, software options, etc., they are confused and afraid they would waste a bunch of money and still not get what they want. I’m here to tell you it isn’t that difficult and it doesn’t have to cost that much to get started.

Microchip PIC-Based Resistor Checker
Column: Getting Started With PICS
February 2006
This article describes this project and shows how easy it is to use the A/D port with the PICBasic Pro compiler. In fact, I was able to write the code within 31 commands so this could be done with the sample version of PICBasic Pro which you can download from http://www.melabs.com for free.

PIC-to-PC Communication
Column: Getting Started With PICS

This month, I want to address one form of PIC-to-PC communication using serial RS232 format, and you get this one for free (excluding the magazine subscription fee).

Going Beyond 31 Commands
Column: Getting Started With PICS
April 2006
The feedback to my articles tells me this series on programming Microchip PICs is a success. Based on loads of email, I’ve helped many readers get back in the electronics game and comfortable programming microcontrollers. That is a reward in itself and is enough for me because many years ago, I was there, too. That success, though, also invites its detractors...

Using The MicroChip PIC Timers
Column: Getting Started With PICS
May 2006
For this article, I’ll explain timers and then use the Timer 1 peripheral to form an accurate one-second time base. This could be considered an advanced project so don’t be too hard on yourself if it takes a while to completely understand it...

Using The PIC External Interrupt
Column: Getting Started With PICS
June 2006
Life can throw you in many directions and how we deal with it builds our character. This happened to me recently while trying to get this article out for Nuts & Volts...

Developing With A PIC Bootloader
Column: Getting Started With PICS
July 2006
If you’ve been a regular reader of this column and have started to actually program PICs, you are probably tired of moving the PIC from programmer to project and back again every time you make a change. It not only damages pins, but can sometimes cause confusion if the PIC is put in the board backwards or even shifted by one pin. This is why I like to develop with a bootloader and it’s one of the most difficult items to explain to a beginner...

Multiplexed LED Displays And Relays
Column: Getting Started With PICS
August 2006
For this article, I wanted to demonstrate how to control two LED displays from one set of I/O pins in a method called multiplexing. To make this into a project for the reader, I revisited a model rocket launch control box design I did back in high school (long time ago) for an electronics competition...

Real Time Clock
Column: Getting Started With PICS
September 2006
One of the more interesting things I've discovered about the readers of Nuts & Volts is their diversity. Through the emails I've received from writing this column, I've discovered that both hobbyists and professionals read these articles.

USB PIC Programmers
Column: Getting Started With PICS
October 2006
The emails keep pouring in and it’s great. Easy and instant feedback is what makes the Internet so awesome. Though a few people let me know they feel I’m just writing this to sell my stuff, most understand that my goal is to help everyone I can learn how to develop microcontroller-based designs using PICs. I also get several emails from people who have discovered a different Basic compiler and wanted to let me know about its great features. If it gets you programming, then I say go for it....

PIC Hardware Interface
Column: Getting Started With PICS
November 2006
Programming Microchip’s PICs is a lot of fun, especially if you have a nice development board with all the connections pre-wired for you. My BasicBoard, built around the 40 pin Atom chip (16F877A with Atom bootloader installed), was designed just for that purpose. A beginner could get a lot of programming in before they ever have to build custom circuitry around their PIC micro-controller. What I’ve found from reader feedback is a lot of people are looking for a little guidance...

Christmas Music
Column: Getting Started With PICS
December 2006
This month’s installment marks the conclusion of the first year of this column. I want to thank everybody who reads these articles for their support. Since it’s the December issue, I thought I would offer a project related to the holidays. I also wanted to tackle the subject of digital-to-analog conversion. To do that, I plan to have a PIC play a little Christmas music through a small speaker — kind-of like one of those Christmas cards that plays a tune every time you open it up...

PIC12F675 Replaces The 555 Timer
Column: Getting Started With PICS
January 2007
If you have been fooling with electronics as long as I have, you will have seen a lot of changes throughout the years. I watched the birth of integrated circuits which led to op-amps and TTL or CMOS digital chips, and eventually to the microcontroller. Somewhere along the way, an eight-pin chip used by hobbyists all over the world was developed.
