Security Goes Beyond Cryptography
March 20, 2008 9:45 am | by Jon Titus, Senior Technical Editor | Articles | Comments“When engineers start to network devices, security becomes a top design requirement,” said Tim Stapko, lead software engineer at Digi International. “But many designers of embedded systems just don’t think about security. When they do, they might consider security as an add-in option or think of security as simply encrypting communications.”
GPS Modules put Products on the Map
March 20, 2008 9:42 am | by Jon Titus, Senior Technical Editor | Articles | CommentsWhen a product such as a child locator, surveying instrument, or autonomous vehicle requires position information, a GPS module can provide it. Prices for devices that provide this information range from less than a dollar for chips used in cell phones to hundreds of dollars for modules and boards that offer high accuracy. Cell-phone GPS receivers might get you “close enough,” but higher-end modules can offer centimeter accuracy. “At its simplest, a GPS receiver acquires satellite signals, decodes their information, and calculates a position, time, and velocity,” explained Joel Avey, director of marketing at Trimble for the company’s advanced devices.
Physical Layer Package Expands FlexRay Testing Capability
March 20, 2008 8:00 am | Product Releases | CommentsProviding eye diagram mask test and physical layer measurement parameters to LeCroy’s WaveRunner Xi oscilloscope for FlexRay testing, a physical layer test package combines with existing protocol triggers and decode tools to create a single instrument that can conduct advanced FlexRay triggering, protocol decoding and physical layer test. Allowing automotive engineers to effectively debug the FlexRay protocol and efficiently verify signal integrity, the solution includes tools such as trigger and decode for CAN, LIN, I2C, SPI UART with mixed-signal oscilloscope options make the package well suited for embedded controller design and debug with support for 10 Mb/s, 5 Mb/s and 2.5 Mb/s standard data rates.
