Use Frequency Modulation to Send ASCII Data

Several years ago, Tom completed an ultrasonic transmitter project built around a PIC16C84. Now, he returns to this subject to explain the importance of frequency modulation and describe how it's used to send ASCII data. In his latest project, Tom switches to a '16C54.

HTML The PSoC RangeFinder

A Simple Ultrasonic Distance Meter

Some distances are more difficult to measure than others. Therefore, Fabio built his own ultrasonic rangefinder, which won First Prize in the Cypress PSoC design contest. It can be used for measuring liquid levels, generic distances, and even the depth of snow.

ARMs to ARMs

Part 3: Working in the World of ARM

Now that you've been fully assimilated into the world of ARM, it's time to get to work. In this final installment of Robert's series, he demonstrates how to implement the ARM architecture in CPU and system cores, tool chains, and tools. Now, you don't have to rely on the x86 or 68K.

HTML Silicon Update

Going Mobile

After popping the hood on another concept car, Tom started thinking about LIN technology. Clearly, car makers are hyping the value of it, and soon, other industries are likely to hop on the bandwagon.
