Microchip says that the development kit enables designers to leverage the capabilities of its dsPIC33 GS series of digital signal controllers. Together, the controller and reference design reportedly enable designers “to create a 100% digitally-controlled ballast function, while including advanced features, such as dimming and color hue control.”
Applications include dimmable LCD backlighting, signage, LED replacement bulbs, architectural lighting, and automotive lighting, such as daytime running lamps and signal lights, as well as the automakers’ Holy Grail – headlights.
The question of whether engineers could have foreseen the shortcut maintenance procedures that led to the crash of American Airlines Flight 191 in 1979 will probably linger for as long as there is an engineering profession.
More than 35 years later, the post-mortem on one of the country’s worst engineering disasters appears to be simple. A contractor asked for a change in an original design. The change was approved by engineers, later resulting in a mammoth structural collapse that killed 114 people and injured 216 more.
If you’re an embedded systems engineer whose analog capabilities are getting a little bit rusty, then you’ll want to take note of an upcoming Design News Continuing Education Center class, “Analog Design for the Digital World,” running Monday, Nov. 17 through Friday, Nov. 21.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
