Steven Pope

Flight Computer for High-Power Rocketry

Steven's ZSAT II flight computer can compile data like altitude and acceleration, and then send it to his cell phone. The eZ8F642-based system includes a Trimble GPS module, a long-range RF module, and a controller for a wireless video camera.

Tom Napier

Real-Time Pulse Generator

Access to faster PIC processors inspired Tom to revisit an old pulse generator design. The result is both a practical construction project and an exercise in real-time programming.

Build a Hardware Accelerator

With a little direction from Amir and Wael, you can implement a hardware accelerator within a soft-core RISC processor in a System-on-a-Chip embedded platform. The accelerator is perfect for a vision system application for a mobile robot.

Romeo Costanzo

Strong-Encryption for PICs

Part 1: Triple-DES Algorithm

Triple-DES is a widely used encryption algorithm. In this series of articles, Romeo shows you how to use it with PIC MCUs. He also describes how he implemented Triple-DES to create a one-time password generator for an electric lock.

Michael Griebling

Hardware Synthesis Using VHDL

Part 1: VHDL Implementation

Michael presents an XC3S200-based timing system that includes a date/time function, an alarm, and a stopwatch. He used VHDL to get the job done.

Simulate First

Simulation Techniques for Testing New MCUs

Simulators are designed to help you debug your code. But as Jeff will show you, you can also use a simulator to get a feel for a new microcontroller and its peripherals. The idea is to play around with an MCU before spending money on it.

Brian Millier

PSoC Pulse Generator

Brian built a digital pulse generator for his home several years ago. However, when the HP pulse generator he uses at work died, he hit the bench and designed a replacement for it, using a Cypress PSoC-based version of his original design.

Reach for Interface Control

Add a GUI to a ZF8042A-Based Design

Fred needed to add a GUI to a ZF8042A-based application, so he turned to Reach Technology's SLCD controller. The controller offloads GUI support tasks and communicates with the ZF8042A by way of a high-speed serial connection.
