Practical Application for TDD
Part 1: Write Software in a Test-Driven Development EnvironmentTest-driven development (TDD) in the embedded environment is an important concept to learn. In this series of articles, a group of imaginative designers puts the idea to the test. The end result is an interesting temperature calculation project.
HTML Zeroing in on ZigBee
Part 2: Chipsets and Source CodeLast month Pete introduced the ZigBee low-power radio standard and underlying IEEE 802.15.4 layers. In this article, he describes the development resources you'll need to create your own ZigBee projects. He covers both the chipsets and the source code.
Stealth Keyless Entry System
AVR 2004 Design Contest WinnerThat 10-button keyless entry pad might be more hazardous than helpful. An intruder can discover your code by studying the wear on the buttons. David tells us how he built a better system.
Control an FPGA with I2CIs the I2C bus a good candidate to control an FPGA? Roberto thinks so. In this article, he makes a case for I2C based on a careful study of its capabilities. He also shows us how to drop an I2C module into an FPGA.
Single-IC 10/100 Ethernet SolutionThinking about implementing embedded Ethernet hardware? Try Freescale's MC9S12NE64. With this powerful tool, single-IC Ethernet is a no-brainer.
From the Bench
Joystick TechnologyAn analog joystick would be a great addition to some designs, but space limitations could present a problem. Fortunately, new devices like the JS1100AQ five-position joystick navigation switch can help you solve the space problem.
'51 FavoritesThe '51 has been around for more than two decades, but today's '51s are vastly superior to their ancestors. This month, Tom looks at where '51 technology has been and where it's going.
