A TRULY SOLDERLESS BREADBOARD - PART 2
by Al Williams
Last month, I showed you how easy it is to build logic circuits using a Xilinx CPLD (Complex Programmable Logic Device). This month, we'll dig into a more sophisticated design. In particular, I'll show you how to build a useful piece of test equipment — a "logic scope." This is a poor man's logic analyzer. The logic scope reads four bits of digital data, records them, and then displays the waveforms on a normal oscilloscope.
PICK THE NETWORK PROTOCOL THAT’S RIGHT FOR YOUR DEVICE
by Jan Axelson
If you have a device that you want to use in a local network or on the Internet, one of the decisions you’ll need to make is how the device will exchange information with other computers in the network. Many devices host web pages that display information and enable users to send input, but web pages aren’t the only option.
UNIVERSAL SERIAL BUS
by Hamid Namdar
USB is the answer to the development of all the new external peripherals for the PC platform. USB is low cost, fast, easy to use, bi-directional, and capable of real time data transfer of voice, audio, and video. Currently, USB 2.0 has a bandwidth of 480 Mbps, which is 40 times greater than the previous version — USB 1.1 — with a fully compatible bandwidth of 12 Mbps.
