Automotive steering-wheel angle sensor provides data over the CAN-Bus

Orchid Technologies combines cost sensitive engineering with precision analog electronics to craft high-performing, stable, sensing electronics. Ease of calibration together with reduced cost electronics
requires skill and ingenuity. Orchid provided a number of electronic hardware assembly options, allowing our client the opportunity to tune sensor performance for reduced-cost applications or high- precision
applications.

Orchid selected a Freescale HC08 class microcontroller as the brain of
this steering angle sensor. The Freescale HC08's feature-rich complement
of flash program store, static RAM, Eeprom, CAN-Bus controller, timers,
analog-to-digital conversion circuitry, and robust processor reliability
controls make the HC08 a perfect fit in the automotive electronics
marketplace. Codewarrior software development adds a world class
programming environment to the development process. Well- tuned software
libraries provide advanced features such as 64-bit floating point
functions and trigonometric functions. Real-time calculation of double
precision floating point trigonometric functions was rapidly
accomplished by the Freescale HC08 microcontroller.
