Fax Technology for Embedded Systems

Fri, 06/29/2012 - 05:55
Data communication options for embedded system designers are expanding at exponential rates. One low cost option for transferring information is the use of off-the-shelf fax modem technology. Small, reliable, and economical (less than $100.00) single part faxmodem/DAA packages are available from several sources and can be called upon to send text and graphics to the most ubiquitous printing device in the world - the Group 3 fax. With some accommodation, the same technology can be used to send half-duplex data at 9.6 and 14.4 kbps from embedded systems.

Students need to learn multiple programming languages

Thu, 06/21/2012 - 08:01
Adacore’s Greg Gicca thinks computer science and engineering students need to be taught programming languages are tools, just like hammer and screwdrivers, and that just as when you a building a house you use the tool appropriate to the task, it is necessary in any software engineering application to use the programming language appropriate to the task.

Optimal digital power control using LLC resonant converters

Sat, 06/02/2012 - 00:55
The authors describe a digital power control implementation using line level control (LLC) resonant converters based on a flexible, 32-bit, low-cost, high-performance microcontroller. Key elements of digital power control are explored; including duty cycle control, dead-band adjustment in real time, frequency control, and adaptive thresholds for maintaining different safe operation regions.
