Hardware and firmware design, development, and testing of an automotive ECU for interior lighting application

A vehicle is made of many different components, each of them serves different functions may be critical or non-critical. Ferrari, like many other car manufacturer, relies on tier 1s to develop components of each vehicle. Sourcing from a Tier 1, increases the cost of production with respect to an in-house solution, as a matter of fact the goal of this work is to produce an in-house component that might be used in future vehicles; a dome light is used as a test subject, a non critical component that is used to light up rear seats. Development is done according to the waterfall model, that offers a simple way to iterate through different designs. Hardware design went through two iterations, that were helpful to address errors and missing functional requirements. At last this "exercise" proved that designing a component internally can be very valuable.
