Welcome to Clifton Laboratories, the page of Jack Smith, K8ZOA, author of Programming the PIC Microcontroller with MBasic. I'm currently working on several PIC Microcontroller amateur radio-related projects.

Introduction

Click on any of the images below to learn more about it, or follow the navigation links to the left.

See the updates page for the current project status. I’ve also added a page with images of sample modulation types.

I’ve uploaded the crystal motional parameters notes (PDF format) to the web site. This is not a polished, ready-for-publishing article, but is more of a summary of my workshop notes, with photos and plots.

I’ve also uploaded several Z90 documents (all in PDF format):

Quick Operating Instructions (the name is misleading; this is the Z90 draft User’s Manual)

Z90 & Z91 Schematic

Assembly Instructions

All of these documents are based upon the prototype boards and are “works in progress” to be reviewed for consistency and updated to reflect changes before the first real kits

My book, Programming the PIC Microcontroller with MBasic, published by Newnes, 2005.

Newnes has combined chapters from eight PIC Microcontroller books into a single compendium, PIC Microcontrollers: know it all. Six chapters are from Programming the PIC Microcontroller with MBasic.

Visit Larry, N8LP's page to see his PIC Microntroller ham radio projects I've known Larry since we were both college age ham operators in suburban Detroit in the 1960's. You'll like his projects. Here’s his latest project, the LP100 wattmeter, a state-of-the-art HF wattmeter kit, with real-time R+jX impedance display as well as power and SWR.

The 18F4620 PIC Microcontroller in the Z90 and Z91 SpectraScreen is programmed with Mecanique's Swordfish compiler.

Mechanique has made available a free version of its Swordfish compiler, Swordfish SE, available for download at its site. Click on the icon to the left to go to the main Swordfish site.
