How-To: Web Server On A Business Card (Part 1)

September 18, 2008 by 34 Comments

For years, Microchip PIC microcontrollers dominated; PIC16F84 hacks and projects are everywhere. The 8-bit 16F and 18F lines are supported by several coding environments and easy-to-build serial port programmers. Microchip’s 16-bit PIC24F is cheaper, faster, and easier to work with, but largely absent from hacks and projects.

We recently used a Microchip PIC24F microcontroller in a mini web server project, but didn’t find many introductory references to link to. In this article we’ll cover some PIC 24F basics: support circuitry and programming options. We’ll also talk about our favorite features, and how we figured them out. Our next article will outline a web server on a business card based on the PIC 24F.

PIC Controller Cable Tracer

June 18, 2008 by 3 Comments


[Kevin Gorga] submitted this PIC controller based wire tracer to a project contest last year over at circuit cellar.A 125Khz signal is injected to the target cable and a pickup coil is used to detect the field and identify the wires location. You can grab the full project schematics and code here. The rest of the entries are pretty sweet, so be sure to check them out.
